3 Things to Know When Buying Electrical Wire

There are several different aspects to consider when faced with an electrical project. However, most people tend to overlook one of the main concerns while shopping for their equipment; namely, the wires.


Know Your Ampacity

Ampacity is the word used by the National Electric Safety Code to describe the maximum electrical current that a conductor will allow. When an electrical wire goes over its ampacity, it causes either progressive or immediate damage and can cause serious problems like a fire. Generally, ampacity ranges from 10 amps, as with a low-voltage light, to 200 amps, which powers service doors at stores, and every variation between.


Get the Right Size

Electrical wires do a variety of things and it’s important to know which size is needed to handle the project. Size is generally determined by the wire gauge system, which correlates oppositely with ampacity. This is because the amount of ampacity that a wire will carry will grow but the size of the wire will shrink. For example, a service panel that has an ampacity of 100 amps will use a 2 gauge wire while an extension cord that uses 13 amps will have a 16 gauge wire.


Keep Wires Protected

In order to keep wires safe from damage and corrosion, it’s best to have them sheathed in some form of plastic. Non-Metallic Sheathed Cable, or NMS, are often considered ideal for indoor wiring because of their sturdy casing, and some outside wires are available as well. There are three different types of NMS wires available and each one has their own individual strengths. These types are known as NM, NMC, and UF.

  • NM- NM wire is commonly used indoors and is perfect for lighting and receptacle circuits.
  • NMC- NMC cables are ideal for damp areas inside of the home. This is because of the extra insulation that these wires are coated in.
  • UF- UF wire is meant to be used outside and underground. Although these wires are fairly hefty and insulated, it’s important not to use them above ground because the sunlight can destroy the strength of the sheathing.


DLO 4 AWG Electrical Cable

You might need DLO cable if your application has to do with diesel locomotives, oil and gas drilling rigs or telecom power supply. DLO stands for Diesel Locomotive which is the main application for it but it has very good approvals and ratings for industrial power equipment that gets inspected on a regular basis.

DLO 4 AWG electrical cable is rated for 2000 volts due to its dual insulation. It’s manufactured with tinned copper strands which makes it more flexible than other types of electrical cables such as THHN THWN wire. The insulation also makes it more flexible because rubber will help it bend easier than typical PVC insulation with a nylon coating.

One thing to remember when deciding which cable is best for your application is to realize that a 4 AWG wire is a 4 AWG wire. No matter what stranding option it has to make it more or less flexible it will still have the same diameter and transmit the same amount of electricity. The stranding options are geared towards flexibility because as copper AWG sizes get larger the copper becomes harder to handle.

Applications that require electrical wire to be sent through conduit or snaked through a home or building will be manufactured in a less flexible way. A stiff THHN THWN wire being pushed through conduit will glide right through with less of a struggle compared to a flexible welding cable that will get bunched up as it’s being pushed.

 There are a few cables very similar to DLO cable such as welding cable, Type W and stage lighting cable because they all have rubber insulation. They are considered portable cord because of the rubber and they each vary slightly with temperature, voltage and approval differences. DLO 4 AWG cable stands out with a 2000 volt rating and all approvals needed to pass inspection such as UL, CSA, RHH, RHW, MSHA and RoHS. These approvals are stamped onto the jacket to prove that UL, and the rest, have tested and approved it as compliant to the temperature and voltage ratings.

Engineers are continuously improving their cables and creating new ones to supply any possible application with a specific cable. Once they make a single conductor portable cord rated for 2000 volts, such as DLO cable, someone else will need the same thing rated for 3000 volts. Make sure you speak to your wire and cable suppler about your application so that you’re positive you’re using the correct wire with the approvals needed to meet the NEC code.

THHN Electrical Wire 12 AWG Solid Bare Copper

THHN 12 AWG solid wire is engineered and manufactured to be a less flexible type of electrical wire. All applications call for different types of wire based on the environment they are placed in and they also have preferences that the user can choose from that may differ from contractor to contractor. The insulation isn’t the only thing to consider as an installer or electrician using electrical wire on a day to day basis.

THHN 12 AWG electrical wire is manufactured in a solid and stranded format based mostly on preference. The solid version is one 12 AWG solid strand of copper which needs to meet a certain outer diameter. This is used in homes and buildings to connect the electrical box to outlets, lights and appliances. The user of solid THHN wire would rather have a stiff wire that holds its form in order to install it in conduit or snake it through a wall of a home or building.

THHN 12 AWG stranded wire is manufactured with 19 strands of copper instead on one solid strand as mentioned above. The strands are not 12 AWG each or the wire would be considered a much bigger gauge size. Instead, the copper strands are much smaller and wound together to equal the same outer diameter of a solid strand of 12 AWG. Copper transmits a certain amount of current based on its size so the 19 strands need to meet the same exact size or it will not be considered a 12 AWG electrical wire.

