I am a fan of hand hole's as well, for site lighting they are great! BUT.....make sure you buy a listed/tested/examined (whatever you want to call it) box, once had inspector make a third party test and list all 42 hand holes we used, those were made by Pen-Cell, I believe they have a listing now.
 
110.3 does not require equipment to be listed (see Handbook). It states that if the equipment is listed or labelled, then it must be installed as instructed in the listing. 110.2 states that equipment must be approved (acceptable to the AHJ). 314.30 has the requirements for a handhole.

Also, in a previous post, THHN was mentioned. UG conduit is considered wet location. THHN cannot be used.

I only know of 110.3.........why would you ask that? (I thought the answer would have been assumed:roll: )

110.3 does not require any electrical product to be listed. It does require that a listed item is used as it is designed to be. :)

I guess you could run with 314.15 as well.

Notice that Article 314 includes hand holes but section 314.15 does not.

Look at 314.30 in the 2008 NEC.

It requires hand holes to be 'identified' but not listed.

Before the 2008 they did not even have to be identified.
 
Soooooooooooooo!:smile: Any speculation of why an inspector in 2002 would ahve required us to have them listed? At the time I was out of that loop, I just did the work, I really do not know the whole story. I know many AHJ's are on the listing bandwagon and I will confess I get some of it but definitely not the majority!

Thanks for the ed!
 
Many AHJ's require equipment to be listed. This falls under 110.2 and the definition of "approved".

That is likely the answer, but I would have tried fighting it on the basis the NFPA does not require the listing.
 
Just curious, it was previously stated that underground conduit is considered a wet location. I can't seem to find where the code states this other than in the commentary in the handbook under the definition of location, wet. Can someone tell me where the code specifically states that the interior of underground conduit is designated as a wet location?

Sorry around here all thhn is also listed as thwn. I get a little loose with the terminology. You know what happens when we assume. :smile:
