The invention provides a short circuit alternating current terminal strip testing device which comprises an outer shell. Four insulation barriers are fixed on the inner wall of the left side of an inner cavity of the outer shell at equal interval, a wire leading device is arranged above each insulation barrier, each wire leading device comprises a connecting joint and a static contact, the static contacts are connected with the connecting joints through insulation wires, the static contacts are fixed at the right ends of the insulation barriers, and the connecting joints penetrate through the outer shell. A plurality of springs are fixed on the inner wall of the right side of the inner cavity of the outer shell at equal interval, the left ends of the springs are all connected with the right surface of a metal sheet, the left surface of the metal sheet is connected with the right end of an insulation reset rod, and the left end of the insulation reset rod penetrates through the outer shell. The upper surface and the lower surface of the outer shell are respectively provided with a bolt. The short circuit alternating current terminal strip testing device is simple in structure and low in cost, can be flexibly suitable for various current secondary circuit wire connection modes and greatly improves the personal safety and the work efficiency of workers.
