Good point about using the same AC supply, my system has a ganged 30A at the main breaker box. that supplies pump and lights and SWG (seperate CBs in the control box though).

I'm not sure whether having the SWG already powered up when the pump turns on would be better or worse under these conditions.

I still think it is bad to have SWG and pump on same AC line, but running an extra AC line would be expensive - running it in same conduit as the pump would mean derating the wires for both, i.e., using larger than normal wire sizes
