Dirt supports PVC?

[George Stolz]

Do you need a strap within 3' of a CT can if the bottom of the can is 24" above grade?

ETA: What if the pipe extends from concrete?

IMO definitely not required for concrete, dirt maybe maybe not.

 

[Cow]

No, but I'm guessing this is a trick question somehow?

 

[George Stolz]

I'm looking at 352.30(A).

 

[Ponchik]

So another words can the dirt or concrete be used to support the conduit, if it is within 36" of the enclosure?

IMO, will work just fine especially with larger conduit and with concrete, but only the AHJ will decide.

I never have in either case.

Nothing will support the conduit better than encasement in poured concrete.

If dirt is not a support, will the post I use to mount the panel on be considered a support for the strap I use for the conduit, because it is in the dirt? Now to go look up your code reference

If encasement in the dirt is not support, then your underground runs better have some straps on them, I don't know what you will secure them to though.

If there is some inspector questioning this make him this proposal: Lets bury you in the dirt and see just how securely it keeps you from moving and/or getting yourself out.

Trick questions no....

When I saw who posted this question, I had the same reaction. Then George posted the code section, I wonder if he is looking for confirmation. My opinion is absolutely not. If 1 foot of dirt properly compacted isn't "securely fastened" then we are in trouble.

George, how are you accounting for 300.5(J)?

If this is the same job I've been doing electrical inspections on for George. POCO cuts the trench & installs the lateral. No, I don't make George install a strap that close to the ground!

 

[Dennis Alwon]

Power company never installs straps even when the lateral is 4' above the ground. It is never plumb either.

 

[George Stolz]

Actually, a student in my class was asking, and I didn't feel 100% confident that dirt/concrete qualified as a strap. I also wanted to show the class how to post on the forum, so here we are.

Many thanks for the replies.

If it is 4' above ground it is a service drop and not a lateral:lol:
