How to Splice 4 awg to a 12 awg

[Sevo]

I am now in the process of wiring up my converter and can't find any splicers that would go from 4 awg to 12. I am tring to wire my amp and my battery. I have 4 AWG coming from the battery to the converter. The converter is 10 or 12 AWG. To my amp I also have 4 AWG and need to tie that into the converter as well. It to is a 10 or 12 AWG.

I was thinking of just getting a Gardner Bender HSB-28 Butt Splice Kit (http://www.amazon.com/Gardner-Bender-HS ... m_sbs_hi_1) The 4 AWG will fit perfectly but the 10 AWG will be very loose in that. Will this work?

Any ideas are greatly appreciated

Thanks

Not very pretty but how about some ring connectors like you'd use to ground to a frame and a bolt to hold them together and tape it up. they make them with 1/4" holes for both sizes of wire.

Why not use a split bolt, not as neat but effective. a Tyco CPGI-GELWRAP-18/4-200UL will als. work and be a good bit more compact

Thank you for the fast reply...

I thought about using one of those. I was unsure if that would work?

I may give that a try

I just used a crimp sleeve on the same size wire a couple of hours ago. Will probably use liquid electrical tape on the connection tomorrow if
it not raining.

Where did you get the #4 crimp sleeve?

sLowe's here had a mixed pack with 1/4 and #4 here. Any welding supply or old timey hardware store probably has them too.

This is a nice way to proceed, That setscrew buttsplice allows easy reconfiguring if needed and is compact and neat over a splitbolt, and no special crimper is required.

Anyway as it seems your 10awg is too small, you could place two 10awg wires side by side into the connector. See if that will tighten up.
If that becomes now too big to fit into the connector, Perhaps the 10awg and a bit of 12awg or 14awg for example...
If that will work, you could leave the 'extra' wire very short as it functions as a shim if you understand. Or leave it somewhat longer and it makes a handy place to connect future expansion of your electrical system.

Legal disclaimer,,,
In a workplace environment, this doubling trick maybe not 'legal' unless the connector in question is listed to be compatible with this combination of conductors.
Not something I would fuss over on a thing building oneself, So long as the doubled connections can be solidly tight and properly
insulated.

Sounds like great fun,,,
