ELECTRICAL CONNECTION
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.
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.
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.
•This appliance must be supplied with the proper voltage and frequency,
and connected to an individual, properly grounded, 40 amp (minimum)
branch circuit protected by a circuit breaker or time-delay fuse.
•A single-phase (split-phase), 3-wire or 4-wire, AC 120/208 Volt or 120/240
Volt 60 hertz electrical system must be used. It is the personal
responsibility of the range owner to provide the correct electrical service
for this range.
•Effective January 1, 1996, the National Electrical Code requires that new
construction (not existing) utilize a 4-conductor connection to an electric
range. When installing an electric range in new construction, mobile
home, recreational vehicle, or an area where local codes prohibit
grounding through the neutral conductor.
•This range may be connected by means of a conduit or power cord.
•A range cord rated at 40 amps with 120/240 minimum volt range is
required. If a 50 amp range cord is used, it should be marked for use with
13/8" diameter connection openings. Care should be taken to center the
cable and strain relief within the knockout hole to keep the edge from
damaging the cable.
•Use only a 3-conductor or a 4-conductor UL-listed range cord. These
cords may be provided with ring terminals on wire and a strain relief
device.
•Allow 2 to 3 ft (61.0 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).
•The power supply cord and plug should not be modified. If it will not fit
the outlet, have a proper outlet installed by a qualified electrician.

14
•Using an extension cord to connect the power is prohibited. Connect the
power cord and plug directly.
•Wire sizes and connections must conform with the rating of the range.
•If using a GFI breaker, the ground wire must be installed correctly to
prevent breaker from tripping. Refer to latest edition of the NEC, NFPA
No. 70, available from the National Fire Protection Association.
•The wiring diagram is located on the back of the range.
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.
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.
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.
