Ok to splice #10 wires in a jb I know you just use wire nuts. What about splicing 2/0, 3/0 etc. Split bolts etc??? It for tapping a feeder. Thanks.

You could :

Polaris or ilsco taps are the fastest to install and the easiest to work on in the future if you would need to get them apart and back together. Split bolts would work as well, it just takes a long time and multiple products to make up the insulation system on them correctly. Power blocks are a cleaner option than the ilsco or polaris taps, but it takes more space to mount them. The big advantage is that they don't move around since they're screwed fast so it's safer to put a meter on them when they're held stationary.

Ask the counter guy in the supply house for 750MCM wirenuts. They fit every size from 16ga to 750MCM.

Very handy, saves shelf space in the truck too.
