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.
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:
If your outlet looks like this:
Choose a standard power supply cord connector:
Flanged spade
connectors
Ring 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.
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.
