ELECTRICAL REQUIREMENTS -
U.S.A. ONLY (SPÉCIFICATIONS

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. 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. 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 4 10-gauge solid
copper wires and match a 4-wire receptacle of
NEMA Type 14-30 R. The ground wire (ground
4-wire
conductor) may be either green or bare. The
receptacle
neutral conductor must be identified by a
(14-30R)
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 3 10-gauge solid
copper wires and match a 3-wire receptacle of
NEMA Type 10-30R.
3-wire
receptacle
(10-30R)
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.
