Re: changing 3wire 240v to 4wire 240v
I'll have to plead ignorance, I have never heard of using a quick disconnect on a house. Normal house wiring from a power company to a house is 3 wire, 2 hot and one common. The common is reference to ground. The wiring goes from a transformer to a Meter base and then to the main breaker box. A ground rod is installed near the house and the ground wire is run from it to the breaker box and is connected to a bus that is used to connect all grounds and the common wires for 120 volt circuits. At least thats the case in the U.S..
