Whirlpool tub GFCI ?
In the area I live, Horry County S.C., we are allowed to use regular GFI receptacles as a feeder for the tub as long as they are not within reach of the tub. One advantage of this is that the outlet can be installed in an adjoining closet and used there for a convenience outlet for cell phone chargers or similar uses, while still providing accessible GFI protection for the tub. As for installing a GFI receptacle under the tub, this will only protect what is plugged into it, not the wires feeding the box or inside the box. So a tub or pipe leak will still not be protected by the GFI.
I have a question concerning grounding for spa tubs. I have had inspectors require us to ground the plumbing fixtures when the tub has a double-insulated motor with no ground screw. My question about this is, when there is an electrical fault and the GFI has failed to stop the flow of AC, would this not make the faucet grounded, resulting in electrocution?
