What is the purpose of not bonding the neutral bus bar to the panel housing on a sub panel? And does the same apply for a ground? I intended to run another ground bar in the same proximity as the sub panel and ground the panel through the wire feed and the local ground bar. Thanks Leslie

I recently managed to reverse over my power washer! the main problem I caused was wrecking the on/off switch. I have just disassembled it but the bits are all loose and I don't know how they were meant to sit. It seems to be a basic on/off switch with 2 metal bits that I assume sit on the middle bit to act as a rocker - but there are also 2 ball bearings running loose - haven't got a single idea where these belong!! Can anybody possibly explain to me how to re-build this switch (so I can find out if this was the only damage I caused!) preferably with a diagram!!?? Alternatively if there is a web site I could look at for help??
