Pvc

[ultramegabob]

here is a couple pics I took today of some pvc pipe ran above a suspended ceiling in an office tenant space being renivated, it is cutting diagnally across a tenant space that is doesnt serve to feed a panel in the tenant space next door, whoever installed it pulled 4/0 urd quad to feed a 200 amp 3phase panel and must have realizied that they forgot that they needed a ground wire, so they black taped and zip tied some #4 bare copper to the outside of it....

It is good to see so many starting to post pictures.

It is not good to see the EGC on the outside of the PVC.

its not good to see power from a differnt meter chasing through the inside of a tenant space either

Not the first time I've seen an install like that. EGC can be outside of pipe.. 300.3 (B) This install just shows off this installers PPP. Ugly Install

In small retail spaces, we see this all the time. Even in attached condo projects we see this. I would not be too concerned, as they are feeder type conductors.

I hate seeing pipe ran diagonally across buildings

which portion of 300.3 B do you feel that this complies with ? ( I read through all the listed sections and exceptions and I can't seem to find one which allows this installation).

Thats not what 300.3(B) allows. The exception in 250.102(E) only allows this for 6 ft and less. With the EGC on the outside the circuit impedance is much higher on a ground fault.

300.3(B)(3)....?

...sheath...nevermind.

I like the grey #10 thhn hanger in the last picture or is that a piece of ceiling wire?

 

[ultramegabob]

I think its probably a piece of solid stripped out of m.c. cable, the same guy that installed this is the one who had the j-box in this service risor, its the same building differnt tenant space.

Even in a non-metallic conduit? :-?

Depends if you're the one with 'free' electricity
