Does the pool filter motor have to be on a dedicated feed?
Can you install the convience receptacle on the same feed as the pool motor?
Any thoughts?

I don't find any requirement for the pool pump to be on a dedicated circuit without other outlets.

If the pool pump is hardwired, then this rule applies:

210.23(A)(2) Utilization Equipment Fastened in Place. The total rating of utilization equipment fastened in place, other than luminaires (lighting fixtures), shall not exceed 50 percent of the branch-circuit ampere rating where lighting units, cord-and-plug-connected utilization equipment not fastened in place, or both, are also supplied.

So if you want receptacles on a hard wired motor circuit, then it can only draw half of the circuit's rating (which isn't likely with most 120V pool pumps).

The light circuit would be a better candidate for the receptacle but be aware of the "unspliced EGC" rule when you lay it out.
I pulled 2 EGCs when I did mine. The unspliced one went to the J box and another was used for the receptacle, switch etc.
My pump is 240v. I figure the I2R savings will pay for the extra few bucks I paid for the breaker ... eventually.

680.22 (A) (3) "Dwelling unit(s). Where a permanently installed pool is installed at a dwelling unit(s), no fewer than one 125 volt 15 or 20 ampere receptacle on a general purpose branch circuit shall be located not less than 3.0m (10ft) from, and not more than 6.0 m (20ft) from, the inside wall of the pool."

I would say a circuit for the pool motor is not a general purpose branch circuit, thus the convienience receptacle can not be fed from that circuit.

Branch Circuit, General-Purpose. A branch circuit that supplies two or more receptacles or outlets for lighting and appliances.

I suppose it all depends on if a pool pump is an "appliance" and if the light is "lighting".
They didn't have any problem with my receptacle on the same circuit as the wet niche light. (Lee Co Fla)

gfretwell, I don't understand the post about 2 equipment grounds and how that plays into line loss. I2R

Can you explain?


Dnk.....

With a 240v motor the loss in the wire will be less (increases with the square of current)
A wet niche light required an unspliced ground to the J box (with a few exceptions).
Since I was also feeding another circuit from this (the receptacles) it was easier to just pull 2 EGCs and avoid any confusion.

Sorry, I didn't notice you switched topics in your post.

Somehow(I dunno),I thought you were suggesting an EGC had something to do with line loss.

I will plead temporary insanity. I was digging in the yard and I was delerious when I came back in to post that. ;-)

Sorry for the confusion.
