I have a length of 6/4 Aluminum cable that I'd like to use as a 40 amp feeder to a small sub panel in my attached garage. I can get a picture of the cable later today but one thing I do remember about the cable is that it does not have the ground wrap around all the conductors, its un-insulated and is twisted all by itself.

Question is, can I use this through the wall and run to a sub panel in my garage? I already know everything there is to connecting a subpanel, I am just questioning the use of the aluminum cable I have.

Edit: its type SE/SER cable, see the attached picture....

Knock yourself out. This type of cable is used like this all the time. Just do yourself a favor and use an antioxidant compound on the connections.

Agreed, SER AL (service entrance---round type) may likely be the most common sub-panel feeder for 40 and above amps used by electricians with nm-b being the most commonly used by do it yourselfers up to 60 amps. You cannot go underground with it though. SER sounds like just the ticket for your application.

Awesome, got it from a buddy who's store closed down and got some electrical stuff for cheap. Just need a small sub panel for outlets to run some tools, air compressor, possibly a welder down the road (small one). This run will be a short run (probably about 50 feet) and would be easy to change out in the future if needs change. Thanks!
