If a 50a 240v outdoor spa has the GFI on the plug, can I run the circuit not using a GFI breaker?

I believe if you feed a gfci device with another gfci device it will nuisance trip.
The gfci plug or disconnect should suffice which will be fed by a 50 amp dp breaker.

Edward,

If the Tub has a Cord and Plug the receptacle itself must be GFCI protected. It makes no difference if there is a GFI on the plug or not.

See:

680.42(A)(2) for outdoor locations.
680.43(A)(3) for indoor locations.

I am not aware of a 50 Amp, 240 volt GFCI Plug - The spa should be protected by a circuit breaker - also, having a GFCI breaker feed a GFCI receptacle will not cause tripping of either device. Only ground currents will trip them.

I perfer the spa disco. 50 or 60 amp models mostly. 240 volt. self contained 3R enclosure. comes with a dead front GFI which is attached to the coil of a contactor. Feed it from a regular circuit breaker.

This spa does have a built in GFI in the control box. I suppose I wouldn't need a GFI breaker then? And since the panel is within sight, I wouldn't need a disconnect at the spa either.

Al,

You said it has a plug. If there is an outlet for this Tub the outlet itself has to be GFCI protected, it doesn't matter what is in the Tub or on the plug.

See:

680.42(A)(2) for outdoor locations.
680.43(A)(3) for indoor locations.

Bill, no it doesn't have the plug, I wired it direct, but there is a GFI built into the spa control panel. Think I will put a GFI breaker in too. That will protect the line going out to it.
