What’s wrong with aluminium wiring?
Nothing really, if it’s properly maintained. There was a copper shortage between the 1950’s and 1970’s. So, aluminium wiring was used in most houses built or renovated at that time. Builders used a larger gauge aluminium wire so that it could safely carry the same amount of current as copper.
But, there are some problems with aluminium wire.
After the 1970’s builders went back to using copper. Today, electrical appliances, lighting fixtures and other electrical devices are wired with copper. So, what’s the problem? When you mix copper and aluminium it can start a fire!
If your house is wired with aluminium, you have to use switches receptacles and fixtures that are made for aluminium. If you can’t find these, call an electrician.
Mike Smith owns a house that was built in 1968. He would like to turn a part of his unfinished basement in to a recreation room. The room is already wired with aluminium. Mike would like to add 2 new receptacles and a new light fixture in his room. He calls your company to do the work.
When you arrive, the electrician tells you to run new copper wire from the circuit box to the places in the room where the receptacles and light will be. Why do you think electrician wants all new wire?
