I just finished helping a friend energize a second-hand Jacuzzi.
A few issues:
The Jacuzzi came with two hots and a ground, but no neutral. I have a two pole GFI protecting the Jacuzzi, but I only assume that the GFI will function fully without a neutral on the load side.
I should mention that the GFI is in the main panel. There is a disconnect panel by the Jacuzzi but it has a conventional two pole breaker in there.
Apparently the Jacuzzi has an electrical issue of some sort. When I first fired up the GFI breaker it held for about four seconds before it tripped. I tired it three times, and each time it was the same story. When I turned off the breaker in the disconnect panel, the GFI held, so I think I can say that the problem is in the Jacuzzi.
What I wonder is if there is some sort of anomaly due to the lack of a neutral? Is the breaker tripping due to a ground fault, or is there an over current? Possibly I should switch in a conventional breaker to see if it would or would not trip under the same load.
Currently there is no water in the Jacuzzi, so I wonder where a ground fault would be coming from.
But I am also confused as to why the GFI breaker holds for four seconds. I have never seen a dead short hold for even a second. I cannot imagine why the breaker behaves as it does.
Any thoughts?
