Wiring method for pool motor question:

[jjhoward]

Does 12/2 or 12/3 UF in conduit meet the requirements for wiring methods per 680.21 (A)(1)?

Or must there be a seperate THHW 12 awg grnd conductor?

Thank you.

IMO, the UF would not normally meet the requirements of (1), but if you meet those of (4), the EGC in the UF should be ok.

Why do say the UF would not meet the requirements of 680.21(A)(1)?

(4) does not apply here, I am running the motor line from a detached garage to an above the ground pool 25' from the garage.

The last sentance of (1) requires "an insulated copper" EGC. The sheath of UF isn't insulation, but UF is allowed to be made with an insulated EGC: 340.108. You just have to find that type.

Thank you volta.
I was not sure about the ground in the UF being insulated.

Oh well, looks like we will be "re-doing" a little work tomorrow.

I had run 12/3 to box on a post for the general use recept at a pool.
Then came out of that box with a 12/2 line for the pool filter feed.

Pool filter needs a 15 amp twist lock recept.

The job was flagged since the pool filter recept was not feed via conduit. I was thinking of simply putting the conduit on the sweep 90s where the UF now lays in the trench from post to post to garage. But I will need to run a seperate line for the filter recept from the garage to the pump.

I hate it when that happens

Yea bull dog me too.

Not making any money re-doing stuff.

Have to make sure we don't do that again!!!

We have only done 6 pools or so over the years...but I just did not check the code book when we did this one.

Looked good....but it was wrong!

680.21 Motors.
(A) Wiring Methods. The wiring to a pool motor shall
comply with (A)(1) unless modified for specific circumstances
by (A)(2), (A)(3), (A)(4), or (A)(5).
(1) General. The branch circuits for pool-associated motors
shall be installed in rigid metal conduit, intermediate
metal conduit, rigid polyvinyl chloride conduit, reinforced
thermosetting resin conduit, or Type MC cable listed for the
location. Other wiring methods and materials shall be permitted
in specific locations or applications as covered in
this section. Any wiring method employed shall contain an
insulated copper equipment grounding conductor sized in
accordance with 250.122 but not smaller than 12 AWG.

I agree...doing work over stinks. But the sense of accomplishment TWICE is good for ya...lol
