We just got a used hot tub. It ran fine where we purchased it but since we got it home, it has not run. We installed a new breaker for the hot tub and an GFCI outlet outside. The hot tub inself has a GFCI installed on it. If we plug it into the GFCI outlet it runs for a few seconds and either trips the circuit inside or the hot tub. Is it necessary to have a GFCI outlet outisde if the hot tub has one? We are thinking that this may be our problem..redundancy. Can we install a regular outlet outside instead of the GFCI outlet? When we plug it into a regular outlet it runs. We want to make sure that this is safe before proceeding.

Did you install the tub yourself? Who did the wiring? Redundant GFCI's should not be an issue. You say the GFCI receptacle trips and the breaker trips at the panel, right. If it is intermittent tripping it could signal non-compliant wiring or a defect in the tub itself. Just because it worked before means nothing.

If this tub was installed correctly, I would suspect the hot tub is the issue. I would call a service tech, preferably one familiar with your particular model tub.

Installing hot tubs and pools are not a DIY project. This is matter of life and death. Tripping GFCI's are doing their job of protecting you and your family. Something is not right with the tub or installation. Get some professional help.

Something is wrong, bypassing it is not the answer. What does the manufacturer call for in terms of electrical power? Is this one of those small tubs designed to plug into any standard 120v, 20A outlet?, if so there maybe some troubleshooting you can do. If this is a larger unit, then there are many more requirements and factors involved in a safe setup.

From whom did you purchase this unit? A dealer or someone else? There is no guarantee that this was installed correctly before, just because it was "working fine".

Is the circuit breaker a standard breaker or a GFCI?

If it is tripping a GFCI, there is a problem, either with the circuit, or the tub itself.

Most hot tubs are not "plug and play". They require higher amperage circuits and special considerations.

You say you plugged the hot tub into a GFCI outlet. This must be something like a portable unit, right? So all you have is one 15 or 20 amp plug to power it up?

I've had problems with plugging in a GFCI protected appliance into a GFCI device. Years ago I bought an electric pressure washer. Every time I plugged it into the exterior GFCI receptacle, the PW tripped it. When I took the GFCI plug and connected that to a receptacle inside (not GFCI protected) no problem. Everyone I talked to at work said you can't connect one GFCI device to another because one will trip the other. Maybe technology has improved since then but I wouldn't automatically rule it out.

If I was troubleshooting this I would first have to eliminate the the redundant GFCI situation as the problem before assuming anything else.

There's a hot tub forum you could go to and ask members there. Google 'what's the best hot tub" and look for the forum. There are hot tub technicians who are members there. Make sure you provide your make, model and year it was made with the other information.

Funny, I've never had problems with redundant GFCI's. As an example, the built in GFCI of my hair dryer works just fine plugged into a GFCI recptacle.

Yeah, that's what I was referring to about technology improving. My electric pressure washer is probably close to 20 years old. The OP never said how old the hot tub is. Gotta cover all the bases when troubleshooting and do the easiest ones first.
