ELECTRIC DRYER INSTALLATION REQUIREMENTS
Electrical Requirements – U.S.A. only (cont.)
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.

If using a power supply cord:
Use a UL listed power supply cord kit marked for use with

be at least 4 ft. (1.22 m) long. The wires that connect to
the dryer must end in ring terminals or "U" shaped spade
terminals with upturned ends.
A UL listed strain relief.

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
receptacle
be identified by a white cover.
