PROBLEM TO BE SOLVED: To provide a low voltage mobile power source for a low voltage wiring work capable of decreasing the number of cables laid between a low voltage distribution line and a low voltage mobile power source vehicle. SOLUTION: A parallel switch 13 is provided in parallel to an opening point 17 of a low voltage distribution line LC, and a wireless synchronous phase sequence indicator 15 is provided near the parallel switch 13. The wireless synchronous phase sequence indicator 15 at least inspects phase sequence of voltages of a power source side and a load side based on the output of a power source side voltage sensor 23 and the output of a load side voltage sensor 25. The result is transmitted by air to a low voltage mobile power source vehicle 1 while the output of a current sensor 27 and the output of the power source side voltage sensor 23 are transmitted by air to the low voltage mobile power source vehicle 1.
