220 wire to 110 wiring. The red and black wires in 220v circuits carry 220 volts across each other but 110v in relation to the neutral which is the white wire in a four wire cable leaving the green or bare copper. It doesnt matter to which cord the plugs are attached as long as they match up to their mating socket as explained in the following steps. Hot neutral and ground. To convert a 220 volt circuit to 110 volts first the circuit must be positively identified back at the source panel.
Get yourself a certified electrician. Attach a male 110 volt plug to one cord and a male 220 volt plug to the other. When you convert 220 to 100 volt wiring you have to cap off one of the hot wires and install a new single pole breaker to replace the double pole breaker used for the 220 volt circuit. It would be best to place a one pole circuit breaker in place of the two pole breaker.
If you need to use a 220v receptacle for a 110v appliance an easier solution is to use a 220 to 110 adapter. Adjoining wire paths might be revealed roughly where certain receptacles or fixtures have to be on an usual circuit. A typical 110v wiring schematic requires three different wires. Electric motor wiring diagram 220 to 110 building wiring representations reveal the approximate areas and also interconnections of receptacles illumination and also irreversible electrical solutions in a structure.
