10 INSTALLATION
This wall oven must be electrically grounded in
accordance with local codes or, in their absence,
with the National Electrical Code ANSI/NFPA
No.70- latest edition* in United States, or with CSA
Standard C22.1-1982 and C22.2 No.01982 (or latest
edition)**, Canadian Electrical Code, Part1, and all
local codes and ordinances.
All wiring should conform to Local and NEC codes.
This appliance requires a single-phase, 3 wire, A.C
120/208 V or 120/240 V 60 Hz electrical system.
Use only a 3-conductor or a 4-conductor UL - listed
cord with closed-loop terminals, open-end spade
lugs with upturned ends or similar termination. Do
not install the power cord without a strain relief.
A built-in oven can consume up to 7,800 W at 240
VAC. A 50 Amp circuit breaker with wire gauge #8
AWG must be used.
WARNING
• Do Not ground to a gas pipe.
• Do Not have a fuse in the neutral or grounding
circuit.
• A U.L.-listed conduit connector must be provided
at the junction box.
• The appliance must be hard wired (direct wired)
into an approved junction box. A plug and
receptacle is not permitted on these products.
• DO NOT shorten the flexible conduit. The
conduit connector must be securely attached to
the junction box and the flexible conduit must be
securely attached to the conduit connector. If
the flexible conduit will not fit within the
connector, do not install the oven until a
connector of the proper size is obtained.
NOTE
• The power leads supplied with the appliance are
UL, CSA recognized for connection to larger
gauge household wiring. The insulation of these
leads is rated at temperatures much higher than
the temperature rating of household wiring. The
current carrying capacity of the conductor is
governed by the wire gauge and the
temperature rating of the insulation around the
wire.
• You will need to purchase an appropriate
conduit connector to complete the connection of
the conduit to the junction box.

Making Electrical Connections

WARNING
• New branch-circuit installations (1996 NEC),
mobile homes, recreational vehicles, or
installations where local codes prohibit
grounding through the neutral conductor
require 4-wire branch-circuit connection.
• Improper connection of aluminum house wiring
to copper leads can result in an electrical hazard
or fire. Use only connectors designed for joining
copper to aluminum and follow the
manufacturer's recommended procedure
closely.
1
Turn off the circuit breaker or remove fuses to
the oven branch circuit.
2
With the oven positioned directly in front of
the cabinet opening, connect the flexible
conduit to the electrical junction box. Position
the conduit in such a manner that it will lie on
top of the oven in a natural loop when the
oven is installed.
3
If local codes permit connection of the frame
grounding conductor to the neutral (white)
wire, follow the instructions for a 3-wire circuit
connection.
4
If used in mobile homes or new construction,
or a recreational vehicle, or local codes do not
permit connection of the frame grounding
conductor to the neutral (white) wire, follow
the instructions for a 4-wire circuit
connection.
3-Wire Connection from Home Power
Supply
WARNING
• The middle (neutral or ground) wire, which is
white, of a 3-wire power cord or a 3-wire conduit
has to be connected to the middle post of the
main terminal block. The remaining two wires of
the power cord or conduit have to be connected
to the outside posts of the main terminal
