ELECTRIC DRYER 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.
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
and (2) areas where local codes prohibit grounding through
the neutral conductor.
