To be sure that the electrical connection is adequate and in

with the National Electrical Code, ANSl/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,

[]
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, (2)
mobile homes, (3) recreational vehicles, and (4) 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
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 ouUet 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 ouUet 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.
