step 1
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 are 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.
