![]() ![]() ![]() Grounding contacts of receptacles furnished as part of the equipment are bonded to the equipment.The grounded, 4-prong plugs can also keep your home up to code. ![]() Since then, homes built after 1996 are required to have a 4-prong dryer plug with a 240-volt, 30-amp circuit to reduce the risk of shock. In the early 1990s, electric dryers used a 3-prong cord for a 240-volt circuit. The grounded conductor is insulated, or the grounded conductor is uninsulated and part of a Type SE service-entrance cable and the branch circuit originates at the service equipment. There’s a reason why there are different clothes dryer plug types.Never stand on outdoor ground soil, or touch or lean into metal. This requires a different outlet receptacle and a special heavy-duty appliance cord with a three-prong or four-prong plug to fit into a corresponding three-slot or four-slot outlet. The grounded conductor is not smaller than 10 AWG copper or 8 AWG aluminum. Tape tester leads to wood sticks, and stand on dry wood boards. Electric: An electric dryer heats the air with electric heating elements and runs on a 240-volt current.The supply circuit is 120/240-volt, single-phase, 3-wire or 208Y/120-volt derived from a 3-phase, 4-wire, wye- connected system. Electrical Wiring Configuration for a 240 Volt Electric Dryer Outlet The Black Wire attaches to Outlet Terminal X The Red Wire attaches to Outlet Terminal Y.However, the NEC specifically makes an exception for ovens and dryers:Ģ50.140 Frames of Ranges and Clothes Dryers.Įxception: For existing branch-circuit installations only where an equipment grounding conductor is not present in the outlet or junction box, the frames of electric ranges, wall-mounted ovens, counter-mounted cooking units, clothes dryers, and outlet or junction boxes that are part of the circuit for these appliances shall be permitted to be connected to the grounded circuit conductor if all the fol- lowing conditions are met. The circuit supplying this track can be connected to a - amp, single pole breaker in a 120/240-volt, 1 phase, 3 wire panel. Normally grounding a device via the neutral wire is not allowed. Study with Quizlet and memorize flashcards containing terms like One, two, or three circuit track lighting is available., Each 10 section of lighting track is rated for 15 amps at 125 volts. If you can’t quite fit a full-size washer or dryer in your home, a 24-inch washer and ventless dryer pair will usually work instead. Dryers with three-prongs are grounded using the neutral wire, when hooked up correctly (see answer for info on how to do that). ![]()
