Tray Cable – Underground Multi-Conductor Electrical Wire

Tray cable has become a very big seller over the past year for WesBell Electronics. We started selling all types of electrical wire over 5 years ago to compliment our already booming electronic line. Tray cable has been a very easy sell for many reasons in the electrical industry.

Our type TC-ER tray cable is manufactured with THHN wire conductors and a PVC water tight jacket which makes it available for direct burial in the ground. It’s round with a black jacket and all black conductors that are numbered for easy installation. It ranges in awg sizes from 18 to 750 mcm with up to 4 conductors and a ground wire.

The reason it’s such an easy sell is that it has all the bells and whistles with out the outragous pricing. Copper still weighs heavily on the price because it’s so high right now but other cables manufctured for the same undergound use have a higher expense.

Type MC cable is slightly cheaper because it can only be used in conduit. If you want an MC cable that can be direct buried you’ll need the additional PVC jacket over the metal clad armour. That makes for a very expensive cable but it can also be used in concrete which tray cable cannot.

Many of our customers call and want to use Romex® for their application. Then they say it’s only going outside for a few feet so it should be fine for this situation. Well that’s not true. Romex® doesn’t have the protection that UFB cable and tray cable have because it’s only made to be used for indoor applications. That’s why it’s cheaper and that’s probably why they want to is it over the more expensive cable, but getting tray cable first is better than replacing the Romex® later.

Tray Cable is the Newest Electrical Wire Addition

The newest product addition to WesBell has been tray cable because of the amount of uses this type of electrical wire has. It’s universal in a sense because it can be used just about anywhere without an oversized jacket.

THHN / PVC Tray Cable is the standard type with THHN wires and a bare copper ground wire. Each wire is black with a number code of 1 through 4. The tough outer PVC jacket has the approvals for direct burial in the earth.

Another type of underground cable available in this field is UFB Cable. The difference with UFB wire is that it’s color coded and flat rather than round. It’s the common step up in smaller applications up to 6 awg from Romex and MC cable. Romex can be used indoors and MC cable can be used outdoors but not directly underground.

However, if you need a bigger gauge underground cable then tray cable sounds like a good fit for your application. It’s 600 volts type TC-ER tray cable and comes in copper conductors only.

There are many types of electrical wire types even though most of them come with copper conductors. Each insulation type is a step up from the next to offer a variety of pricing. Obviously and indoor only cable will be cheaper than one that can be buried directly in the ground because of the approvals and tests it needs to go through. So be sure to tell your sales person exactly what you’re using your electrical cable for in order to pay the lowest price possible.
