Romex® NM-B Cable
Romex® from Southwire is a wide-reaching electrical wire used in several types of dry indoor wiring applications, mostly for homes and small businesses. It is available in many different configurations and sizes and offers a special jacket design that makes it easy to pull through conduit. And when you buy from WesBell, you get exceptional customer service and cut-to-order services to make it easy to select and install your Romex® cable.
This cable is specified as non-metallic because it has a PVC jacket and is used indoors only. Metallic Cable, or MC cable, uses an aluminum interlocked armor for a jacket because it also works as a conduit for indoor applications. NM-B cable would need to be installed in duct or conduit if it were being used in the same application as MC cable.
A Romex® NM-B cable uses the following component materials:
- Insulation: PVC
- Jacket: Nylon
- Conductors: Annealed soft copper
- Ground: Bare copper
With the help of these materials, Romex® is rated for:
- Temperatures of up to 90℃ in dry locations.
- Ampacity limited to 60℃.
- 600 volts.
Romex® wires are indeed very useful. However, always bear in mind that they have a very sensitive nature. Harsh, outdoor conditions can quickly cause this cable to deteriorate. Complying with the National Electric Code (NEC) before you set a wiring project in motion can save you lots of trouble.
