Step 9
Before Making Electrical Connections
Note to Electrician: The power leads supplied
with this appliance are U. L. recognized for
connection to large gauge household wiring. The
insulation of these leads is rated at temperatures
much higher than the temperature rating of
household wiring. The current carrying capacity
of a conductor is governed by the wire gauge
and also the temperature rating of the insulation
around the wire.
Aluminum Wiring—WARNING: IMPROPER
CONNECTION OF ALUMINUM HOUSE
WIRING TO THE COPPER LEADS CAN
RESULT IN SERIOUS PROBLEMS.
Attach copper wires to aluminum wiring using
special connectors designed and U. L. listed for
joining copper to aluminum. Follow the
connector manufacturer’s recommended
procedure closely.
