Wiring clamp and circuit breaker testing device

The invention relates to the technical field of circuit breaker testing, and discloses a wiring clamp and a circuit breaker testing device. The wiring clamp comprises: a clamp body, wherein the clampbody comprises a clamp shell, a fixed clamp claw and a movable clamp claw, a chute is formed in the clamp shell, the fixed clamp claw and the movable clamp claw extend into the clamp shell from the chute, and the movable clamp claw can move along the chute; and a connector which is fixedly arranged on the side, deviating from the chute, of the tong shell, a first interface and a second interface are formed in the connector, the first interface is electrically connected to the fixed tong claw through a hard wire, and the second interface is electrically connected to the movable tong claw through a soft wire. The first interface on the joint can be used for accessing a current test line, and the second interface can be used for accessing a voltage test line. By means of the wiring clamp, a cable of the circuit break
