This is an FP Panel I looked at Saturday. Aside from the FP panel and aluminum wiring advisory, I think the Perf board surrounding the panel is a problem. I also didn’t see neutral and ground busses bonded. There is a main cutoff on the outside of the house with a 150 Amp breaker but no bond apparent there. There were no fault indications for polarity on any of the wiring in the house. could the bus bars be mounted directly to the panel and be bonded by the metal panel?
Thanks in advance
