STACKED WASHER/ELECTRIC DRYER INSTALLATION
REQUIREMENTS
Dryer Electrical Requirements
It is your responsibility:
n To contact a qualied electrical installer.
n 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.
n
To 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 specied 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.
n
Do not use an extension cord.
n If codes permit and a separate ground wire is used, it is
recommended that a qualied 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
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.
Electric Dryer Power Supply Cord
If using a power supply cord:
Use a UL listed power supply cord kit marked for use with
clothes dryers. The kit should contain:
n
A 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.
n
A UL listed strain relief.
If your outlet looks like this:
4-wire
receptacle
(14-30R)
3-wire
receptacle
(10-30R)
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
identied 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.
If your outlet looks like this:
