Electrical Connection - Whirlpool COMMERCIAL DRYERS Installation Instructions Manual

ELECTRICAL REQUIREMENTS
OBSERVE ALL GOVERNING CODES AND ORDINANCES
A three-wire or four-wire single phase 120/240 volt
60 Hz AC only electrical supply (or three-wire or
four-wire 120/208 volt if specified on nameplate) is
required on a separate 30 ampere circuit, fused on
both sides of the line (time-delay fuse or circuit
breaker is recommended). Do not fuse neutral.
THE DRYER MUST BE CONNECTED TO COP-
PER WIRE ONLY. Aluminum wire must not be
used at the dryer appliance terminal block, to avoid
potentially unsatisfactory connections.
Local codes may permit the use of a flexible type
30 ampere power supply cord (pigtail) with no
smaller than #lO copper wire to match three-wire
receptacle of NEMA Type lo-30R shown in Fig. 7.
A suitable strain relief must be provided at the point
the power supply cord enters the appliance.
The appliance may be connected directly to the
fused disconnect (or circuit breaker) box through
flexible armored or non-metallic sheathed copper
cable. Allow two or three feet of slack in the line
between the wall and the appliance so that it can
be moved if servicing is ever necessary. A suitable
strain relief must be provided at each end of the
power supply cord (at the appliance and at the
junction box). Wire sizes (COPPER WIRE ONLY)
and connections must conform with the rating of
the appliance (30 amperes). Do not use an extension
cord.
CAUTION: For mobile home installations, the ap-
pliance wiring must be revised: the appliance
frame must not be connected to the neutral terminal,
but must be connected to the ground wire (green)
of the power supply cord.
If four-wire receptacle of NEMA Type 14-30R is
used (see Fig. 8), a matching power supply cord
(pigtail) must be used. This cord contains four
#lO copper conductors with space or ring terminals
on dryer end terminating in a NEMA ?ype 14-30P
plug on supply end. The fourth (grounding) con-
ductor Tust be identified by a green cover and the
neutral conductor by a white cover. Cord should
be Type SRD or SRDT, with strain relief and be at
least 4 feet long. The power supply cord and strain
relief are not provided with the dryer.
Typical 30 ampere
codes permit use

ELECTRICAL CONNECTION:
It is the personal responsibility of the customer to
contact a qualified installer to assure that the
electrical installation is adequate and is in con-
formance with the National Electrical Code and
local codes and ordinances.
Electrical ground is required on this appliance.
This appliance is manufactured with the neutral
terminal connected to the frame.
