What voltage does Tuff Cable operate at?

Tuff Cable is a low-voltage system powered by a step-down transformer that reduces the supply voltage — typically 120V, 208V, 240V, or 277V AC — to 65 volts or less at the cable. This low operating voltage is one of Tuff Cable’s key safety advantages over line-voltage systems, and it also allows the cable to be cut and spliced in the field, and to be installed in surfaces where line-voltage systems are not permitted or practical.
