6.6. SERVICING OF DOUBLE-INSULATED APPLIANCES
A double-insulated appliance is marked with one or more of the following: The words “DOUBLE
INSULATION” or “DOUBLE INSULATED” or the double insulation symbol (square within a
square)
In a double-insulated appliance, two systems of insulation are provided instead of grounding. No
grounding means is provided on a double-insulated appliance, nor should a means for
grounding be added to the appliance. Servicing a double-insulated appliance requires extreme
care and knowledge of the system, and should be done only by qualified service personnel.
Replacement parts for a double-insulated appliance must be identical to the parts they replace.
