ELECTRICAL CONNECTIONS
(Not used for Canadian
Installations)
This range can be connected directly to the
fused disconnect, or circuit breaker box, through
flexible, armored, or nonmetallic sheathed,
copper cable with a grounding wire. Allow two
to three feet of slack in the line so that it can be
moved if servicing is ever necessary.
A U.L.-listed conduit connector must be pro-
vided at each end of the power supply cable at
the range, and at the junction box.
Remove the terminal block cover located on
the back of the range.

following the instructions under the "Power
Supply Cord Connection," (page 2-3), or the
"Direct Wire Connection" (page 2-5).

4-Wire Electrical System
This range is manufactured with the ground
connected to the cabinet. The ground must be
revised so that the green grounding wire of the
4-wire power supply cord is connected to the
cabinet (refer to the "4-wire Electrical Connec-
tion" section).
4-Wire
Receptacle
14-50R
When a 4-wire receptacle of NEMA type 14-
50R is used, 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 at the appliance end, terminated
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 four
feet long.
The minimum conductor sizes for the copper
4-wire power cord are:
(2) #8 conductors
(1) #10 white neutral
(1) #8 green grounding
3-Wire Electrical System
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 three-wire recep-
tacle of NEMA Type 10-50R.
