I bought a hot tub off a little old lady who had been having a lot of trouble and gave up frustrated. Her son told me that the installer ran it on a 220 volt system. I ran 6 ga wire to a 50 amp GCFI disconnect box. When I got the hot tub, I noticed a normal 3 prong outlet plug sticking out of the side of the hot tub wall. Upon further inspection, there was about 12' of 12 ga. wire coiled up inside the hot tub housing.

Inside the AP1400 controller I saw:
L1 had black in and black out
L2 had nothing coming in and red going out with two little white wires connecting to the neutral
Neutral had white coming in and white going out
Bare copper attached to proper location.

I am an amateur electrician. I have wired whole houses in the past and I did all of the preliminary wiring before the Hot tub arrived, but I do not know what to do inside of the AP1400 beyond running black to L1, red to L2, white to neutral, and bare copper to its appropriate place. I assume that those two little white wires connecting L2 and Neutral need to go. My thoughts are that the guy who istalled it for this little old lady was an idiot, but what I don't know is, what did he change inside the AP1400 to make it function or am I all wrong and it is supposed to be on a 110? What are the things that I need to look for? I will try to send a picture that has my new 220 wires coming in to the AP1400 and the rest of the wiring was how it looked when I received it.

I appreciate any help that you can offer.

Defiantly remove the 2 white wires and you should be good to go.

It kicks on. Runs for 10 seconds and then snaps the breaker. If I disconnect the blower, it will not trip the breaker. I took the blower out and connected to a 15 amp outlet and it ran fine. Could it be that additional electrical modifications may have been done to run this system on 110? Could it be that this system was designed to run on 110? (My hunch is no.) I wish I had a manual, a wiring diagram, a picture of a proper installation, or some help. I am never available to call tech support during the day. Anyway, help would be so appreciated.

Thanks

was the 15A circuit you tested the blower on a GFI protected circuit? You can have a ground fault in the blower that won't trip an ordinary breaker.

It was not a GFI. I have access to one. What will that tell me?

PS I don't know why my last post posted twice.

I would suspect that if you plug that blower into a GFI protected circuit, it would trip the GFI breaker. With the information at hand, I would say the blower has a ground fault, enough to trip the spa's GFI but not a regular house breaker.
