For example, to connect 4 modules in one cabinet to a single phase input requires two
#8AWG main inputs or one #4AWG main input.
* N/R — Not recommended. Connecting 4 equivalent loads to a three phase source in
delta configuration will create an unbalanced load. It’s usually more feasible to run a sepa-
rate #10 AWG line directly to the 4th module.
