ELECTRIC DRYER POWER HOOKUP
Electrical Requirements - U.S.A. Only
It is your responsi
b
ility
■
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.
■
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 “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.
G
rounding 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 cor
d
:
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:
4-wire receptacle
(14-30R)
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 identified
by a white cover.
If your outlet looks like this:
3-wire receptacle
(10-30R)
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 connecting

irect 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), protected 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.
