Yes, it has a test button. Perfect for our installation.
You can just replace the breaker. Buying just the breaker alone is sometimes more expensive than buying the whole spa panel and discarding the enclosure. Just check current pricing. You can buy these spa panels in 50 or 60 amp.
Any GE THQL 2 pole GFCI breaker will fit. It may be cheaper to just buy the whole spa panel. Check current pricing.
There are 3 concentric knock outs on the bottom of the enclosure as well as a possible hub location on the top. the largest KO is a 1" I believe with the other 2 going up to 3/4
You may be able to fit a seimens breaker in this panel but it is a code violation because it is not listed for a seimens breaker.
This panel can be fed from the top. Whenever feeding from the top in a NEMA 3 enclosure it is important to use a hub. Purchased separately. This will insure a water tight fit and maintain the UL listing.
There are 3 -1/2”, 2 - 3/4 “, 3-1”, 1-1-1/4”, 1-1/2” and 2” . This is all available knockouts however 3 of the 4 knock outs are concentric meaning they are combination. 2 go from 1/2” through 1”. 1 goes from 1” through 2”. The 4th is only 1/2”. Hope this helps.
On the load side wiring the red and black wire go to the right and left breaker screws. The load neutral, (white) goes to the center breaker screw. The most common mistake is terminating the load neutral to the neutral bar vs the breaker. This will cause it to trip.
The included breaker will only protect the circuit that is connected to it. It WILL NOT protect any other circuits installed in the panel. You will need a separate GFCI breaker or feed into a GFCI receptacle and use the feed through wiring of the receptacle to protect that circuit.
Jared.....in view of the latest information you posted, the kiln still should not need GFCI protection, but the receptacles might since the floor doesn't seem to me to be finished. It's really a judgement call on the part of the inspector. I think I would go ahead and GFCI protect the receptacles using a GFCI receptacle. Even if the inspector requires you to GFCI protect the kiln circuit, you do not need this separate panel, just install the GFCI breaker in the GE main service panel. That being said, the least expensive way to buy a GE 60A GFCI breaker is to buy either a GE or Midwest spa panel w/GFCI breaker, remove the breaker and throw the enclosure away. A breaker alone will cost more than either of the spa panels that come with the GFCI breaker. This all depends on the version of the NEC your town has adopted and the inspector makes the final call.
