Were in the process of building our log home in washington state. Doing my usual thiknking ahead and to hard I bought our service cable ahead of time. We just had the footings spoted and I realized the cable is going to be 15′ to short. My question is does anybody have a source for a cable splice kit that will handle the 4/0 4/0 2/0 cable. It will be in conduit and under the house. I’ve heard splicing is legal but if this not correct I’d appreciate the real story. Thanks in advance, Skip

Keeping HVAC systems within the conditioned enclosure can be tough without a basement; one option is to use plenum trusses for the roof, which offer a space for equipment and ductwork.

here's a co. that offers splice and seal protection. It might be a mineralac sub company. The site is pretty simplistic, but I picked up a page of lit. at a show. Here's a link to the Shake n' Seal splice protection.

I made a similar mistake in a 750' run, no conduit, to an outbuilding. There's now a water-tight box buried with some large connectors in there. Don't know about a kit. I just used clamps and the right tape. Those clamps are bulky.
Was not inspected, no idea about that. Been in place 15 yrs, no problems.

Thanks Tom, were looking to some options, but have an electritian take care of this one.
300.15. The Code/Bible isn't very co-operative today. But I know for certain that you absolutely cannot have splices in conduit.
Basically, it says splices must be made in a box. Direct buried cable can be spliced.
For cable that thick, a split bolt or Polaris fitting should work. But, again, not in conduit. Also there are crimp sleeves available but those need a specialized crimper.

Why do people always mispronounce "debris"?
So if I read this correctly, if I bring the cable out of the conduit, bury the cable splice and re-install the cable in the conduit as it enters the subfloor I can should be OK, we may call an electritian to take care of this little problem. Thanls for the help. Skip
Assuming the splice would occur outdoors, the conduit would have to end up in a box of some sort. For instance, you could use one of those plastic, 1' X 2' boxes like irrigation people use.
Would it be too much to throw away the short cables and just get a 15' longer piece. Also you might consider using a "wire-stretcher". If you need instructions for making one, let me knoew.

Thanks Peter, we have it figureed out, the answer is using the box you suggested and splice the cable using polaris splice blocks. It will be in the crawl space out of harms way.
Thanks Skip
Cables can be spliced but there are restrictions. There are approved splices for direct buried cable and approved splices for overhead cable, and you can splice cables inside a junction box or handhole, but splicing cables inside a conduit is not allowed. Without being able to see exactly what your situation is it's hard to give specific advice, so you should probably find a licensed electrician who can come out and take a look in person.
Thanks Stuart, we were consideing having the splice done by a pro. Were trying to do most of the work ourselves but this be one for a real electrictian. Thanks again
Any splice or connections need to be accessible.
Go to HD and get a in-ground box, a open-bottom box with a heavy cover that's traffic rated if there is any chance of vehicle traffic, and head to the electrical supply house for a set of direct-burial Polaris splice blocks.
Be sure to follow the directions and kill the power before messing with it.
Thanks, thats the best advice yet, the box will be in the crawl space so chance of traffic.
Thanks again, Skip
