Leviton Presents How To Install A Decora Digital Decora Smart 3 Way Switch
Smart switch no load wire. A switch box with no neutral loop will usually only have three wires see image below. Youll need a tester and some basic electrical knowledge to determine which is line and which is load to properly wire the new smart switch. Two of the wires will be the current carrying wires that power the light. Get the nano switch and install it at the light. As mentioned this is supposed to be indicated by code but is often overlooked. Strictly speaking no there is no way to wire a smart switch without a load because the smart switch itself is a load.
Traditional wiring usually has the source feed go to the switch and then to the load. The bridge is needed because the programming of your login and wireless network details are stored within the hub rather than on a micro controller inside the smart switch. The third wire should be the ground wire and is usually colored green or bare wire. Switch without neutral wire the reason that some smart switches wont work in this configuration is that the switch is breaking the circuit when it is off so power is not flowing through the switch. Interchanging the line and load wires on a conventional outlet has no effect on the outlet but doing so on a gfi outlet renders the breaker ineffective and creates a dangerous situation because the outlet wont give the protection its designed to give. Thats why smart switches generally require a neutral so it can realize 120v potential between line and neutral to power itself.

For smart switches that function without a neutral wire a home hub is essential. Switch loops can use a variety of colors including the really old heavy gauge brown wire for homes 50 years old or more. In the box for the light switch there is only a line hot neutral and ground wire. The wiring youve described in the switch box is not possible what you actually have in there is a line load and ground. I tried using a ge 12727 switch connecting the hot wire to the line terminal the neutral to the neutral terminal and the ground to the ground terminal.
