Electrical Requirements - U.S.A. Only
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 Electric 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 in “Electrical Connection - U.S.A. Only”
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:
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 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),
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.
