Electrical Requirements
Electrical Requirements - U.S.A. Only
If codes permit and a separate ground wire is used, it is
recommended that a qualified electrical installer determine that
the ground path and wire gauge are in accordance with local
codes.
Do not use an extension cord.
Be sure that the electrical connection and wire size are adequate
and in conformance with the National Electrical Code, ANSI/
NFPA 70-latest edition and all local codes and ordinances.
A copy of the above code standards can be obtained from:
National Fire Protection Association

WARNING:
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. Check with a
qualified electrician or service technician if you are in doubt as to
whether the appliance is properly grounded. Do not modify the
power supply cord plug. If it will not fit the outlet, have a proper
outlet installed by a qualified electrician.
Electrical Connection
To properly install your range, you must determine the type of
electrical connection you will be using and follow the instructions
provided for it here.
■
Range must be connected to the proper electrical voltage
and frequency as specified on the model/serial rating
plate. The model/serial rating plate is located under the
storage drawer. See the installation instructions on how to
remove the storage drawer. Refer to the figures in “Product
Dimensions” in the “Location Requirements” section.
■
This range is manufactured with the neutral terminal
connected to the cabinet. Use a 3-wire, UL listed, 40- or
50-amp power supply cord (pigtail) (see the following Range
Rating chart). If local codes do not permit ground through
the neutral, use a 4-wire power supply cord rated at 250
volts, 40 or 50 amps and investigated for use with ranges.

*The NEC calculated load is less than the total connected
load listed on the model/serial rating plate.
**If connecting to a 50-amp circuit, use a 50-amp rated cord
with kit. For 50-amp rated cord kits, use kits that specify
use with a nominal 1³⁄
8
” (34.9 mm) diameter connection
opening.
■
A circuit breaker is recommended.
■
The range can be connected directly to the circuit breaker
box (or fused disconnect) through flexible or nonmetallic
sheathed, copper or aluminum cable. See the “Electrical
Connection - U.S.A. Only” section.
■
Allow 2 to 3 ft (61.0 cm to 91.4 cm) of slack in the line so that
the range can be moved if servicing is ever necessary.
■
A UL listed conduit connector must be provided at each end
of the power supply cable (at the range and at the junction
box).
■
Wire sizes and connections must conform with the rating of
the range.
■
The wiring diagram is located on the back of the range.
If connecting to a 4-wire system:
This range is manufactured with the ground connected to the
neutral by a link. The ground must be revised so the green
ground wire of the 4-wire power supply cord is connected to the
cabinet. See “Electrical Connection - U.S.A. Only” section.
Grounding through the neutral conductor is prohibited for new
branch-circuit installations (1996 NEC); mobile homes; and
recreational vehicles, or an area where local codes prohibit
grounding through the neutral conductor.
When a 4-wire receptacle of NEMA Type 14-50R is used, a
matching UL listed, 4-wire, 250-volt, 40- or 50-amp, range
power supply cord (pigtail) must be used. This cord contains
4 copper conductors with ring terminals or open-end spade
terminals with upturned ends, terminating in a NEMA Type 14-
50P plug on the supply end.
The fourth (grounding) conductor must be identified by a green
or green/yellow cover and the neutral conductor by a white
cover. Cord should be Type SRD or SRDT with a UL listed strain
relief and be at least 4 ft (1.22 m) long.
The minimum conductor sized for the copper 4-wire power cord
are:
40-amp circuit
2 No.-8 conductors
1 No.-10 white neutral
1 No.-8 green grounding
If connecting to a 3-wire system:
Local codes may permit the use of a UL listed, 3-wire, 250-volt,
40- or 50-amp range power supply cord (pigtail). This cord
contains 3 copper conductors with ring terminals or open-end
spade terminals with upturned ends, terminating in a NEMA Type
10-50P plug on the supply end. Connectors on the appliance
end must be provided at the point the power supply cord enters
the appliance. This uses a 3-wire receptacle of NEMA Type
10-50R.
