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"
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.

(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- 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.
