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.
■If local codes do not permit the connection of a neutral ground wire to the neutral wire, see “Optional 3-wire connection” section.
■This dryer is manufactured ready to install with a 3-wire electrical supply connection. The neutral ground wire 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 wire must be removed from the external ground conductor screw (green screw), and secured under the neutral terminal (center or white wire) of the terminal block. When the neutral ground wire is secured under the neutral terminal (center or white wire) of the terminal block, the dryer cabinet is isolated from the neutral conductor.
■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 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 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 outlet 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 4 10-gauge solid 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 outlet 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 solid copper wires and match a 3-wire receptacle of NEMA Type 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 cable (with ground wire), protected with flexible metallic conduit. All current-carrying wires must be insulated.
■10-gauge solid copper wire (do not use aluminum).
■At least 5 ft (1.52 m) long.
GROUNDING INSTRUCTIONS
■For a grounded, cord-connected dryer:
This dryer must be grounded. In the event of malfunction or breakdown, grounding will reduce the risk of electric shock by providing a path of least resistance for electric current.
This dryer uses a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
■For a permanently connected dryer:
This dryer must be connected to a grounded metal, permanent wiring system, or an equipment-grounding conductor must be run with the circuit conductors and connected to the equipment-grounding terminal or lead on the dryer.
WARNING: Improper connection of the equipment- grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service representative or personnel if you are in doubt as to whether the dryer is properly grounded. Do not modify the plug on the power supply cord: if it will not fit the outlet, have a proper outlet installed by a qualified electrician.
