I had an instructor in tech school that said he liked working with 480. Generally there were enough black marks to find the problem. My help installed a new pump panel yesterday and when he turned it to Hand operation the contacts on that block went into self destruct Mode. Came wired from factory with L1 and L2 wired to that contact. Due to supply shortages it was not are normal PP supplier, so no control fusing on this brand. He said it was quick and noisy.
