[RE-wrenches] Butt End Connector Warning

[drake.chamberlin at redwoodalliance.org]

Our electrical supplier seamlessly transitioned from crimp on butt end 
connectors, that were listed for CU and AL, to unmarked ones that were 
approved for copper only.

I became concerned since there was no marking. Calling two electrical 
suppliers, the guys at the counter had to look up the device to learn 
that they were listed for copper only. Talking to one of the counter 
guys, he agreed that electricians were probably using these for 
aluminum.

Since the barrels will be insulated, it is not likely that inspectors 
will see them. The connectors are made of coated copper. I wonder how 
much of a problem this will be.
