Someone told me that a 50 amp. hot tub does not have to be GFI protected. Just bonded with a #6 bond wire to the panel. (Also with a disconnect.) He claims that only 15 and 20 amp. circuits require gfi protection. Being I am not as indebth to the NEC as most of you. Could someone please tell me if the advice I am given is true..

James Article 680.22 A (5) (2002 NEC)
"Receptacles that supply pool pump motors and that are rated 15 or 20 amperes, 120 volt through 240 volts, single phase, shall be provided with GFCI protection." It is section II permenatly installed pools but both section 680.42 and 680.43 reference compliance to section I and II.

I don't think a hot tub is required by the NEC to have GFCI protection if it is hard wired. If it is cord and plug connected, 680.43(A)(4) will require GFCI protection. The listing instructions may also require GFCI protection.

Every Hot-tub and Spa I have seen says in the instructions if hard wired use a 50 GFCI breaker, a lot of the units that can run on 120 volts have a gfci built right into the cord.
I wouldn't want to put one in without it being GFCI protected.

This gets a little clearer (I think) in the 2002 code. 680.4 requires compliance with parts I & IV of the article, part IV is the section that deals with hot tubs & spas.

680.42 has some additional wiring requirements for outdoor installations.

680.44 requires GFCI protection. Of course, theres the usual cast of exceptions.

Every hard wired tub I've seen has GFCI protection mandated in the instructions.

Im not sure of the brand but there is a 50 amp disconnect with built in gfi protection made for hot tubs. I see it at my supply house every day, let me know if you want more info.

In the code Handbook under 680.44, It says, "The requirements of 680.44 specify that field-assembled Spas and Hot tubs with heater loads of 50 amps or less are to be GFCI protected"
I cannot imagine putting one of these units in without GFCI protection, Lloyds of London wouldnt have that kind of money for the insurances and the lawsuits.

motor,
You are correct, 680.44 does require GFCI protection for the hot tub outlet. I missed that.

That is what I thought.. Just have to becareful who you take advice from.. I mean to say many of the older homes here on long island are run on a 60 amp service. So lets take that service and feed a hot tub! It would be stupid not to GFI protect it..
