4 Gauge to 0 Gauge input (output)

[jragusa 10+ year member]

Hey, I'm in the process of upgrading my big 3. But I've ran into a considerably small problem.

I have this

on my positive battery terminal. It has an output for 4 gauge, 0 gauge and (2) for 8 gauge.

Problem is I'm using the 4 gauge for one amp and the new cable I have for the big 3 (positive to alternator) is also a 4 gauge. But there is only one 4 gauge output. I've heard of wire reducers (0 gauge to 4 gauge) but how would I go about securely fitting the 4 gauge wire in the 0 gauge output?

In short: Do they make anything for a 4 gauge cable to fit into a 0 gauge socket?

yes, they are a collar with a hole in the top. reduces inside diameter and lets set screw come through. but i've only seen them come with terminals/holders. i haven't seen them sold separately.

you could strip 2x as much 4 awg and fold it on itself. you want to fill the entire cavity so you don't have arcing. you want as much contact area as possible. just be careful so no bare copper strands are visible. the wire insulation needs to seat just inside the terminal.
