Bathroom wiring

[donf]

I do not have my code book with me at the moment, but I know that all receptacles within a bathroom must be GFCI protected.

Also, if you place the fan inside the dimensions of the tub or shower and it is subject to water spray, the fixture must be a water-proof fixture.

You did not answer my question. When does an exhaust fan need GFCI protection?

[donf]

You did not read my response.

Receptacles are are required to be on GFCI protection.

Is the fan a receptacle?

[sherash]

Its my understanding that if the fan is inside the deminsions of the tub/shower area that it to must be protected. I never done this before but I've been in Large commercial/Industrial for awhile and I know that these codes change in houses often. When I was in houses we designated one countertop circuit for receptacles then ran lighting/fan separately.

Exhaust fan in a bathroom does not need GFI protection.

If, for some reason, the fan is in the tub/shower space, it will only need GFI protection if required by the manufactuer of the fan.

Minimum code does not require GFI protection, however, one can always do better than Code.

Thank-You very much. Do you know anything about Hottub wiring. Outside and Inside 20 thru60 amp models-Grounding and bonding requirements--GFI protection--appropriate means of disconnect--20 amp probably doesn't require disconnect?>? --additional grounding??

[tkrussell]

A 20 amp tub needs a service disconnect, as well as a 50 Amp unit. A 20 amp unit would be or could be a plug in unit, which would serve as the disocnnect.

Grounding is done by the proper size equipment grounding conductor of the branch circuit.

Any tub/pool/spa requires GFI protection.

Inside units can use Romex cable, any outdorr unit would need conduit and an insulated equipment ground.

Your question covers many units and topics, need to zone in on one type of unit to get concise answers.

Someone was telling me about additional grounding requirements for outside tubs--i'd never heard of it. Basically you are saying that I would need a ground from the equipment(tub) back to the last enclosure which would be a non-fusable disconnect located within what 5 ft. of the tub--is this correct?

[sherash]

On a 20 amp outside, could I just snap in a GFCI breaker in the panel. I assume that the 20 amp models are 120 volt. I guess I need 20 amp single pole GFCI breaker plus service disconnect by the hottub or a plug-in.
