The utility model discloses a wiring circuit for a UPS bypass stand-by power supply. The wiring circuit comprises a 1#UPS, 2#UPS and a main power supply circuit and a by-pass power supply circuit supplying power respectively to the 1#UPS and the 2#UPS. The 1#UPS output and the 2#UPS output are parallelly connected to form a UPS parallel output, which supplies power to a load, respectively through a 1#UPS output switching-on indicating lamp, a 2#UPS output switching-on indicating lamp, a 1#UPS output switching-on breaker and a 2#UPS output switching-on breaker. A UPS hand-operated by-pass input line is connected with a 2#UPS bypass power supply, and a hand-operated bypass output line is connected with the UPS parallel output. A hand-operated by-pass switching-on breaker is arranged between the UPS hand-operated by-pass input line and the hand-operated by-pass output line. The UPS power supply output line is connected with a commercial power supply line, thereby effectively connecting two power supply means, an
