I recently purchased a new home wired with aluminum wire. The house has all Decora switches and receptacles. These are not CO/ALR rated. I have checked all the connections. They are tight, and there are no signs of burning or arcing in the boxes. These switches and receptacles were replaced over 10 years ago according to the previous owner. Should I leave things alone and just continue to check the connections once a year (the previous owner never checked the connections)?

Many thanks.

 

I'll go this way:Worked with a guy said he had to get right home.Asked why? He said so he is there to see where the fire starts in a wall plug so he can put it out. Said he has to get around to pulling all that aluminum wire out someday. ED

 

Well you have entered the world of uncertainty. If the question is.....is my aluminum wiring up to code? then it becomes less controversal. First no 14 awg wire. Second 12 awg must have overcurrent protection of 15 amps not 20 amps like copper. This makes aluminum romex unsuitable for small appliance circuits in kitchens since 20 amp circuits are required there. 3rd, switches and receptacles directly (Not pigtailed with copper) connected to aluminum wire must be CO/ALR rated.
As for making it safer, upgrading and repair you come to a whole bunch of opinions and controversy. I suggest you read the following link
