One end of the wire is equipped with a plug for connection to the CK1007 Junction Splice on the dollhouse and the other with spade lugs for connection to the transformer output terminals. This lead-in wire may be used for those installations requiring the convenience of total dollhouse on/off power control. (Eliminates need for unplugging lead-in wire from dollhouse to disconnect power.) Includes added in-line fuseholder. Can be used for protection of any transformer with screw terminals. The fuse holder is a threaded assembly and accepts all Cir-Kit fuses. Overall length, approximately 6 feet.
