How do you connect a bare aluminium wire ground to a copper outlet?
What is the composition of the wire? Are the black and white wires copper or aluminum? If the black and white wires are copper, go ahead and change the outlets if you like…just connect the aluminum ground wire to the outlet as normal. If the black and white wires are aluminum LEAVE THE OUTLETS ALONE! You do not want to mess with the wiring if it is all aluminum, it gets brittle as well as forming aluminum oxide on the outside of the wire. Either of these things could start a fire. You also need to be concerned with dissimilar metal corrosion, not a good thing when you are playing with live wires. In the US, aluminum wiring was outlawed in the 1970’s for 110 volt circuits, and had been used less and less for about 20 years prior to that. The reason for this is that the aluminum wiring caused many house fires due to the aluminum oxide that formed on the wiring at the connections. Aluminum is a great conductor, better than copper, but aluminum oxide conducts electricity very poorly. Poo
the ground wire attaches to the box. take the alluminum out and use bare copper for the ground. please be sure you you the marrets that have the number 63 on the end as they are rated for copper to aluminum(hot and neutral) I like the fact that you are using the anti-oxidant that will make it safer. you can still buy the new style recepticals for aluminum but they are typically 2-3 times as much money.
