#2 issue is nobody is stocking Al compatible marrett connectors either I cant understand why a contractor cannot get these items easily, I hear guys are just stuffing the marrette with nolux and assuming thats correct.
Doug, We just redid a commercial property that was all aluminum wireing. You can order all switches and receptacles at hamden zimmerman electrical supply here in springfield, mass. They will also ship them to you. They are pricey and they also carry the AL/CU wirenuts. Good luck and remember they are pricey.
When I run into AL/CU stuff, I won't do the job anymore unless the client agrees to a changeover to CU only. I know this may not work well in Kelowna for some retired and cantankerous old farts that are trying to save a buck or two.
The reason I changed to CU only was exactly the problem you are running into out there in CYKA. It just got to be too much of a hassle trying to chase down and stock CU/AL parts, even the compatible wire nuts you can't find.
When I priced out the difference in using CU/AL compatible components to that of changing to CU only it only made a difference of about $500.00 more in labour in most cases, to change to CU for a typical remodel and, in my humble opinion, tends to be a lot safer as the components age.
As to stuffing the Marrett's with nolux - sometimes I have seen that stuff "dry out" after as little as ten years and the connectors gets cooked a nice toasty brown colour. It shows up right away in the infra-red scan like a beacon at an airport because of the heat the CU/AL interface generates after the nolux has dissipated.
Hope that helps. Cheers from Edmonton.
