is this suitable for 10 gauge wire

Yes, it can work with 10 gauge wire. Cables Diameters: 4-8mm / 0.16-0.31".

What is the internal dimensions?

I dont have one in front of me, but i used them to splice underground low voltage lights. there was plenty of room to make the straight splice through on the set screw insulated terminals it comes with , then push the wires back out so all you are left with is straight wires and no slack. silicone both ends for added protection and it works great. Not sure how big your needing, but my guess would be i could see 14-uf max . Possibly 12-2 , but i would have to test one first.Hope it helps
