No amount of technology found in your home would be useful if you cannot power them up with electricity. And for that to happen, you need electrical wire that will serve as insulated conductors that will breathe life into your home and office equipments.

Electrical wire is made up of very conductive metals like aluminum and copper. They are covered with thermoplastic insulation that will protect them from water, corrosion and other chemicals that may trigger shorts or electrical exposure. The amount of electricity that a wire can conduct entirely depends on its thickness or size. These wire sizes are interpreted in terms of inches or diameter.

For electrical wire to work, you need a specific amount of resistance, circuitry and conductivity. If your wire is narrow, the electricity that will flow through it will face more resistance. The amount of resistance encountered by the electricity decreases the amount of current that will travel the wire. Thicker wires face lesser resistance and therefore contain more amount of current traveling within it.

The National Electrical Code specifies the wiring systems that every household must follow. These codes, which are very strict in nature, protect you and your home by setting standards that will either approve or reject any wiring project that your local enforcement must inspect before being put to action. The wiring system is analyzed based on some factors: your intended use, the amount of power demanded by the wiring system's circuit, and size and type of building where the wiring system will be implemented and the environment where the wiring system will be subjected to.

There are several wiring systems that you can implement in your home. First is the knob and tube system where you can run a single conductor through cavities found between structural members of ceilings or walls. Ceramic tubes that form a protective channel will provide some air between the wire and your walls. This wiring method can protect your home from possible occurence of short circuits.

The use of metal-sheathed wires that will be bonded to the wiring device is what makes this wiring system unique. This concentric wiring system, which encourages the use of metal-sheathed wires will ensure that the system always has earthing continuity.

The use of armoured cables that have two insulated conductors is a better yet more expensive method than the knob and tube wiring system. However, the cables must be handled with care because they will become brittle if exposed to atmospheric oxygen.

Electric wires have two primary types of conductors: copper and aluminum. Copper conductors are usually found in electrical devices because of their very special properties, which make them very practical for use. Copper conductors have high electric conductivity, ductility, tensile strength, thermal conductivity, creep resistance, corrosion resistance and electrical overload resistance. Aluminum conductors on the other hand offer more resistance but weigh less than copper conductors. They are often used when there is a bulk distribution of power and larger feeder circuits.

Electric wires are the only means for people to bring life to their devices. However, this doesn't mean that you must take your wiring system lightly. If a wiring system is not handled with care and expertise, it could bring you more harm than good.

Electrical wire and cable is a high volume item for WesBell Electronics.  This page only has the THHN single conductor wire, so you should see our Romex® or UFB Cable (underground cable) if you're looking for the multiconductor cables. Our electrical wire can be used indoors or outdoors, but if you need direct burial speak to someone on our sales team about fitting you with the correct wire or cable. Our copper THHN THWN wires are used for electrical wiring applications and resist water, gas and solvents. We offer all different wire awg sizes listed below including #4, #1, #8, #2, #6, #12, #14 etc. We can supply you with the MCM sizes as well including 250, 350, 500 and 600. If you're looking for something more flexible try our indoor PVC insulated Hook up Wire on the smaller awg sizes. Try our Welding Cable on the larger awg sizes for something more flexible. WesBell also offers FREE SHIPPING over $250.00. Call now (800) 334-8400 or buy online through our shopping cart!

Our online electrical wire pricing is updated daily to be sure it's up to date for our customers.
