Ok, any ideas about a dedicated ground on a whirlpool tub? Is there a requirement for a separate, dedicated ground to be run from the motor to a ground in addition to the GFCI?
Any ideas?
Thanks

Michael,
My elctricians run a separate ground from motor to the tubs water line which is almost always the easiest line to get to.It's required around here and I have failed a codes inspection once because this exact thing had been neglected.

You folks are confusing grounding with bonding. The equipment GROUNDING conductor should be running with the power conductors back to the banel. The 8 guage BONDING conductor connects to that lug and bonds all siginificant metal objects within 5’ of the water and all electrical equipment connected to the pool. That bond will also pick up the steel in the deck concrete and in the pool/spa shell. In 2005 that also includes a bonding grid under brick pavers.

The topic was on whirlpools. This would be a different case. As well as many different applications. Grounding lugs on equipment are for grounding, right?

Pools, spas and hydromassage tubs are all covered by the same rules in the NEC. There are some differences but the bonding is the same. The green insulated grounding conductor is connected under the end bell cover in the motor with the power conductors. The bonding conductor goes to the external lug.

Agreed, that the bonding is required. Grounds from equipment shall not be interrupted, manufacturers of some equipment specify that a grounding conductor no smaller than number 8 is required to the panel. If a bond is made to available metallic lines and the line is disconnected for repair the required number 8 ground would be interrupted.

Thanks, I got it now. The bare(or covered) 8awg normally present is a “BONDING” mechanism. I wrote a defeciency on a spa/bath that lacked this and it was repaired by an electrician to my knowledge. As I was unable to talk to the electrician I was wanting to be sure what to call it. As I actually called it a ground (in error but still understood by the electrician) I feel stupid but better next time.
Again Thanks
Michael
And yes Dan Bowers, you taught me that but, in all this mess…I forgot. You da man.
