I recentley replaced my stove and found that the existing wire was #4
aluminum 3 wire + 1 uninsulated ground. When changing the stove I had
to also change the outlet from a 3 wire to 4 wire outlet, but found I
did not have enough slack in the existing to make the new connections.
As a result, I cut open the wall and put a splice box (exposed) and
spliced in a pigtail of #8 copper. I made the splices using AL/CU
split bolts and taped them up real good. Before sliding the stove
back I ran everything on full for 10 minutes and checked all
connections - they were all cool. I also verified ground and neutral
were not open.
Given all the issues with aluminum wire I will be replacing this very
soon, but would like some feedback on this temp installation. Is it
safe for the short term? I DID NOT use antioxidant on the aluminum
wire at the splices.
Thanks in advance.
