ELECTRICAL REQUIREMENTS FOR ELECTRIC DRYER UNITS

A. A three-wire (Fig. 2) or four-wire (Fig. 3),

single phase, 120/240 volt, 60 Hz, AC only

electrical supply is required on a separate

30-ampere circuit, fused on both sides of

the line. A time-delay fuse or circuit

breaker is recommended.

B. Most local codes permit the use of flex

ible, 30-amp rated, power supply cord (pig

tail). The power cord must be plugged into

a mating 30-amp receptacle (NEMA type

10-30R). A U.L- listed strain relief must

be installed where the power cord enters

the dryer.

C. THE DRYER MUST BE CONNECTED

WITH 10-GAUGE MINIMUM COPPER

WIRE ONLY. Do Not use aluminum wire

which could cause a fire.

D. The power supply cord (pigtail) can be

removed and the appliance can be con

nected directly to an individual 30-ampere

fuse circuit breaker box through flexible

armored or nonmetallic sheathed, 10-

gauge minimum copper cable. It is the

personal responsibility and obligation of

the customer to contact a qualified elec

trician to assure that the electrical instal

lation is adequate and is in conformance

with National Electrical Code ANSI/NFPA

70-1987 (or the latest edition) and local

codes and ordinances.

Important: Allow slack in the line between the wall and the appliance so that it can be

moved if servicing is ever necessary.

A U.L.-iisted strain relief must be provided at each end of the power supply cable (at the appliance and

at the junction box). Wire sizes (10-gauge COPPER WIRE ONLY) and connections must conform with

the 30-ampere circuit rating.

E. For mobile home installation, the three-wire power supply cord must be removed and the

appliance wiring must be revised. The appliance frame must not be connected to the neutral

terminal, but must be connected to the grounding wire (green) of the power supply cord.

See Alternate electrical connection - mobile home installation, for detailed instructions.

If a four-wire receptacle of NEMA type 14-30R is available, a matching power supply cord (pigtail)

must be used. This cord contains No. 10-gauge copper conductors with spade or ring terminals on the

dryer end and terminating in a NEMA type 14-30P plug on supply end. The fourth (grounding) must be

identified by a green cover and the neutral conductor by a white cover. Cord should be at least three

feet long. The four-wire power supply cord and strain relief are not provided with the dryer.
