PROBLEM TO BE SOLVED: To provide a wire harness capable of preventing a cable or load from being damaged due to a short circuit.SOLUTION: In a wire harness 13 that has a first power supply line 4, over which a high supply voltage is supplied, and a second power supply line 11, over which a low supply voltage is supplied, tied together, the first power supply line 4 and second power supply line 11 are separated from each other with a line short circuit prevention member 6 that is grounded via a grounding line 7. The current capacity of the line short circuit prevention member 6 and grounding line 7 is made larger than the rated current of the first power supply line 4 and a first fuse 3 interposed between the first power supply line 4 and a battery 1.SELECTED DRAWING: Figure 1
【課題】短絡による電線や負荷の損傷を防止し得るワイヤーハーネスを提供する。【解決手段】高電源電圧を供給する第一の電源供給線4と、低電源電圧を供給する第二の電源供給線11とを纏めて配索するワイヤーハーネス13において、第一の電源供給線4と第二の電源供給線11を、接地線7を介して接地した電線短絡防止部材6で隔離し、電線短絡防止部材6及び接地線7の電流容量を第一の電源供給線4及び該第一の電源供給線4とバッテリー1との間に介在される第一のヒューズ3の定格電流より大きくした。【選択図】図1
