Called to a house for a second option on the electrical. They just bought the house and have not moved in. Split level ranch garage underneath, walk into a nice finished family room all finished space. The house was built in 64 I think and has from what I can tell all original circuits are al. with a ground. In a few areas the kitchen has been upgraded. His question to me was should the house be rewired? I was the second electrician to see the house. The home inspector did note the al. at the panel.What do you think? should the house be rewired or left as is? I told him about arc faults, that could be used for all the al. ckts. There around 7-8. The first electrician said he thinks about 95% is al. and recommends rewire.
