Hi, I am looking for a spec recommendation on a insulated ( non compression) splice block that is rated for Aluminum to Copper Connections for typical Risers. The intornetz is giving me a tumor trying to find a suitable device. I am basically looking to extend a old 3 Wire Aluminum Feeder. Splice will be made inside a JB where the old panel was.

Any input is appreciated.

I would think that any Polaris / NSI connector would work for wires over #8.

Polaris connector would be my choice.

I pretty much the same pages as two guys mention above get Polaris connector they are pretty easy to use it and there is few verison you can use depending on which way you run the conductors in the Jbox.

A reminder here becarefull with sizing the junction box don't get too small a jbox.

Merci,Marc

Thanks for the responses
