Electrical Requirements

It is your responsibility:

To contact a qualified 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 specified on the serial/rating plate) on a

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

time-delay fuse or circuit breaker is recommended. 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 qualified 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.

If local codes do not permit the connection of a neutral

ground wire to the neutral wire, see “Optional 3-wire

connection” section.

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

electrical supply connection. The neutral ground wire 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 wire must be removed

from the external ground connector screw (green screw), and

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

the terminal block. When the neutral ground wire is secured

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

block, the dryer cabinet is isolated from the neutral conductor.

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

dryer 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, (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.

If your outlet looks like this:

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 4 10-gauge solid

copper wires and match a 4-wire receptacle of

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

conductor) may be either green or bare. The

neutral conductor must be identified by a white

cover.

If your outlet looks like this:

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 3 10-gauge solid

copper wires and match a 3-wire receptacle of

NEMA Type 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 flexible 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.

3-wire receptacle

(10-30R)

4-wire receptacle

(14-30R)
