Handhole enclosures

[codeunderstanding]

In reading 300.15L for hand holes it says you can only use where a qualified person would access it. So if you had a service lateral go bad and you did a underground splice kit in to repair it you could not use a handhole to put the splice in to get access to it if the splice went bad again. I think you would just have make the splice and bury it and hope for the best according to 300.15.

Or you could a splice kit listed for direct burial ~ 300.5(E)

Read that again. Its talking about a box not being required in a hand hole where ONLY qualified persons have access. Read 314.30(C). No box required here either. Hand hole required? Yes.

I guess OP wasn't talking conduit.

I see what you're saying Chris...existing HH had a NFG conductor in it.

These are 4/0 4/0 2/0 urd cables.

So you could put one of those handholes in on a residential setting?

If the cables are direct burial cables, using a listed direct burial splice kit frees you from the handhole requirement.

We meet POCO at hand holes here all the time. Including res.

This is an Ilsco model (I didn't look for specifics for URD)

I prefer the 3M version...once that resin hardens, that splice isn't going anywhere.

"if you had a service lateral go bad and you did a underground splice kit in to repair it "

My question is, does the utility own the lateral, or the property owner?

Some of the utilities we work with, they want the cable replaced, not repaired. That may not be the case in your area.

Thanks for the links. But it makes me wonder how you might use them. I'm not familiar with direct burial service lateral cables. If one got damaged I would assume you would have to peel the jacket back and make your splice. UL approval gone? Or is it just a twisted tri-plex for direct burial?

Not the best pictures...

I don't think so...if that were the case, everytime a cable was opened for termination or splicing the UL listed would be questioned.

Whenever you remove a cables jacket/insulation you must replace it an equivalent product...(110.7; 110.14(B); et al)

In the case of Romex/AC, etc...it's a wirenut....although I recall a thread about nicked Romax being repairable with tape....all the way up to your MV cables and your layers of semi-conc, di-electric, etc (I've never done a HV cable, so I don't know anything about them).
