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 Electric Code requires a 4-wire 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 conductor 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
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.
GROUNDING INSTRUCTIONS
SAVE THESE INSTRUCTIONS
■
For a grounded, cord-connected dryer:
This dryer must be grounded. In the event of malfunction or
breakdown, grounding will reduce the risk of electric shock
by providing a path of least resistance for electric current.
This dryer uses a cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged
into an appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
■
For a permanently connected dryer:
This dryer must be connected to a grounded metal,
permanent wiring system, or an equipment-grounding
conductor must be run with the circuit conductors and
connected to the equipment-grounding terminal or lead on
the dryer.
WARNING:
Improper connection of the equipment-
grounding conductor can result in a risk of electric shock.
Check with a qualified electrician or service representative
or personnel if you are in doubt as to whether the dryer is
properly grounded. Do not modify the plug on the power
supply cord: if it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
