No torch needed

[resistance]

Can anyone recommend an underground splice kit for #12AWG--where no torch is required?

The 3m scotchcast kits are my favorite.
Sorry about the long url.

With standard heat shrink splice kits I use a heat gun. It takes a little longer than a torch, but there's less chance of burning the heat shrink and the sheathing of the wire.

Is this in a pipe or a pull box?

There is some kind of readily available goop that you can put on connections but the manufacturer has not/will not tell me if it is OK for "ground contact."
That 3m thing is quite a production.

I'll look into the 3M

this stuff is pretty neat, I have used it a couple times, It is pre-stretched oversized, with a plastic coil core, as you pull and uncoil it the rubber closes up on the wire really tight...

I use the self sealing UF splice kits, no mess, and trouble free installation.

Couple B-Caps filled with RTV silicone and a few wraps of Super 33.

Now you have my attention....you really do it that way?

No, not for a permanent repair. If it's a patch job until I can schedule trenching or whatever, I don't waste a splice kit. My way is legal, though.

I was a little scared at first myself.

I know of an electrical contractor that makes underground splices in UF by using wirenuts and pushing them into a paper cup full of silicone, I have followed behind him and made repairs on his repairs....

One of the silicon filled wire nuts is listed for direct burial.

You got that right! Don't mess up, there's no second chance, especially if the cables are already on the short side.

But on the plus side, it is also submersible and we have some that have been doing fine in chemically treated water for 2.5 years.

I have one of those that I use in class all of the time as an example that UL listing needs to be understood and interpreted.
The wire nuts are listed for direct burial, but the individual conductors of a UF cable assembly are not. The sheath of the UF is what is suitable for direct burial; once you remove the conductors from the sheath to make a splice, the conductors are not rated for direct burial. Even if they are rated for direct burial, they are not labeled so there is no way to know. The package that I have states that it is usable on "single conductor UF" only. I have never seen a single conductor UF, but according to 340.2 it may exist.

We used to make splices in 2400 v underground in conduit with a compression splice, scotch fill insulating putty, and #33.


If you stretch the scotchfill putty when you wrap it and stretch the 33 to half its width when you wrap it, and tape fron the thick part of the splice to the thin part,... I can't see anything gettin' in there.

Scotchfill is some pretty good stuff.

Well you should thank him for all the work! :grin:

Funny thing, I used this exact stuff just today to fix some #12 UF that met an excavator. Worked quite well, I'd definitely recommend 3M cold-shrink. My other favorite for temporary repairs is Scotch 130C splicing tape.
