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.

What are you installing this breaker for?

A true 240 volt load has no neutral and needs no neutral. Connected to a GFCI breaker, there will be no problem.

I am installing this is my main breaker panel for my hot tub. The previous breaker wasn't a GFCI.

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?

I'm sorry, I had a brain fart...it IS this:

Neutral from GFCI breaker to neutral bar, nothing on the neutral terminal.
One hot on each of the other terminals.
Ground from hot tub to grounding bar (left this where it was).

You are fine now.

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