So I have installed electric to at least 50 indoor "Jacuzzi" tubs in my years, (do mostly commercial) but i didn't realize until today they were all wired with Romex. Now I just ran into an issue in a multi story condo using MC cable to wire a Jacuzzi the same way I have for years. The inspector here in Pompano Beach FL is telling me to bond to article 680.62B. I assume he is referencing sub paragraph (3) "Metal sheathed cables and raceways and metal pipes that are with in 1.5 meters (5') of the inside walls of the tub and not separated from the tub by permanent barrier" Yes, I bonded the copper pipesHow do I bond the MC cable? A pipe ground clamp? I assume with that logic I will also have to mount a lug on the outside of the 1900 box housing the GFI?
Lesson learned either car-flex or smurf for this type of application in the future.
 
Single set screw clamp type MC connectors with lock nut, approved for the use. The MC is connected to two 1900 boxes, one for the GFI and the other to what was the original GFI location but is now a junction box, because they turned the spa around,due to drain pitch. (there is access for both sides of tub). From the junction box it goes home in MC.
 
I wonder if he was referencing art. 680.26(B)(2) --perimeter bonding. If so there may be an exception to that in 680.42(B)
 
Reading 680.42 (b) , if items 1-4 are met it would seem no further bonding is required , the only '17 change might be on 1, The spa or hot tub shall be listed, labeled, and identified as a self-contained spa.

I suppose i'd be looking for the label.....

Some kind hearted poster sent me this last time i asked....

I bonded the motor and the copper water lines, I believe the rest is (usually) plastic. I didn't notice anything abnormal with tub install. Going today, I will see if there is something unique about this tub and there is something else metal I have to worry about.

But at the end of the day 680.62B.3 states that I have to bond the MC. I guess i will use a ground clamp and see what happens???

I am talking about the perimeter bond that may be required, around the outside of the tub

I don't see how the MC sheathe is not bonded since it is in a listed connector.

Perimeter items that are required to be bonded must be bonded via no smaller then 8AWG bonding jumper. Not real clear on what this equipment mentioned is. If not connected to the spa at all I think no question he needs to run an 8AWG out to it somehow. If this MC cable terminates in the spa control panel then that panel is already part of what is required to be bonded and I think just connector in metal control panel is probably sufficient.
 
The old if it don't move bond it shtick?

Yeah, methinks we've all gone bond goofy to pass a few jobs Sun dude

When you said Jacuzzi tub I'm not sure whether your talking about a Hydromassage Tub or Hot Tub and Spa. The rules are very different and I can't tell but it looks like you may be dealing with a Hydromassage Tub and would only have to do the following.

680.74 Bonding. Both metal piping systems and grounded metal parts in contact with the circulating water shall be bonded together using a solid copper bonding jumper, insulated, covered, or bare, not smaller than 8 AWG. The bonding jumper shall be connected to the terminal on the circulating pump motor that is intended for this purpose. The bonding jumper shall not be required to be connected to a double insulated circulating pump motor. The 8 AWG or larger solid copper bonding jumper shall be required for equipotential bonding in the area of the hydromassage bathtub and shall not be required to be extended or attached to any remote panelboard, service equipment, or any electrode. The 8 AWG or larger solid copper bonding jumper shall be long enough to terminate on a replacement non-doubleinsulated pump motor and shall be terminated to the equipment grounding conductor of the branch circuit of the motor when a double-insulated circulating pump motor is used.
 
Which is what I did in he first place!!
