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.
Electric Dryer Power Supply Cord
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 “U” shaped spade terminals
with upturned ends.
■
A UL listed strain relief.
If your outlet looks like this:
4-Wire
Receptacle
(14-30R)
3-Wire
Receptacle
(10-30R)
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.
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.
