My friend had his basement finished with a bedroom, living room, and bathroom. He asked me to come over today to fix a few things in the basement. I went to change over a bad breaker in the sub panel and noticed that they didnt run a ground to the panel. Also the sub panel was right up against a water pipe. Now the panel is connected to the main panel through a 1 1/4" Riged metal pipe. So my question is could they get away with not adding a ground since it is connected to to the main panel through a pipe? I really doubt it and the funny thing is that this panel was inspected and passed inspection?!?!?

The NEC allows the conduit to be used as the EGC. Its possible your area may have an amendment requring a wire be run.

The water pipe could be adjacent to the PB and still meet NEC requirements. I don't think it can be above or below it, but adjacent to it is ok. I think.

Absolutely, but you still need to make sure the neutrals and neutral bus are isolated from the enclosure, and that the EGC's are bonded to the enclosure.

We use metallic conduits for EGC's containing feeders to panels everyday. This is a common installation practice and when installed correctly it should never be a problem.

Nice photo, but shoddy work is shoddy work. There is no guarantee that this hack would correctly install the EGC either. Much of the reliability of electrical work revolves around the quality of the installation.

Why does the electrician in the original post have to be a Hack? Just asking.


Who said he was a hack? Not installing an EGC in metallic conduit is not hack work if the conduit is installed correctly.

are you serious. i could see if there was a gc installed and the locknuts
were loose but to punch out the side of a can and leave it that way.....well
the shoe fits. all that was needed was a few taps with the linesmens and
all would have been ok as long as bonding bushings were used..

I was thinking the same thing. Not exactly a great deal of work to flatten out that KO.
