Does a UF feeder for a well pump in a commercial building have to be sleeved in conduit the entire way under the pad. I say it does, but the well contractor says they have never been called on this before. What do you guys think?
 
Direct burial cables are not permitted to be installed under a slab within a building unless installed within a raceway, take a look at Table 300.5 row 3 coulmn 1.

Raider, thanks for the response. I already quoted chapter & verse to the well contractor but he claims since they are running the UF wire along with the water line that "other" inspectors never make them sleeve the UF wire, so I was wondering if their were any others out there who have heard of this "exemption" for well contractors.

It dosn't sound like the "Other" inspectors know the code. I hear all kinds of excuses and "exemptions" from contractors. I have learned to take these "exemptions" with a grain of salt. I can't tell you how many times I hear "The inspectors in ______ don't make me do that".

Thanks Chris, I talked to a state electrical board representative here, and he agrees it has to be in conduit under a building. If the well contractor complains I guess I'll just ask to see his Electrical License, then ask why he's running electrical wire without one.

Your welcome,

Sounds like you got a good plan.;)

When I first moved to NC in the late 70's the well pump contractors would run a twisted TW 3 wires down the well to the pump and then would also use the same wire underground to the house. They would lay the wire on the water line and run it across the crawl space to the holding tank as well. Those were the days.....;)

Why, have those days ended? ;) They still use well pipe for the well conductors around here, I generally just stuff some carflex into the end of it and terminate it into the control box.

Sticky, they were running the TW underground-- no conduit--- to the house and laying it on the ground in the crawl.

I know i've seen it done... but do you think well pipe is a legal conduit?

Nope-- but it's better than no protection at all. You know what happens when you're not protected. :grin:

Not a problem if they use UF as some guys do, but not for the pump cable.

I actually had to rewire the pump at my parent's house because they ran ungrounded!! pump cable to the pump, and since the pump had been replaced a few times it was butt spliced, and the butt splices were in bad shape (not sealed correctly. I pulled the old pump cable out of the well pipe they ran into the house and replaced it with UF, and used those Ideal wirenuts that come filled with gel to splice it at the well head. So far so good. :cool:
