The color of the Line wire is usually black and the Load wire is usually red, black, or blue (less common). If you notice that both are the same color for you, please use the guideline below to determine which wire is which. Once you identify the wires, use the labels provided in the Orro Switch packaging to mark them and attach the wires to the correct port on the back of the Switch.
NOTE: If you are unsure, please contact a professional electrician.
Load Wire - Generally connected to the top half of your switch. If the wire is coming from the top of the switch box, it is likely your load wire.
Line Wire - Generally connected to the bottom half of your switch. In some cases, line wires are marked with “line”, “pwr”, or a lightning bolt symbol. Also, on some traditional switches, the line wire is connected with a black or silver screw that is a different color than any other screws on the switch.
If the Orro Switch does NOT turn on after you have finished installation, it can be due to the Line and Load wires being installed in the wrong port. To see how to swap the wires, please use the safety precautions and steps indicated here.
