Service upgrade

[Trovmar]

Hi guys, quick question i was told today that you can only use schedule 80 pvc conduit for a service to a one family dwelling. He proceeded to tell me that if i use schedule 40 pvc i will fail inspection. Is this true?:-?

If he is the AHJ.
You may be in an area that requires it.
Generally it is used when coming out of the ground.

I have seen guys spin the writing around when they bought the wrong pipe to make it not as obvious.

See 300.5(D)(4).

This is an age-old trick around here, and often times, it's just plain difficult to tell whether it's 40 or 80. :smile:

Tell him to prove it.

In general, the answer is not the one that he gave you.

80 vs 40

80 vs 40

I usually require SCH 80 where the conductors are unfused and SCH 40 when it is fused. However check with local AHJ for specifics.

It is true here for the pipe below the meter base.

This is always a call by the inspector. Schedule 40 cannot be used where subject to physical damage. That is a very subjective rule. 352.10(F)

Here it is required by the POCO

This is based on........:-?

That is ok as long at the conduit is on the line side of the service point. The utility has no right to make rules for anything, other than their meter, that is on the load side of the service point.

No Sch40 here

Were aren't allowed to use Sch40 here at all for service risers.

One POCO will allow Sch80 risers, the other requires Steel Risers only.

Probably because the intense sun breaks down the sch 40 easier than 80.

I did a service at the beach in SC and they required galvanized risers there for that same reason.

Same in Colorado Springs... from meter to panel: Sch 80 PVC.
From transformer to Meter: GRC (with tape when in contact to the earth + 18" above grade)

Something about being subject to damage. I will agree that Sch 80 is a fair bit tougher than Sch 40. And well, nothing comes close to GRC...

For unprotected lines, it is always GRC... (here anyway)

I can say that I have seen people wipe the markings off of Sch 40 (PVC glue works great... or so I've heard... :wink: ) or flip the pipe too...
