3-Wire Lead Connection
This appliance is manufactured ready to install with a
supplied 4-wire cord set with plug attached to the
appliance. However, where local codes and ordinances
permit grounding through neutral, and conversion of supply
to 4-wire is impractical, the unit may be connected to the
power supply with a Listed (UL, CSA, ...) 3-POLE, 3-
CONDUCTOR cord kit rated 125/250 VOLTS, 50
AMPERES DEDICATED CIRCUIT, and marked for use
with ranges.
If a 3-wire power supply connection must be used, the 4-
wire cord set must be removed from the terminal block. It is
the responsibility of the installer to provide the proper wiring
components (cord, wires, etc.) and complete the electrical
connection as dictated by local codes and ordinances, and/
or the National Electrical Code.
The cord kit must be attached to the range back panel with
a strain relief which will fit a 1" (25.4 mm) diameter hole. If
not already equipped, the cord must also have 1/4'' (6 mm)
faston closed-loop lugs attached to the free ends of the
individual conductors, preferably soldered in place.
1. Locate the terminal block on the rear of the unit and
remove cover.

(25.4 mm) diameter hole in the back panel located
below the terminal block (see Figure 11). Route wires
up through strain relief.
