Electrical Requirements - U.s.a. Only - Whirlpool GY398LXP Mode D'emploi

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.
If codes permit and a separate ground wire is used, it is
recommended that a qualified electrician determine that the
ground path is adequate.
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,
One Batterymarch Park,

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 number rating
plate. (The model/serial number rating plate is located on the
oven frame behind the storage drawer panel.)
When a 4-wire or 3-wire, single phase 120/240 volt, 60 Hz,
AC only electrical supply is available, a 50-amp maximum
circuit protection is required (or, if specified on the model/
serial rating plate, when a 4-wire or 3-wire single phase
120/208 volt 60 Hz, AC only electrical supply is available, a
40-amp maximum circuit protection is required), fused on
both sides of the line.
A time-delay fuse or circuit breaker is recommended.
The range can be connected directly to the fused disconnect
(or circuit breaker box) through flexible, armored or
nonmetallic sheathed, copper or aluminum cable. See
"Electrical Connection."
Allow 2 to 3 ft 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 (40 amps).
The wiring diagram is located on the underside of the storage
drawer or below the warming drawer in a clear plastic bag.

Electrical Requirements - U.S.A. Only

If connecting to a 4-wire system:
This range is manufactured with the ground connected to the
cabinet. 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."
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-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 14-50R 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.
4-wire receptacle (14-50R)
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-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.
