I have been asked to bid a job to evaluate the condition of the aluminum wiring in two multi tenant apartment buildings. My first gut instinct is to say no due to the liability issues. Is there a proper way to go about this evaluation. One fellow electrician said you have to remove every device and check the connections and torque on eack screw/lug ect.
Ideas? HELP!
I have a 'rule'....
Go by my first feeling!

Bid it at T&M, in phases if they want..
CYA, Mike..
Not only do you have to check each device, but you are going to have to make sure each and every device is compatible with aluminum.
I went through this last year and ended up having to put a copper jumper between each aluminum conductor and the device terminals using wire connectors with a CU/AL rating. My supplier doesn't carry any devices that are rated for AL but was able to get me the CU/AL wire connectors. I did this job at T&M.
I saw in a new house being built, they used aluminum wiring for a 50a 240v circuit. Is this still used in the larger size wire? Is it legal? I know it for range cable, feeders etc., a long time after the 70's when they used the aluminum #12 general lighting circuits for homes.
