Proper splice connectors

[timmed]

Greetings all - I need to splice some 4awg copper to 6awg. This is a junction that I inherited when I bought this home, I would have done it differently if I was running it from scratch. The junction connects one sub-panel to another, both in separate buildings.

Anyway, considering the options I have and the amount of money I want to spend, do you have any preferences for what kind of connector you would choose? It will be in a junction box indoors, dry location. Those copper butt splices are rated for 4awg wire, made of copper but I can't find any voltage ratings for them.

Thoughts?

I used these just the other day for a j-box. NSI IT-4C

My supplier sells them for $12.88.

IBTL.

The moderators don't allow us to help DIYers. They are mean that way.

There are all kinds of options for connecting #6 to #4.

Note that the crimp type barrel connectors would require an appropriate crimping tool with the correct die for the connector. the tool will be more than the connectors.

No voltage rating on the bare items because there is no insulation value related to them, it is what you cover them with that will be subjected to a voltage differential.

Thanks gentlemen, apologize I was not aware that I wasn't supposed to ask for DIY advice here. I ended up ordering a few polaris connectors from Home Depot. Had to pay a little more than $12.88, but not too bad.
