Default Splicing 500 MCM to #2

I have a job where I need to splicing some 2 AWG to 500MCM. I cant cut the 500 either. i have previously used piercing tap connectors for lack of something better. Are there other options out there?

I’m not a fan of insulation piercing connectors. I think good old-fashioned split bolts work great. The problem is that I don’t think they make one that could go from 500 to number two.

You can splice in a larger conductor and then use a set screw reducer to go down from that larger conductor to number two.

I’m just curious why you can’t cut the 500 and use a Polaris style connector?

If insulated taps, dist. blocks, insulating piercing taps are all out.....then I'd probably be looking at these:

I haven't used them, I've just seen them in the catalog when I was looking for something else. They have one listed for a 500mcm main with a #2 tap.

The giant red wire-nuts that look like a Solo cup?










Yeah, if somebody could just post a picture of a Solo cup, that'd be great.

I'm pretty sure you will run afoul of tap rules [or maybe not I don't have my book close] but you will need a large JB to get those kearneys tapped tightened and taped[ the 3 T's].If you do this, take your time and get those kearneys tight.

Depends what he's doing. We did a job that had 500 AL run 1100' on a 100A circuit and tapped a panel off partway out.

There are ones out there that will do 500 run with 2 tap.

I mean yeah if you have a crimp tool you could H or C tap it.


But there are split bolts that can do that sort of run and tap combo and you just need wrenches to do them.

I'm glad I read the replies before I jumped right in. That was the first thing that popped into my tiny little mind, what situation would this be acceptable in? Then, which ones wouldn't it be?

It's getting harder to find the info on the web sites, a lot of the manufacturer's web sites are more mobile friendly, they just don't contain the technical info you need any more

Would there be a problem with the tap rules? I'd have thought it's OK as long as the main is within 10' and probably at 25'.

Your'e right, I was thinking of a long mid-span tap in a pull C for some reason. Probably was confusing something Iv'e seen [I wouldn't do this]in my travels working on R-mix plants.

What about using the Polaris IPLD500-3? 3 ports, it accepts conductors from both sides, and handles 500MCM to #4.

Just cut the conductors, strip a little off each end, insert them into the connector, then insert the #2- Done. No having to insulate in tight spaces, and you can cut all the conductors at once to get the other ones out of your way as you work.
