Then choose a 4-wire power supply cord with

ring or spade terminals and UL-listed strain

relief. The 4-wire power supply cord, at least

4 ft. (1.22 m) long, must have four 10-gauge

copper wires and match a 4-wire receptacle of

NEMA Type 14-30R. The ground wire (ground

conductor) may be either green or bare. The

neutral conductor must be identied by a

white cover.

Then choose a 3-wire power supply cord with

ring or spade terminals and UL-listed strain

relief. The 3-wire power supply cord, at least

4 ft. (1.22 m) long, must have three 10-gauge

copper wires and match a 3-wire receptacle

of NEMA Type 10-30R.

4-wire receptacle

(14-30R)

3-wire receptacle

(10-30R)

If connecting by direct wire:

Power supply cable must match power supply (4-wire or 3-wire)

and be:

■ Flexible armored cable or nonmetallic sheathed copper

cable (with ground wire), covered with exible metallic

conduit. All current-carrying wires must be insulated.

■ 10-gauge solid copper wire (do not use aluminum) at least

5 ft. (1.52 m) long.

ELECTRICAL REQUIREMENTS

It is your responsibility:

■ To contact a qualied electrical installer.

■ To be sure that the electrical connection is adequate and

in conformance with the National Electrical Code, ANSI/

NFPA 70 – latest edition and all local codes and ordinances.

The National Electrical Code requires a 4-wire power supply

connection for homes built after 1996, dryer circuits involved

in remodeling after 1996, and all mobile home installations.

A copy of the above code standards can be obtained from:

National Fire Protection Association, One Batterymarch Park,

Quincy, MA 02269.

■ To supply the required 3- or 4-wire, single phase, 120/240

volt, 60 Hz, AC only electrical supply (or 3- or 4-wire, 120/208

volt electrical supply, if specied on the serial/rating plate)

on a separate 30-amp circuit, fused on both sides of the line.

Connect to an individual branch circuit. Do not have a fuse

in the neutral or grounding circuit.

■ Do not use an extension cord.

■ If codes permit and a separate ground wire is used, it is

recommended that a qualied electrician determine that

the ground path is adequate.

Electrical Connection

To properly install your dryer, you must determine the type of

electrical connection you will be using and follow the instructions

provided for it here.

■ This dryer is manufactured ready to install with a 3-wire

electrical supply connection. The neutral ground conductor

is permanently connected to the neutral conductor (white wire)

within the dryer. If the dryer is installed with a 4-wire electrical

supply connection, the neutral ground conductor must be

removed from the external ground connector (green screw),

and secured under the neutral terminal (center or white wire)

of the terminal block. When the neutral ground conductor is

secured under the neutral terminal (center or white wire) of

the terminal block, the dryer cabinet is isolated from the

neutral conductor. The green ground wire of the 4-wire power

cord must be secured to the dryer cabinet with the green

ground screw.

■ If local codes do not permit the connection of a neutral

ground wire to the neutral wire, see “Optional External Ground

for 3-Wire Connection” in the “Power Supply Cord Connection”

section.

■ A 4-wire power supply connection must be used when the

appliance is installed in a location where grounding through

the neutral conductor is prohibited. Grounding through the

neutral is prohibited for (1) new branch-circuit installations after

1996, (2) mobile homes, (3) recreational vehicles, and (4) areas

where local codes prohibit grounding through the neutral

conductors.

If using a power supply cord:

Use a UL-listed power supply cord kit marked for use with

clothes dryers. The kit should contain:

■ A UL-listed 30-amp power supply cord, rated 120/240

volt minimum. The cord should be type SRD or SRDT

and be at least 4 ft. (1.22 m) long. The wires that connect

to the dryer must end in ring terminals or spade terminals

with upturned ends.

■ A UL-listed strain relief.
