Not that I don't trust you, but this is the internet. The four wire plugs separate the ground and neutral. A three wire dryer plug would have the ground and the neutral tied together. No, I don't but a three wire 240 volt plug like the one you pictured uses two hots and a ground.

HOWEVER I am all too familiar with what can happen when I ASSUME something, especially when dealing with 240v at 20A. I suspect/assume you simply tie neutral to ground and leave L1 and L2 separated. I don't understand how to convert 4 wire 240v to 3 wire 240v. Keith, I understand how the 4 wire receptacle and plug are wired. Neutral is 180 degrees opposite, legs have different width for keying.
The 14-20 receptacles and plugs should have such color-coded terminals.įorgot the 14-20 has a neutral which is white.both legs will be black, the ground has the lock tab.
White and black are 120 volt 'legs', when measured to neutral. Originally Posted By KeithJ: Silver is white.