Again, it’s completely a preference of the user. Some contractors, installers and electricians like flexible wires and some like inflexible wires based on how they complete their installations. Suppliers constantly answer the question, “Can I get 12 AWG THHN wire in a more flexible version”? The answer is yes. There are many types of electrical wire and building wire that suit the preferences of each user.

Speak to your supplier about getting something more or less flexible because they, or their manufacturer, will most likely have something to fit your needs. It might mean getting a different type of insulation as well but they will make sure the new type of electrical wire is still approved for the job in which you’re using it. Even stranded THHN wire isn’t very flexible compared to single conductor portable cord wires with rubber insulation. The strands are incredibly small and the rubber insulation also adds to the flexibility.

Copper Strands in Electrical Wire

Copper is the best conductor of electricity and the most widely used commodity in electrical wire and cable. Different sizes of copper are twisted together to create varying flexibility in gauge sizes used across the industry.

Bare copper ground wire doesn’t have any insulation covering the copper and it’s normally one solid strand. A 30 awg copper strand is more flexible than a 2 awg copper strand because of the size. The bigger it is the less flexible it can be, similar to thin a metal rod being easier to bend than a think rod. Therefore, when discussing the flexibility of a wire or cable the size of the copper strands play a big part.

THHN electrical wire comes in the option of solid or stranded copper depending on the amount of flexibility you need for your application. One might need it to be flexible so that it can bend around corners while another might need it less flexible to push it through conduit easier. The PVC insulation and nylon coating also limit the amount of flexibilty of THHN building wire.

Welding cable is known to be much more flexible in the industry for two reasons. The first is the 30 awg copper strands compared to THHN’s 19 strands that get larger as the wire gets larger. The next is the rubber insulation which is much more flexible, and expensive, than PVC. With a rubber jacket there will be almost zero chances of it cracking or splitting during installation unlike THHN wire.

Talk to us about your needs so that we can help you find the correct product at the right price for you. You may think you need welding cable but after discussing your situation with us we might find that you can use something less expensive without compromising the application.

Information About Foil Tape And Tinned Copper Shielding

Copper is commonly used for shielding purposes, usually as a foil tape or tinned copper shielding. Information about foil tape and tinned copper shielding is readily available online. Both foil tape and tinned copper shielding are used to shield cables, eliminate EMI/RFI interference, thermal and electrical purposes and others.

Foil tapes are available in two kinds: aluminum and copper. Both are conductive acrylic adhesive. Foil tapes are used for purposes that require reliable point-to-point contact like EMI/RFI shielding, static charge draining and grounding. These foil tapes have many uses in electronic design, prototyping for test laboratories and for design and troubleshooting purposes. Copper foil tapes in particular is a cost effective to shield against EMI/RFI interferences. It is very easy to apply and therefore, time saving. Copper foil tapes are conductive all throughout including the adhesive which makes it ideal for cable shielding, shielding electrical connections between surfaces of sheets and foils, die-cuts, temporary shielding during tests and as an antistatic.

Tinned copper shield is available in mesh and flat braid. Tinned copper shielding (flat braid) is rolled flat and braid at the time of manufacture. It is very flexible which makes it a great protective braid over hoses and tubings. It is also useful for shielding around cables, ground straps, battery grounding, and as bonding strap for vehicles, aircraft and marine equipment. It also eliminates ignition interference and can be used for any application that needs woven, tinned copper braid. Tinned copper shield has minimum shield coverage of 95%. Specifications QQ-W-343 type S and ASTM B-33 are met for woven tinned copper shields.

More information about foil tape and tinned copper shielding including the thickness, approximate awg, ampacity and others differ depending on the type of tinned copper shielding to be used as well as the shielding capacity of foil tapes which also differ with its size. Copper Foil tapes are available in typical industry standard metric cut sizes, example, 24mm for every 1 inch of nominal tape width ordered. Note that rolls are 5% narrower than the nominal size. In this case, the product’s actual size is 25.4mm wide.

The conductive adhesive of copper foil tapes is ideal for modifications of printed circuit boards, repairs of security alarm circuits and for layout and design of wiring board prototypes. It is very ideal for wrapping cables to shield EMI/RFI and to provide electrical continuity by seaming of EMI/RFI shielded rooms. It is also used for draining of static charge and surface contact to materials such as plastic or aluminum which is non-solderable. Its copper-bright color is non-tarnishing and annealed making it also great for arts and decorative projects.

