Electrical test wiring device and test system

The invention provides an electrical test wiring device and a test system, and relates to the technical field of electric power detection. The electrical test wiring device comprises a device main body; the plurality of first binding posts are arranged on the device main body and are used for being electrically connected with a transformer; the plurality of second binding posts are arranged on the device main body and are used for being electrically connected with test equipment; and the plurality of function buttons are arranged on the device main body, the first binding post and the second binding post are electrically connected through a plurality of function circuits, and the function buttons are used for controlling the on-off of the corresponding function circuits. According to the technical scheme, on-off between the transformer and the test equipment can be controlled without being influenced by a low-temperature environment, so that various detections on the transformer are realized, and the problems
