The large house wiring kit by Cir-Kit Concepts, Inc has all the basic starter kit items plus a double quantity of tapewire, eyelets and brads. These added items will easily allow the wiring of a 10- to 12-room dollhouse. A special circuit-breaker protected 20-watt transformer is included to provide power for up to 33 twelve-volt or 46 sixteen-volt GOW (grain of wheat) bulbs. An in-line power switch provides an on/off light control without the need to disconnect the lead-in wire from the dollhouse.
