Swimming pool feeder

[sparkync]

Can someone tell me where it says you can run 4 wire SER cable for a pump pool as long as it stays inside the house, but once it comes out of the house it has to be in another approved method, such as "PVC" etc., I know this use to be in the code but I can't find it now. Maybe they've taken it out?
thanks

Might depend on the Code cycle. In 2017, 680.25 Where installed in noncorrosive environments, feeders shall
comply with the general requirements in Chapter 3.

680.21 & 680.25
This changed in the 2017 code. If the wiring is run in a non-corrosive area, then any chapter 3 wiring method can be used.

Looks like me and the "youth challenged" guy posted at the same time!

Isn't the issue that the EGC must be insulated outdoors?

Yes, but that changed when they added the "corrosive area/environment" part. Now, if you're aren't running conductors in those areas, any chapter 3 method is allowed.

So, according to what I read, a #6/4 SER cable can be run from an inside panel to a pump disconnect on a wall on the exterior of the house? Is this allowable in the 2017 Code? That is what NC is going by for "residential" at the time. Thanks

Yes, as long as the area doesn't have anything that would cause it to be classified as corrosive.
So if you're not running it through a chemical room you should be good to go.

If the disconnect is in the area of the pump it would be considered a Corrosive Environment.

680.14 Corrosive Environment.
(A) General. Areas where pool sanitation chemicals are
stored, as well as areas with circulation pumps, automatic chlorinators,
filters, open areas under decks adjacent to or abutting
the pool structure, and similar locations shall be considered to
be a corrosive environment. The air in such areas shall be
considered to be laden with acid, chlorine, and bromine
vapors, or any combination of acid, chlorine, or bromine
vapors, and any liquids or condensation in those areas shall be
considered to be laden with acids, chlorine, and bromine
vapors, or any combination of acid, chlorine, or bromine
vapors.

Ok, I can see maybe where the conduit or flex feeding the pump will have to have an insulated ground, but the feeder to the disconnect will be coming in the back of the disconnect, or through pvc feeding the disconnect, and will not be exposed to fumes or vapors. The disconnect will have a "dead front" on it, and if it is brought out of the wall to the disconnect. it will be protected by pvc. I guess the vapors will still "seep" through the openings around the edges of the dead front. Seems the "terminology" of corrosive environment is sort of confusing. If I could not run SER cable without an insulated ground, I would have to run PVC through the attic from an inside panel and run thhn all the way. I know this is the normal way of doing it when coming from an outside panel, but poses a problem when coming from an inside panel as described

I don't think 680.14 is talking about in open air outside. They specifically mention areas under a deck where the air is less likely to move about. Just My Opinion
