I purchased a motion sensor to operate the lights in my garage. The Motion sensor has four terminals labeled LNLN. When I remove the switch, I have a Black wire, white wire, bare wire, and a RED wire which is puzzling me.
The instructions are below.
The red wire is confusing me. Thanks for your Help

Normally Black is the hot supply or L, the white is the neutral N both from the supply and to the load the red wire is the switched hot. This is how all the motion sensors work that I have installed. But you don’t show which wire is red but this is the most common. Most electricians use Red as a switched hot but it is not a requirement to do so.
