The invention relates to a dual-power load end wiring device. The dual-power load end wiring device comprises a wiring terminal and a plurality of dual-power load side switch connecting lines, wherein the wiring terminal comprises a terminal base, a plurality of bolts, a plurality of conductors, a terminal upper cover and a plurality of screws; a plurality of grooves are hollowly formed in juxtaposition at the upper part of the terminal base; an opening is formed at the lower part of each bolt; two ends of each groove are respectively provided with one bolt, and the openings on the two bolts in the same groove are respectively inserted outside two ends of one conductor; two rows of round holes are formed at two sides of the terminal upper cover, and screw holes are formed in the middle of the terminal upper cover; the screws are installed in the screw holes; and one end of each dual-power load side switch connecting line is connected with a switch lead-out end on a dual-power, and the other end is connected with one end of the conductor. In the dual-power load end wiring device, the two switches on the dual-power are connected to the wiring terminal through the plurality of dual-power load side switch connecting lines, and a user only needs to directly connect a plurality of load power lines to the wiring terminal when in use, therefore, the invention has the advantages of very convenient operation and convenient wiring and maintenance.
