Connecting The Range To An Electrical Supply - Whirlpool 4322525 Manual

IMPORTANT: Use a new 40-ampere power
supply cord. Local codes may permit the use
of a U.L.-listed, 250-volt, 40-ampere range
power supply cord (pigtail). The power supply
cord should be Type SRD or SRDT, and be at
least 4-feet long. The wires that connect to the
range must end with ring terminals. A
cm), U.L.-listed strain relief must be installed
where the power supply cord connects to the
range (see Figure 2-3).

The power supply cord must have three No.-10
copper wires to match a 3-wire receptacle of NEMA
Type 10-50R. (See Figure 2-4).

This range is manufactured with ground con-
nected to cabinet for mobile home, or other 4-
wire installations. The ground must be revised
so the green grounding wire of the four-wire
power cord is connected to the cabinet.
For a 4-wire receptacle (NEMA Type 14-50R,
shown in Figure 2-4), a matching U.L.-listed,
4-wire, 250-volt, 40-ampere, range power sup-
ply cord (pigtail) must be used. This cord con-
tains four copper conductors with ring termi-
nals on the appliance end, and terminates in a
NEMA Type 14-50P plug on the supply end.
The fourth (grounding) conductor must be iden-
tified 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
The range can also be connected directly to a
fused disconnect, or to a circuit breaker box,
through flexible, armored or nonmetallic
sheathed, copper cable (with a grounding wire).
Do not use 2-wire cable with a bare grounding
wire. All current-carrying wires must be insu-
lated. A U.L.-listed conduit connector must be
provided at each end of the power supply cord
(at the appliance and at the junction box). USE
ONLY 8-GAUGE SOLID COPPER WIRE. DO
NOT USE ALUMINUM WIRE. Allow 2- or 3-
feet of slack in the line so the range can be
moved if servicing is ever necessary.
IMPORTANT: The metal chassis of the range
must be earth-grounded so that the control
panel will operate. If the chassis is not earth-
grounded, none of the keypads will operate.
Check with a qualified electrician if you are in
doubt as to whether the range is earth-
grounded.
