    Outlets for Washer/Dryer Combo

    Hello,

    If there is a stacked Washer/Dryer combo in a dedicated closet do i need to have one receptacle for washer and one for the dryer or one 30A-2P will take care of both the washer and the dryer?

    210.11C(2) says that i need to have at least one additional 20 amp branch circuit to supply the laundry receptacle outlets..I dont know what does that laundry receptacle outlets stand for?Is it for regular 20A duplex outlet or for the washer?

    If thats the case do i need to install a 20A laundry circuit in addition to Washer/Dryer outlet?

    Thanks,
    shortcircuit...

    Are you saying that the equipment itself has only one plug, and it is designed to connect with a 30 amp outlet? If so, you will need to install a 20 amp circuit with a 20 amp receptacle somewhere in the vicinity of the closet. It can be inside the closet or on a nearby wall. Think of it as being used for an iron, which is a laundry-related appliance. Obviously, they won't be able to do their ironing inside the closet. But they may be able to put up the ironing board near the closet. Nothing in the code tells us what the owner is required to plug into the laundry outlet.

    On the other hand, does the equipment have two plugs, one configured for a 30 amp outlet and the other configured for a standard 20 amp outlet? If so, you will need a separate 20 amp circuit anyway.

    Yes you need both receptacles. We just did a 720 unit building with the stackable washer and dryer requiring a single 30 amp receptacle. So we installed another 20 amp receptacle right next to it. BTW they're both behind the unit.

    Probably a good idea to install both anyway aside code, you never know when the stack unit may become a seperate stackable washer/dryer that would require each type of receptacle.

    So irrespective of whether one simplex outlet for washer and one 30A for dryer i still need to install 20A receptacle in the area?

    That was my question too..If its a stackable unit does one 30A receptacle suffice for both washer and dryer? I have a LG WM3488HW combo unit..I tried looking at manufacturer spec sheet for power connection and it was saying one 3 prong receptacle is required but no where it was saying the size of the receptacle..
