pvc sch 80 used as service lateral riser

[spark1]

Is the use of sch 80 pvc acceptable as service lateral pole risers everywhere, or just in certain locations?What i am trying to say is can i use sch 80 pvc on state highways, or do i have to use rigid metal conduit?I don't find any referance in the code where it prohibits the use of pvc on state roads.It just says that i can use rigid, intermediate, or pvc sch 80 conduit.

The highway departments all have their own rules, which normally far exceed the NEC. I haven't seen anything but RMC used on state highway work around me. I built some services for the railroad (Conrail) and they all had to be RMC.

The answer to this question is found in your poco's "Guidelines for installations" or their "Green [or whatever color it happens to be] Book." They will specify when you can use PVC and when you can't. It's a mixed bag in my area...some require RMC all the way up, some require it for the first 10' coming out of the ground, and some don't use RMC at all for pole risers, even for HV lines.

Yep, just about every state and municipality have their own rules just like most electric utility. :smile:

One of the serving utilities I work with requires RMC within 25 feet of the highway where subject to vehicular traffic, i.e., where mounted on a quadrant facing the street. If the conduit is placed on the back side quadrants away from traffic, schedule 80 is permitted within this 25 feet.

And I note that the utility around here uses PVC for risers on poles right next to the street. Primary or secondary, pole top to underground.

I see many of these broken from time to time.

Schedule 40 by my eyes. :-?

I've never really understood the logic of requiring RMC on pole risers. It seems to me that if a vehicle is going to hit a pole, it's going to damage the riser whether it's in PVC or RMC.
