My friend at work just put a hot tub in and the tub has no neutral lead to connect to. It just has two hots and an EGC. (It does have a little transformer inside the motor housing for a small 120v load. )

If you dont pull a neutral to the hot tub then how does the GFCI breaker work? (with the curly white pigtail.)

He just hooked up the two hots to the breaker and the test button worked fine. Is the breaker testing for leakage between leg a and leg b on the single phase system. and do you only hook up the white curly cue off the breaker when you have 120 v loads?

He said that the instructions to the GFCI breaker said to hook up the white curly cue if necessary. Does this mean to use it only if you have 120 v load coming from this source ( the panel with the gfci breaker)as opposed to the little transformer (sds) inside the motor housing.

According to the C/H catalog the DP GFI senses both voltage leads and the neutral lead for the ground fault. The white lead (neutral) is used if there are 120V loads.

The typical way to connect the neutral on 2 pole GFCI breaker is (the line side neutral is usually required for the test function):

Connect line side white wire (the curly one on the breaker) to the panel neutral

If available;
Connect neutral from the load to the neutral lug on the breaker.

Often the breaker does not require all of the load lugs to be used. You can skip the neutral and even either one or more of the hot legs.

A lot of the newer tubs do not require 120 volts. They work strictly off 240 volts. In which case you do not need a neutral. However the 2 pole GFI still has the neutral wire on it. That should be hooked up as normal ( Also as the manufacture requires) and everything should work out just fine.
