These rooms require that a wall switch be placed beside the entry door of the room so that you can light the room before entering it. It can either control a ceiling light, a wall light, or an outlet connected to a desk lamp. The ceiling fixture must be controlled by a wall switch and not a pull chain type light. Wall receptacles should be placed no farther than 12 feet apart. Dining rooms usually require a separate 20-amp circuit for one outlet used for a microwave, entertainment center, or window air conditioner.