For better shield coverage, tinned copper shield is recommended. Its woven, tinned copper construction provides a minimum coverage of 95%. It has a nominal thickness of .020” making it very flexible and ideal for use as bonding strap for marine equipment, aircraft and vehicles.

You can find other specific information about foil tape and tinned copper shielding at the manufacturer’s website or you may give them a call for more assistance needed.

Speaker and Audio Wiring: Some Tips You Need to Consider

It must always be a boost to have a very beautiful acoustic sound emanating from your audio system. Whether it’s in your home or in your office or business area, it always feels good to hear quality sound. So, look for the best speaker and audio wiring and try not to go with a very cheap product.

This guide will help you familiarize yourself more about the exact length, proper gauge and correct speaker wire for your sound system. The gauge that you need for your speaker wire is based on the approved thickness range from 12-gauge to 16-gauge. If the gauge is low, it means that the wire is thick and has better capability to amplify sounds.

The audio components and speakers also help determine the best electrical wire gauge. Of course, you should also consider your budget for this. Another factor, too, is the distance of the amp and the speakers. This means that the longer a wire is, the poorer its reception and transmission capacity of the sound and its quality. Thus, if the wire needed must be long, it has to be thicker or at a lower gauge.

However, the need for a thicker speaker and audio wiring is also based on certain circumstances. If you want full sound quality from a music system, home theater, and the like, then the need for a thicker wire is really acceptable. You will be able to enjoy every minute detail of the music or every sound effect of the film or audiovisual media.

The standard 16 awg wire is acceptable and very satisfying for speakers that are close to the receiver. It is also the most recommended type of gauge wire when you are strictly on a budget. It can be used when routing or running it through some wall holes, door frames, or base boards of the room.

Another factor that helps determine the quality of the speaker wire is the materials used for its making. If it is made of metals, it is expected to have better conductivity. Other high quality speaker wires are designed to have more special construction and video shielding to keep the sound system and the same components from any interference.

The wire you need is also dependent on the measurement. Try to be slack in measuring the distance between the receiver and the speaker including the possible obstructions, loops and turns of the wire. Add some extra length to the final measurement. You must also check that the wire running through all the speakers have the same exact measurement. They must be quite long, too, to ensure resistance. The similarity in measurement for the wires of the speakers is checked so that all speakers will receive the same amount of volume and power.

Further, you may use a standard speaker and audio wiring if you want a simple but equally effective sound quality. Look for wires that you can repaint, allowing it to complement with the color of the room. Make sure that you observe electrical safety measures for your speaker wire and other electronic components.

3 to 1 Adhesive Heat Shrink Tubing Protection

Man is able to come up with innovative ways to protect electrical wire and cables through the years. Aside from the usual plastic coating or flexible sheaths, technology has provided for the development of tubing that is not only reliable and durable, but waterproof as well. It is a well known fact that moisture (or in general, water) has adverse effects on wires and electronic cables. Water can bring about corrosion and unnecessary disintegration of the conductor which may lead to greater losses, be it in residential, commercial, or industrial applications. Hence, the need for a reliable protector created a demanded for more creativity and innovation on the part of developers of wire and cable.  

Take 3 to 1 Adhesive Shrinkable Tubing as an example. It is developed around the idea of having two distinct parts, namely: the inner wall and the outer wall. It is important to note that the materials of construction used for each wall are two different components or materials. This is due to the fact that they are bound to play different roles in the shrinkable tubing. The outer wall is made of Polyolefin and is referred to as the heat shrink. On the other hand, the inner wall is commonly made of adhesive that melts down when subjected to heat. Since the tubing is made of two walls, it is usually referred to as dual wall tubing.

What happens to the 3 to 1 Adhesive Shrinkable Tubing when it is subjected to heat? Something good is bound to occur once the shrinkable tubing is subjected to temperature slightly lower than the known temperature of activation of the heat shrink. Once the optimal temperature is achieved, inner layer begins to take the gel form in such a way that it is like a stream of glue. After undergoing the process of heating and after everything cools down to the normal temperature, there exists a layer of adhesion between the shrinkable tubing and the wire. Not only that the resulting system is water proof, it is also assured that the wire or the component inside the shrinkable tubing will not experience any unnecessary movement that may be detrimental to the entire purpose of the electrical wiring.

The “3 to 1” in the nomenclature of the shrinkable tubing is rooted from the fact that it shrinks to 1/3 of the original diameter after subjecting it to the process of heating and cooling down. In addition, there is an estimated 15 percent average shrinkage rate if we look into the wire’s longitudinal aspect. In terms of standards, 3 to 1 Adhesive Shrinkable Tubing complies to the benchmark set by AMS-DTL-23053/4. The tubing can operate at temperatures between -55 degrees Celsius and 110 degrees Celsius. The shrink temperature is estimated to be at 90 degrees Celsius. The upper bound temperature, beyond which the tubing is expected to disintegrate is around 135 degrees Celsius.

