Duplex Outlets - Fire hazard - TVI

"Wire Nuts"

> We had (all) aluminum wiring in our house in Houston. The fix there was
> "pigtail" sockets. They had steel pigtails permanently attached to the
> sockets which were, in turn, mated to the aluminum wires with wire nuts,
> those plastic, conical-shaped thingies that electricians use to tie two
> wires together. We lived in that house for 16+ years without any problems,
> and that included a 220 vac line to my amp.
