Dryer Electrical Requirements

STACKED WASHER/ELECTRIC DRYER INSTALLATION REQUIREMENTS

It is your responsibility:

Electric Dryer Power Supply Cord

nTo contact a qualified electrical installer.

nTo 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.

nTo supply the required 3 or 4 wire, single phase, 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.

nDo not use an extension cord.

nIf 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.

n 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.

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

If using a power supply cord:

Use a UL listed power supply cord kit marked for use with clothes dryers. The kit should contain:

nA UL listed 30-amp power supply cord, rated 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 “U” shaped spade terminals with upturned ends.

nA UL listed strain relief.

If your outlet looks like this:

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

connection” section.

n 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, (2) mobile homes, (3)

recreational vehicles, and (4) areas where local codes

prohibit grounding through the neutral conductor.

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 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 three 10-gauge copper wires and match a 3-wire receptacle of NEMA Type 10-30R.
