About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Machine Tool Wire

More flexible than standard wire, this wire is often used for internal appliance wiring. The strand count is the number of strands followed by the size of the individual strand. The higher the number of strands, the more flexible the wire. Also known as MTW wire, it’s rated UL 1063 for machine tool wiring.

600V AC

UL 2556 VW-1—Flame rated VW-1 wire meets requirements for preventing the spread of flames based on a timed test with vertically suspended material.
