I recently had an inspection fail because I had installed schedule 40 PVC RNC for the line side of the meter can and as a nipple between the meter can (600a( and the main disconnect ( 600a 2p CB). The conduit come underground and turn up along the wall where the meter can and disconnect are mounted.The area in front of this equipment will be a concrete sidewalk.

The inspector wants me to replace the sch 40 with sch 80 PVC for the conduits entering the meter can and he wants a ridgid galvanized nipple between the meter can and disconnect(along with grounding bushings).

Other than a concern for physical damage, which I do not believe is the case since there is a concrete sidewalk, is there some other code section that prohibits my instaslltion as stated above?
 
Re: Ridgid Nonmetallic Conduit

I don't have my codebook in front of me right now, but I'm pretty sure I once saw something about how cable emerging from underground has to be protected with RMC, IMC, or Sch.80 RNC. That might explain why the inspector wants the Sch.40 changed for Sch.80.
 
Re: Ridgid Nonmetallic Conduit

I don't know of one other than subject to physical damage 352.12c which is the judgement call of the inspector. as for the pvc nipple between the meter and the disconnect,,,,,,,here we go again.Everyone is saying do not pull a ground wire between the meter and the main disconnect,use the neutral for the sole source of bonding and grounding on line side of service disconnect,prevent parallel ground paths,my response to that is ,the only way to eliminate parallel ground paths from the main disconnect to the meter is to install an insulated nipple between them which is exactly what you did and you got tagged for it.
 
Re: Ridgid Nonmetallic Conduit

we got taged for the 6 inches of shed 40 just under the CT can yet the poco used 40 going up the pole.I know poco does not need to comply with nec but why not ? this was flat out stupid, no way could our 6 inches get hurt but a car could easily hit the line going up the pole :roll:
 
Re: Ridgid Nonmetallic Conduit

Around here it is standard practice to use PVC between meter can and disconnect. Who wants to install all those bond bushings. :( POCO generally installs everything on the line side of meter. As Jim says, they dont have a problem with Sch. 40.
 
Re: Ridgid Nonmetallic Conduit

We went to PVC nipples in the 96 code change and yes sch 80 is required for NEC inspected services to tired to take the code book out or open the CD ROM but its there.What I have a problem with is as JIM said the pocos can use sch 40,but we had to change all our T poles to sch 80 or RMC,BTW we just did a count there are 1,500 T poles out there $$$$$$$$$$$$ :eek:
 
Re: Ridgid Nonmetallic Conduit

Just where do we stand on a T POLE if it meets code when built why would we be forced to upgrade it? are they not grandfathered in ?

No.
If they were, we wouldn't be required to install in-use covers on the receptacles.
