Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lead wire for test with branch box capable of obtaining electric power for test and sending a necessary control signal by using the lead wire connecting an apparatus in a case and a breaker drawn out to the outside. SOLUTION: The lead wire for test with branch box includes: the lead wire 13 electrically connecting the breaker 1 drawn out to the outside of the case 2 of a switch gear and the apparatus in the case 2 via connectors 4, 5 connected to both end parts; and a branch box 20 for test which is connected in the middle of the lead wire 13 and includes branch connection terminals 20a to 20d connecting a branch wire 17 for power supply and a branch wire 18 for control signal for connecting the middle of the lead wire 13 and a tester 6 so that electric power necessary for test is supplied to the tester 6 from the apparatus side via the lead wire 13 and a switching signal S1 for test of the breaker 1 is supplied to the breaker 1 from the tester 6 via the lead wire 13.
