Tri-Rated Wires and Cables

The name Tri-Rated comes from the fact that this wire and cable meets the specification of three separate standards. These being the British Standards Institute (BSi), the Underwriters Laboratories (UL) Appliance Wiring Materials (AWM), and the Canadian Standards Association (CSA).

This tri-rated wire and cable is a heavier duty wire compared to our other layout wires. This heavy wire is suitable for larger layout DCC power bus wiring. The outer diameter of this wire is larger than the standard wires we sell so has a larger current carrying capacity.
