GFCI Install
I want to make sure I do this right.
I just got a Cutler-Hammer type BR breaker, 50A, 2 pole, 240v.
I went to install this but saw that I have two hot wires and a ground wire, no neutral. Will I be able to use this breaker with no neutral?
Thanks.

Since I have only two hots and a ground, how should I wire in the breaker? On the back I have one terminal marked with a white dot and a white wire coming out. The other terminals have no markings or colors.

You don't need to connect any outgoing neutral, however the pigtail needs connected to neutral.

OK, I hooked it up like this:
Neutral from GFCI breaker to neutral bar, nothing on the neutral terminal.
One hot on each of the other terminals.
Neutral from hot tub to neutral bar (left this where it was).
Thanks people.

The white wire from the tub should be connected to the neutral terminal on the GFI breaker.
Is this wire hooked up at the tub end? Do you have a wiring diagram for the tub?

You are fine now.
You have a 240v tub, NOT a 120/240v. You have no neutral at the tub.
