Grounding Specifications
Ground Path Resistance 0.10 ohms Max.
Insulation Resistance 250K ohms Min.
Power Supply Requirements
The cooktop must be connected to a supply
circuit of the proper voltage and frequency as
specified on the rating plate. The rating plate is
located on the side of the component box. Wire
size must conform to the National Electrical
Code or the prevailing local code.

for a counter-mounted cooktop and not more
than two wall-mounted ovens – all supplied from
a single branch circuit and located in the same
room – shall be computed by adding the name-
plate ratings on the individual appliances and
treating this total as equivalent to one range.
Wiring
Built-in power leads are U.L. approved for con-
nection to larger gauge household wiring. The
insulation of these leads is rated at temperatures
much higher than the temperature rating of house-
hold wiring. The current carrying capacity of a
conductor is governed by the temperature rating
of the insulation around the wire rather than the
wire gauge alone.
WARNING: Improper connection of aluminum
house wiring to these copper leads can result in a
serious problem. Use only connectors designed
for joining copper to aluminum and follow the
manufacturer's recommended procedure closely.
