inserted in a socket outlet with a
protective earth contact. Do not negate
the protective action by using an
extension power cord without a
protective grounding conductor.
Grounding one conductor of a
two-conductor outlet is not sufficient

connected to the earth terminal of the
power source.
Whenever it is likely that the ground
protection is impaired, you must make
