Bidding a job to upgrade a all aluminum wire home. Any suggestions on what kind of connecters to pigtail all the outlets and switches? I checked with my supply house and they had those purple wire nuts with no-lox in them for $1.79 each. Is there a better way to go?
Thanks for any input,

The wire nuts with Noalox in in them is the best way I no of. You should be able to find a better price than $1.79 ea. Are you sure that wasn't for a pack of 8 or 10? I know you can buy them in a larger container.

This doesn't sound like much of an upgrade. Changing the devices and leaving the wiring is just a bandaid approach. I wouldn't touch this one unless they were willing to go with new wiring.

The only ones i know is the wire nut that is from IDEAL and is about $3.80 for two @ Home Depot. I usually charge about $20-25 per device if it is aluminum wiring.

Be careful with the purple wire nuts. The CPSC considers them to be for tempory use only. They have a bad habit of heating up and burning. AMP corp. makes a crimp on connector that can't be beat, however, you must buy the rights to your area and lease the crimp tool from them. Also, they are the only soarce for the connectors. I won't touch an AL. job unless it's a total rewire.

Electricmanscott,

I can't see replacing the whole wiring system. I don't see any problem with the aluminum wire runs itself, the problem is at the connections. Getting the right connection with copper wire should take care of the problem.. Am I wrong?

I have used the Purple wire nuts and feel comfortable with them. Read the instructions carefully, and be prepared to encounter broken wires. The job could easily escalate.

Since it is not legal to make splices in the panel, then nothing is done to change the aluminum connections at the breakers.. correct?

Most breakers I have seen are listed for use with AL or copper wires.
