You think you've found all the nails-through-wires, but there's one more. I once had a friend who's garage light switches suddenly started operating different lights, and I traced it to a 16p nail that a roofer had put through two separate runs of wire, one of which was a three-way switch send, and the other a regular single send. The nail shorted one leg ...

Now with the problem breaker/breakers off, go through the devices and check if any have a bad wire. I would start with ...

Replace the 20A breaker and goofy three way switch wiring in the house with a 40 or 60A double pole breaker. Continue to use the 100A three conductor (SEC cable). Install a ...

Follow the manufacturer's instructions for wiring the device. If the instructions say make a ground connection, then make it. For argument's sake, that ground could very well be for nothing more than grounding the switch (so it wouldn't necessarily be a pole). However, it is likely that this device is indeed passing some current to ground. Below is a ...
