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.
