DOUBLE INSULATION
.... Double Insulation is a concept in safety, replacing the stan-
dard grounded supply system, in electric power tools. The
construction of adouble insqtated tool affords compatible
protection to aproperly grounded toot without the necessity
for using a grounded conductor. The double insulation
system eliminates the need for the usual three wire grounded
power cord and grounded supply system. Wherever there is
electric current in the tool there are two complete sets of
insulation to protect the user. All exposed metal parts'are
isolated from the internal metal motor components with pro-
tecting insulation. The lead wires, switch, etc. with their
•functional insulation have the added protection of non con-
ductive sleeving or housings to complete the double insula-
tion system.
