proper splicing for larger gauge wires

simancoSeptember 28, 2013

Hello all,

What would be the proper way to splice 6 gauge to 6 gauge or 4 gauge to 4 gauge wires?

The application will be a hard-wired high-amperage range. I've not determined the exact specs yet but it'll be 60 or 70 amps.

Thanks!
Jim

Split bolts would be one way. They also make terminal blocks (like little 2 screw bus bars).

For the homeowner, split-bolts offer (arguably) the best connection. The split-bolt will be marked with the wire types and sizes for which it is suitable. If time permits, install and tighten the split-bolt one day, then retighten it the next day and then insulate it.

"nstall and tighten the split-bolt one day, then retighten it the next day...."

What is the reason for going back to retighten it? A little thermal cycling or something that I can't think of?

Just use these and forget it. This particular one accepts up to #4awg. Also search polaris connector.

Here is a link that might be useful: NSI connector
