Electrical Requirements - U.s.a. Only - Whirlpool WHD3090GW Use & Care Manual

Electrical Requirements –
U.S.A. Only
It is your responsibility:
To contact a qualified electrical installer.
n
To be sure that the electrical connection is adequate and
n
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,
n
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. Connect to an individual branch
circuit. Do not have a fuse in the neutral or grounding circuit.
Do not use an extension cord.
n
If codes permit and a separate ground wire is used, it is
n
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
n
electrical supply connection. A neutral ground conductor
(white wire) is provided between the power supply neutral
connection (center terminal) and the dryer external
grounding point (green screw). If the dryer is installed with a
4-wire electrical supply connection, one end of the neutral
ground conductor must be removed from the external
ground connector (green screw), and secured under the
neutral terminal (center screw) of the terminal block. When
both ends of the neutral ground conductor are secured
under the neutral terminal (center or white wire) of the
terminal block, the dryer cabinet is isolated from the neutral
conductor. The green ground wire of the 4-wire power cord
must be secured to the dryer cabinet with the green ground
screw.
If local codes do not permit the connection of a neutral
n
ground wire to the neutral wire, see "Optional External
Ground 3-wire connection".
A 4-wire power supply connection must be used when the
n
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:
A UL-listed 30-amp power supply cord, rated 120/240-volt
n
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.
If your outlet looks like this:
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
4-wire (ground conductor) may be either green
or bare. The neutral conductor must be
receptacle
identified by a white cover.
(14-30R)
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.
3-wire
receptacle
(10-30R)
If connecting by direct wire:
Power supply cable must match power supply (4-wire or 3-wire)
and be:
Flexible armored cable or nonmetallic sheathed copper
n
cable (with ground wire), covered with flexible metallic
conduit. All current-carrying wires must be insulated.
10-gauge solid copper wire (do not use aluminum) at least
n
5 ft. (1.52 m) long.
