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.

Electrical Connection
To properly install your dryer, you must determine the type
of electrical connection you will be using and follow the
instructions in “Electric Installation.”
n
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, see “4-Wire Direct Wire
Connection.”
n 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
after 1996, (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:
n
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.
n A UL listed strain relief.
