breaker.jpgI installed Square d GFCi breaker for hot tube (Square D QO250GFI 2 Pole Circuit Breaker)
I did have a hot tube installer who told me that this breaker can't be used for hot tube.
Did anybody else have that issue .
If yes can someone explain me why?
Thank you
 
Man, you had me going for a minute there, wondering what the heck a hot "tube" is. But then I realized it was a hot TUB!

There is no reason it should not work, I have that exact breaker on my "hot tube" (OK, OK, I'll stop...).

The thing is, SOME newer equipment that uses Variable Frequency Drives inside can be problematic for some GFCI breakers, and Sq. D is one of those that sometimes have issues. So without knowing any more than what you told us, and ASSuming the installer is familiar with that SPECIFIC hot tub, he may know something about it from experience.
 
sorry for mistakes but this is because of quick typing and English is not my first language .
This is what he told me : because breaker doesn't have a "spot" for load neutral, hot "tube" ;-) will not have line to neutral protection.
Is this sound right?

50 amp QO GFCI breakers have a neutral.

60 amp QO GFCI breakers do not have a neutral and will not work with loads that utilize a neutral.

Make sure which one you do have/need.
 
If your tub requires a neutral then the breaker must have a neutral terminal. Some tubs don't need a neutral so it depends on what you have
 
I used the breaker as on the picture.
We are using square d panel. Only this breaker fit there, and this breaker doesn't have load neutral termination.
Why i can't have both neutral connected to a neutral bus bar?

If your breaker doesn't have a neutral connection, and the tub requires a neutral, you can't run the tub's neutral directly to the neutral bar. This will cause an imbalance that will be sensed by the breaker and it will open.

According to the catalog only the 60 amp version is missing the load neutral termination. If you do have what appears to be a 50 it may be an assembly error at the factory.

As mentioned if there is neutral load the neutral must pass through the current monitor within the GFCI device or else it will be unbalanced and trip whenever there is neutral load.
 
I agree with the others. The breaker you posted is a 60 amp and does not have a load neutral connection. You stated you used a 50 amp and they do have neutral connections.
 
Picture in OP is from wrong angle to determine if there is a load neutral terminal, but does appear to have 60 on the handle.

Because it wont work. The spa neutral, if present, MUST be connected to the breaker. Also note that if you use a GFCI disco you need a 4 wire feed even if the spa doesnt need the neutral; the GFCI breaker needs it.
