i replaced several 3 way switches in my living area with 2 pole switches....because I'm not an electrician and didn't know there was a difference. After learning of my mistake, I replaced the 2 pole switches with new 3 way switches, however, now the wires to two pair of the switches aren't receiving power. On wall A is a 3 switch panel, with switches that control the hall light, ceiling fan, and fan light. The hall switch functions properly, but there is no power to the other two switches. On wall B is a 3 switch panel, with switches that control the fan, fan light, and kitchen light. None of these switches have power. On wall C is a 4 switch panel, with switches that control the garage light, one that controls unknown/nothing, the kitchen light, and the dining room light. The garage is 2 pole and works properly. The dining room works properly. The kitchen switch has no power. So, the ceiling fan and light, and the kitchen light switches aren't receiving power, and the breaker is on. I need help please.

I have just acquired a new (to me - actually very old) power saw with a 3-phase motor. I will be running it from a VFD fed by a 240V dedicated line. I want to have a small worklight over it, and want to know if there's any safety / code reason I can't tap 120V off the 220V line to run it. The saw should draw about 12A max, the worklight will be an LED fixture of maybe 10W. This is the planned wiring diagram.... [ATTACH]49747[/ATTACH] Any advise or comments, please? EDIT - Please disregard the 'attachment' diagram. I can't see how to remove it. The Neutral line does not go into the VFD. Richard
