SERVICING OF DOUBLE-
INSULATED PRODUCTS
In a double-insulated product, two systems of insula-
tion are provided instead of grounding. No grounding
means is provided on a double-insulated product, nor
is a means for grounding to be added to the product.
Servicing a double-insulated product requires extreme
care and knowledge of the system, and is to be done
only by qualified service personnel. Replacement parts
for a double-insulated product must be identical to the
parts they replace. A double-insulated product is
marked with the words “
DOUBLE INSULATION
” or
“
DOUBLE INSULATED
.” The symbol is also able to
be marked on the product.
