Copper and Aluminum Wires
Electrical Question: What is the Best Way to Splice Aluminum and Copper Electrical Wires?
I have a lamp with copper wiring that I want to install to my house which has aluminum wiring.
Can I do this, and if so, how? I have read that there are purple wire caps which have a gel inside which will allow the connection – is that correct?