Aside from insulation, this tubing can be used in wire identification, bundling of connectors, wire strain and stress relief, and insulation of solders.

Voice Communications Wire: Coming Up with the Best Base Material

From the time Alexander Graham Bell made use of a wire to transmit a human voice to the present time when contemporary voice communications wire technology dominate the communication industry, there can be no doubt about the claim that much more improvements in voice communication are in the offing.  For this reason, you would expect stiffer competitions in the electronics industry because the public clamors for better quality of communication.

The advent of the cellular phones as the primary tool of communication had made the exchange of ideas and information more efficient and faster but complaints about communication glitches with the most modern of communication technology still prevail.  Some of these complaints are traceable to the quality of wires that are used to absorb and transmit sound waves.

In the present time, when economic slump is likely to remain for a longer time, business remains to be robust because consumer demand continues to rise.  One area that needs to upgrade in technology is communication.  People need effective and efficient communication to perform their businesses to be able to produce enough money to support their family or finance their business.  This calls for electrical wire and cable companies to come up with advanced research which are designed to look for ways to improve the quality of voice communications wire.

With easier access to communication (especially through the internet), consumers are increasingly being exposed to information on technology.  They do not just buy gadgets at a whim; they also ask what kind of materials is used to make these gadgets.  They do not just buy cell phones; they ask which telephone companies are producing these cell phones.  Other customers would even ask which company suppliers (or countries) supply the specs of these cell phones.  That also occurs when they buy iPods, computers, sound system and the gadgets that they use when engage in some business or academic presentations.

As already said, communication to people is very important.  Everyone knows that and they need the kind of communication system that produces unhampered, clear and fast delivery of sound units.  People want a system that they can rely on especially during the time when the so-called communication traffic occurs.  Unfortunately, communication failures abound and that is really irritating to communication technology users.  It is the responsibility of those who are engaged in the exchange of communication goods to come up with the best materials in the communication technology.

The exchange of ideas among people (and peoples) is more likely to magnify in the coming days – that is very much inevitable.  It would be dangerous to think that people will just settle for what kind of system that they have now.  If they will, they would better not trust in the present system and do away with technology once and for all.  Consumer confidence is a necessary factor in the life of the business world.   The lack of it can suck the life out of businesses from which people acquire their means of living.  Everyone must focus on producing the best materials for communication technology and it must be now.

The world needs to come up with the best voice communications wire.

Toughest Multiconductor Instrumentation Cables in the Market

Selecting the best type of multiconductor instrumentation cables is not an easy task. There are various criteria that you have to consider like voltage, flame resistance and the presence of moist or any other chemical resistance that could occur in the process. In addition to this, if you are planning to mix different brands of instrumentation cables, you should have the right technical skills when it comes to this part. Take note that anything can happen if you are not able to correctly construct the wirings.

In these difficult times, each and every homeowner should keep a close watch over the kind of cables or wires that they use in their home. Most accidents are caused by substandard materials and this should not be the case if the owner of the building had been careful enough in scrutinizing the kind of cables that were used. Deciding to let an expert electrician handle the job would also be best but you have to make sure that the person whom you are going to hire is a licensed electrical expert.

A lot of people use multiconductor cables because of the. The stranding of the wire is solid and the purchaser thereof is given the assurance that the bare annealed copper has the robust filler. There is a need to properly scrutinize all your cables and make sure that the commodity is suitable for the type of indoor or outdoor connection that you are currently working on.

You very well know that working on an outdoor instrumentation wiring entails a lot of preparation. No matter what kind of extreme weather condition you have like high temperature or below zero degrees, it is imperative that your outdoor line is still functioning properly. When it comes to your indoor connection, your lines of wirings can handle possible leaks. Most homes or buildings have the same pathway for water lines and electrical wire. If this is what you have in your place, then you have to see to it that the conductors are properly cabled with the use of fillers.

You should also need to construct the round-core just to make sure that the overall effectiveness of the instrumentation cables will be achieved. A greater number of electricians use the over-all aluminum mylar shields as well as the drain wire that is to be utilized to cover the center. The best thing about using instrumentation wires is that you can easily install these items in free air, in race ways or even below the ground. The so called “direct burial cable” procedure is very common and you do not even have to worry about the wetness or dryness of the ground when dealing with the ground works.

Just remember that you have to select the most flexible instrumentation cable for the connection that you make more so if the location is an industrial area where there are various hazards. The insulation capability of the multiconductor instrumentation cables is considered superior.
