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 four 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
4-wire receptacle
or bare. The neutral conductor must be identified by
(14-30R)
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 solid copper wires and match
a 3-wire receptacle of NEMA Type 10-30R.
3-wire receptacle
(10-30R)
Choose a standard power supply cord connector:
Flanged spade
connectors
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.
■
Ring connectors
