Basically the owner talked to the builder as if I was trying to use inferior materials in his house....and it really
burned my butt. He had called a electrician buddy of his and was told never to use aluminum wire in a house. I started to ask him what the dudes phone # was.....

I wire these homes and additions mostly on a sq. ft. basis and this is the first time an issue like this has come up.
Copper wire is the better alternative.....bits the price of the big cable thats ridiculous...
