[Elecraft] Breakers for KPA1500?

[N2TK, Tony]

I do not understand the need for three wires plus ground. For a clothes dryer outlet a neutral is required to get 110VAC from one of the phases to the neutral. But for amps you only need both phases and a ground. The plugs are three wire, not four.

Not only a suggestion -- it's the law! Electrical Codes carry the force of law, and they require that the equipment ground must 1) run with the current carrying conductors and 2) must be no smaller than the largest conductor.
