PROBLEM TO BE SOLVED: To make a power supply sharable by connecting power consuming equipment with a power supplying means through internal wiring, and providing a junction box containing an additional circuit which consume a part of the power supplied from the power supplying means. SOLUTION: When an additional circuit built in a junction box 1 is added to power consuming equipment 2, the junction box 1 is inserted is inserted in a manner when junction box is sandwiched between the power consuming equipment 2 and a battery 3. In this state, the power consuming equipment 2 and the battery 3 are connected with each other through wiring in the junction box 1 to supply power to the power consuming equipment 2. In the junction box, a part of the power supplied from the battery 3 is utilized to operate the additional circuit. Thus, a power supply can be shared between the power consuming equipment 2 and the additional circuit in the junction box 1. |
