Installing a pool and have the feed from power company to my house ran underground. The line has been marked and the question that I have is, how far from the underground power line does the pool wall have to be located. I have heard and read 5 ft. Can someone confirm this? The NEC book that i have has been damaged from water and I am unable to look it up.

THANKS!

680.10 permits wiring to be less than 5 feet from the water IF installed in RMC, IMC or non-metallic. RMC, IMC and NMC to be installed at depths according to Table 680.10.

Don't forget that this is allowable only where space limitations such as property lines prevent wiring from being routed a distance of 5 feet or more from the pool. The way that you posted it beanland, makes it sound like the 5 foot zone doesn't apply if RMC, IMC or nonmetallic raceway are used. :)

Sorry to burst everyone's bubble but the NESC is the proper Code and it permits less than 5 ft with supplementary protection. In other words, I can run a service lateral under a pool in PVC if I wish. For what it is worth, we would not permit that type of installation but that is the call of the serving electric utility. :D

I know you've been busy. But it's always good to hear from you Charlie. :)

Edit: I need a new error number for extra words. :)

Bursting bubbles aside, in my area, the EC is responsible for installing the conduit for the lateral,not the POCO, 3" PVC with 36" cover.By the way, does the POCO in your area have to abide by 680.8 (A)for service drop conductors? :)

Actually, the serving electric utility controls what they install their cables into. The rules are from the NESC or their own standards. We require 4 in. gray PVC, 36 in. deep trench for our cable. We also provide a reducer for installation at grade so the 2? in. conduit will fit into a 200 or 3 in. into a 320 ampere meter fitting.

The NESC requires 24 in. of cover for 600 volts or less the same as the NEC does in 300.5. :D

By the way Redfish, the NESC also covers our service drop conductors, not the NEC. The reason for 230.24 is that is some cases, the customer will install, own, and maintain his service drop. The rules in 680.8 are for those service drops. For what it is worth, the NEC now comes close to matching the NESC. The pool clearances are covered in our overhead standards. :D

It's the same in my area Charlie, sorry I was so vague,the POCO (AEP) requires we install 3" pvc WITH 36" cover.

Re: Allowable Distance from underground feed

Most utilities "layer" their facilities.

Communications - 24 in.
Power - 30 in. (36 in. trench gets you there)
Water - 48 in.
Sewer - over 48 in.

Due to changes in grade, those depths can not be assured. However, this is where most of us start. :D
