Am I correct in saying that a panel installed for supplying pool equipment MUST be fed from the main service equipment at the dwelling?

It cannot be fed from a sub panel that is currently fed from the main service.

Just like to confirm this since the existing sub is 50’ from the pool equip panel .As piped,the pool panel would be 170’ ft from the main.

considerable cost difference.
Thanks
 
I would guess equipment location could be a factor on where feeder is sourced from. What makes you assume a remote pool vault has to be fed from a dwelling?
 
As I read it, the feeder would have to come from the service panel unless the subp-panel feeder includes an insulated grounding conductor.
(we have a few members well versed with pool installs .. suggest you wait for their input)
 
Augie. I thought so as well but when I saw the definition of Service Equipment per NEC I interpreted that as the "Main"

Is the "Load side of service equipment" considered a sub panel being fed from the "Main"?

Thank you.

It's a dwelling. Single family residence. Where else might it feed from?

I'm not a pool guy, but isn't there some exception for a bare egc in an overall nonmetallic jacketed cable assembly?
 
There is no requirement that a feeder to a pool panel come from the main. In the 2017, an insulated EGC is required only if the feed runs through a corrosive area, otherwise, it can be a chapter 3 wiring method.
 
Looks like it's going to depend on the Code cycle.
I can't find the exception electrofelon mentions in the '14 but it's in the '17 and Bill says '20 is any Chapter 3 method.

Why can't a service feed the remote pool vault? If the equipment is located in the residence then it would be served by the structure service/feeder
Your question seems vague so my answer was short.

Thank you.

My AHJ is not allowing a sub feed to the pool equip panel located in a pool equipment room( even with an insulated, Cu, properly sized EGC) from a panel that is inside the residence that is fed from the Main service because that EGC that is part of the SER cable is not insulated.

That's where I stand with it at this point.
 
Pool chemicals will be stored in the same room as the equipment.
I told him I understood that and therefore the portion of feeder in that location will be Cu Thhn insulated conductors in PVC sch 40 pipe.

He's adamant on an insulated EGC to the Service equipment which is the Main disconnect at the house meter.
 
I'm all for doing things right but when it comes to a considerable cost increase that I have to absorb I'm not going to just "eat it" just because.

And furthering his knowledge would be something I would think he would want to do for future situations.
 
In '17 it looks like "corrosive atmosphere" is the key:

(A) Feeders. Where feeders are installed in corrosive environments as described in 680.14, the wiring method of that portion of the feeder shall be as required in 680.14(B) or shall be liquidtight flexible nonmetallic conduit. Wiring methods installed in corrosive environments as described in 680.14 shall contain an insulated copper equipment grounding conductor sized in accordance with Table 250.122, but not smaller than 12 AWG.
Where installed in noncorrosive environments, feeders shall comply with the general requirements in Chapter 3.
 
Is the inspector behind a cycle of the code book, or just "experienced" and not up on the latest changes? The 2014 NEC (and many previous versions) section 680.25(B) says:

Grounding. An equipment grounding conductor shall be installed with the feeder conductors between the grounding terminal of the pool equipment panelboard and the grounding terminal of the applicable service equipment or source of a separately derived system. For other than feeders to separate buildings that do not utilize an insulated equipment grounding conductor in accordance with 680.25(B)(2), this equipment grounding conductor shall be insulated.

You could always run a pool feeder from a separate building feeder that didn't have an insulated ground, but it sounds like your subpanel is in the same building as the service which is the issue (under 2014 code). Some places have always allowed covered grounds (e.g. NM cable, SER) for pool feeders while others did not.

But the 2017 and 2020 code have changed this and the insulated feeder ground only applies to corrosive areas, so maybe he just needs to be educated.

So tell me how that SER is in a corrosive environment?
