A wireless socket bar generally has two or three jacks, one of which is a ground jack and needs to be connected to the ground cable of the power cable. The other two jacks are neutral and live wires, respectively.
Remove the insulation layer of the power cable before connecting the cable, and then insert the exposed wire into the corresponding jack at the same depth, and tighten the cable with screws after insertion. Finally, plug the socket strip into the power outlet. Pay attention to safety when using, do not overload use.
