If you look at this diagram from the devices documentation (pdf), you'll see that there are three ways this requirement is achieved. I am trying to replace a light switch with a neutral required motion sensor light. Which is why they have a minimum load and are often not capable of switching led lights.

All The Whites Must Still Be Connected To Each Other When You Are Done!


There is no need to turn on a motion sensor light as it automatically turns on when someone crosses its beam, and it also turns off when no one crosses its beam for a certain period of time. The switch cannot work without one neutral and one hot. The good thing is that any neutral will work since every neutral is joined at a terminal box.

Sure, You Can Install Some Brands Of Smart Switches In A Junction Box That Doesn’t Have A Neutral Wire, But Until Now, You’d Also Need A Hub To Make The Smart Switch Work.


The difference this time is that there are only three wires to connect. It cannot function without at least 1 hot and one neutral. It cannot function without at least 1 hot and one neutral.

Does A Motion Sensor Switch Need A Neutral?


The neutral powers occupancy sensors and dimmers independently. The sensing circuit draws an extremely small amount of power so is using the equipment ground as a neutral path. Thus, the starter solenoid receives power from the battery only in the ‘park’ and ‘neutral’ transmission,.

The Hotwire, The Neutral Wire, And The Ground Wire.


A motion sensor light switch needs a neutral for powering the sensor and timer. For most bulb types, including incandescent bulbs, cfl, and halogens, this small current is not enough to power them on so it flows through unnoticed. This is a problem when the load lights up at the slightest current, such as led lights.

The Way Smart Switches Get Around The Need For A Neutral Wire Is To Draw A Small Amount Of Power (Enough For Their Minimal Electronics) Through The Light Socket, Basically Using The Socket’s Neutral Wire Instead.


Since all neutrals should be joined in the breaker box to one terminal block, any neutral in the house will work. The ones that include a motion sensor for example, do need a neutral. A neutral wire is a type of wire in which carries currents back to the source of power and or regular voltage.
