Hello and welcome to Just Answer… My name is ***** ***** allow me a few moments while I do some research, my recommendation will appear shortly.

Ask Your Own Electrical Question

Basically the setup is as follows;

2 pole GFCI breaker has two 120v legs going to the 6-50 receptacle. The white wire on the GFCI attaches to the neutral bar in the panel.

The 6-50 being 240v requires no neutral, instead you need a ground wire from the panel and installed on the ground/neutral bar of the panel. Most residential panels only have 1 ground/neutral bar to share since the ground and neutral basically do the same thing.

Ask Your Own Electrical Question

As an added safety feature, it you are installing a metal box for the 6-50 receptacle, you should ground the box 1st, then the receptacle, using the same wire. This is keep the system bonded as well as grounded.

On diagrams iv'e seen the breaker has one white going to the neutral bar and another going out to the receptacle with the two hot wire. Do I leave the White neutral off and replace it with a ground?

Yes... 220v doesn't require a neutral wire, instead it uses a ground wire.

Thank you

You are most welcome... Another way to think of this is that the wire does the same job (a ground) however the color of the wire identifies what it is exactly. White identifies a neutral which implies that the circuit may not be 220v, but rather 2 120v circuits. The ground wire confirms the circuit is 220v.
