Romex® NMB Wire Information

Romex® is manufactured with a PVC jacket for indoor use only to cut costs for electrical contractors. I do not recommend even trying to use Romex® in conduit because there is moisture and the jacket cannot withstand it.

If you need a cable to go in conduit I recommend UFB cable which even stands for Underground feeder. Our underground cable can be used in conduit or for direct burial in the earth. UFB is a very popular type of electrical cable because it isn't that much more expensive than Romex and it can be used or stored anywhere.

Romex® wire comes in 250' coils or 1000' spools from the manufacturer but we can cut the cable to length for you as a value added service. We cut all of our electrical wire to length for our customers because it cuts costs for each job by eliminating waste. We sell the Romex® cables in as small as 50' lengths and offer free shipping on orders over $250.00!

Take a look at the Romex® NMB color code by awg size so the electrical contractors can easily identify the size of the cable. Romex 14/2 and 14/3 are both white, Romex 12/2 and 12/3 are both yellow, the Romex 10/2 and 10/3 are both orange and the Romex 6/3 and 6/2 have the black jacket.

All of the UFB underground cables have a gray jacket because it's harder to make the tough rubber jacket in colors. UFB needs the though jacket to protect itself against the outdoor weather.

If you're looking for a different type of electrical wire just email us or give us a call so one of our sales people can find the correct cable for your application.
