ELECTRICAL SUPPLY REQUIREMENTS

WARNING
Electrical Shock Hazard
An electrical ground is required on this appli-
ance.
Use only a new power supply cord kit rated at
250-volts, 40-amperes and rated for use with
ranges. Do not reuse an old power supply cord.
Do not modify the power supply cord plug. If it
does not fit the outlet, have a proper outlet
installed by a qualified electrician.
Do Not use an extension cord with this appli-
ance.
If a cold water pipe is interrupted by plastic,
nonmetallic gaskets, or other insulating materi-
als, do not use for grounding.
Do not ground to a gas pipe.
Do not use a fuse in the neutral or grounding
circuit. It could result in an electrical shock.
Check with a qualified electrician if you are in
doubt as to whether the appliance is properly
grounded.
Failure to follow these instructions could result in
serious injury or death.
GENERAL
If codes permit, and a separate grounding wire is
used, it is recommended that a qualified electrician
determine that the grounding path is adequate.
The following information applies to the electric
range wiring:
• A 3- or 4-wire, single phase, 120/240-volt, 60
Hz, AC-only electrical supply, (or a 3- or 4-wire
120/208-volt, if specified on the model/serial
rating plate), is required on a separate 40-am-
pere circuit, fused on both sides of the line. A time-
delay fuse, or circuit breaker, is recommended.
The fuse must be sized as per local codes in
accordance with the electrical rating of the appli-
ance specified on the model/serial rating plate,
which is located behind the storage door on the
left side of the oven frame.
• The range must be connected with copper
wire only.
• Local codes may permit the use of a U.L.-
listed, 250-volt, 40-ampere range power sup-
ply cord (pigtail). This cord contains three #10
copper wires, and matches a 3-wire recep-
tacle of NEMA-type 10-50R. Connectors on
the appliance end must be provided at the
point the power supply cord enters the appli-
ance.
• The range should be connected directly to the
fused disconnect (or circuit breaker) through
flexible, armored, or nonmetallic sheathed,
copper cable. The flexible, armored cable that
extends from the appliance should be con-
nected directly to the junction box.
• Locate the junction box to allow as much slack
as possible between the junction box and the
appliance so that the appliance can be moved
if servicing is ever necessary. Do not cut the
conduit.
• A U.L.-listed,
provided at the junction box.
• Wire sizes (copper wire only) and connec-
tions must conform with the rating of the
appliance, which is 40-amperes.
• A wiring diagram is located in the "Tech Tips"
(Section 5) of this manual.
4-WIRE SYSTEM
This range is manufactured with ground connected
to cabinet for mobile home, or other 4-wire instal-
lations. The ground must be revised so the green
grounding wire of the four-wire power cord is con-
nected to the cabinet.
For a 4-wire receptacle (NEMA Type 14-50R,
shown below), a matching U.L.-listed, 4-wire, 250-
volt, 40-ampere, range power supply cord (pigtail)
must be used. This cord contains four copper
conductors with ring terminals on the appliance
end, and terminates in a NEMA Type 14-50P plug
on the supply end. The fourth (grounding) conduc-
tor must be identified by a green, or green/yellow
cover, and the neutral conductor by a white cover.
The cord should be Type SRD or SRDT with a U.L.-
listed strain relief, and be at least 4-feet long.
The MINIMUM conductor sizes for the copper
4-wire power supply cord are:
• 40-ampere circuit
• 2) #8 conductors
• 1) #10 white neutral
• 1) #8 green grounding
