plugged into the ungrounded receptacle and its wire connected
to the receptacle mounting screw. With this wire completing the
ground, the appliance cord plug can be plugged into the adapter
and be electrically grounded.
CAUTION: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
