FAQ
What is the difference between a 12 2 and 12 3 wiring diagram?
The main difference between a 12 2 and 12 3 wiring diagram is the number of wires. A 12 3 wiring diagram consists of three 12-gauge wires and one ground wire, while a 12 2 wiring diagram consists of two 12-gauge wires and one ground wire.
Can a 12 2 wire be used for a 220 volt circuit?
No, a 12 2 wire cannot be used for a 220 volt circuit. A 220 volt circuit requires a 10-gauge wire or larger to handle the increased electrical load.
Can a 12 2 wire be used for a dryer?
No, a 12 2 wire cannot be used for a dryer. A dryer requires a 10-gauge wire or larger to handle the increased electrical load.
