[R-390] Some progress

Sun, 5 Jan 2003 12:06:03 -0500

Well, maybe Joe can expand on this, but I believe aluminum wiring
is OK if done right.  That means using devices designed for aluminum wiring
and
using the right compound on the connections.  I think most electrical
services use
an aluminum feed from the pole to the panel.  The busses in the panels on
many
services are aluminum.  And the electrical inspector will want to see a
proper
compound on the service connections.
