Q: What is the difference between 50 amp 125 volt and 50 amp 125/250 volt?
A: The blade configurations are different. In other words, one system may not be used with the other.
50 amp 125 volt is a 3 wire system (1 hot wire, 1 neutral, 1 ground).
50 amp 125/250 volt is a 4 wire system (2 hot wires, 1 neutral, 1 ground).
Note: Each device has 3 blades. The 4 wire devices are grounded on the side.
