I have an existing 480/277 panel sch.load calc.Need to add 390 VA into existing circuit (on A phase) which is 2567W (based on existing load calc) at 277V.
The new load is continuous so 390 X 1.25+2567=3054/277=11.02~12amp?
The phase B and C will stay unchanged.
Neutral load will be increased by the same amount as phase A?
Thank you
