Re: california 3-way
The last California 3-way I ran across was between a house and a barn. After the homeowner tried to replace the 3-ways himself, he called me. Three single wires ran through the air between the house and barn. After 3 hours of scratching my head I got it back to the way it was originally wired. The receptacle in the barn stayed hot all the time. Two 3-way switches, one in the house and one in the barn. The polarity through the lamp socket would reverse every time you flipped a switch.
