STACKED WASHER/ELECTRIC DRYER INSTALLATION
Dryer 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, 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.
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.
If local codes do not permit the connection of a neutral ground
■
wire to the neutral wire, see the "Optional 3-wire 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, (2) mobile homes, (3) recreational vehicles,
and (4) areas where local codes prohibit grounding through the
neutral conductor.
REQUIREMENTS
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:
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.
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 copper wires and match a 4-wire
receptacle of NEMA Type 14-30R. The ground wire
(ground conductor) may be either green or bare.
4-wire
The neutral conductor must be identified by a white
receptacle
cover.
(14-30R)
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.
