Re: Connecting new copper wire to old aluminum wire

Thank you for your reply. My mom's first husband was electrocuted so she has pounded a healthy respect for electricity into us so even if I know that the juice does not make it to the light, I always have to ask and ask again.

Is the wire in question aluminum?
Depending on the type of wire used during the original instillation, it might just have been coated with Tin{?} over copper.
Just a thought.....:cool:
If it is indeed aluminum, follow the advise posted above and you will not go wrong.....

Interesting, it looks like the wire is copper with some sort of plating. So now what? Do I treat this as traditional copper wire and just tap into it?

It seems like my options are to either change out the wiring at the point it enters the sun porch or tap into another circuit where the wiring has already been updated, then cap off the old wiring inside the wall, then leave a access point. The problem with this is that there may already be too many circuits on the new wiring’s breaker. So you know I will be replacing 3 or 4 plugs.

Tinned copper is handle just like regular copper wiring. There is no aluminum involved.

Alumiconn I believe they are available at Lowe's and possibly HomeDepot. If there is no current flowing (switched off) there should be no problem.

Ernie I believe the time line was from about 65 to 74 with most of the problems with the Al wire used before 72.

Still have yet to see Al in residential use. Just lucky, I guess.
