[See "Four-wire electrical connection"
section. Panel C.)
When a d-wire receptacle
of NEMA
type 14.50R is used (See Figure 2). a

range power supply cord
(pIgtail) must be used. This cord
contains four copper
conductors

conductor
must be
Lsentified by a green or green/yellow
cover and the neutral conductor
by a
white cover. Cord should be Type SRD
or SRDT with a U.L.-listed strain relief
and be a least four feet long.
The MINIMUM conductor sizes for the
copper 4-wire power cord are:
547 ampere circuit
