Hi,
i’m installing ground mount solar and running 4 awg aluminum wire. One of my strings ran short, so I connected more aluminum wire using a copper butt connector and the heat shrink tube. I was just reading that you should not combine aluminum and copper.
Is it really a big deal? I already pulled the wire through my conduit. Of course I can pull it back out and replace it with an aluminum butt connector – but that’s a pain.
thanks in advance for any help
Steve
