How to Identify a Neutral Wire | Leviton

This video will help you identify if a neutral connection is available in a light switch location. A neutral wire is required to install Leviton Decora Smart devices, including Z-Wave, Wi-Fi, HomeKit and select Decora Digital with Bluetooth solutions.

Thank you, I had a three way switch and single pole in the same box. I wanted to connect the smart switch to the single pole but none were connected to the neutral. This showed exactly what I had as the back of the box, two white wires connected by a screw cap. Once I connected the white wire from the smart switch to the other two everything worked perfectly.

They said I need a license to perform the work, I said no I don't, I got the YouTube.

Although working in the field actually does help. Diagnosing power outages ain't no walk in the park.

Not so sure one should assume that any extra white wire is necessarily a neutral without testing it!

Very informative thanks for making this

Dunno in which country you live, but in Europe the color codes for wires are explicit for each wire and this code is applied by everyone ... So there's no question about line, neutral or ground wires ...

A Electrical Engineer told me Each neutral has to be on its own circuit to the leg, if other neutrals from other circuits are tied together it will cause a E-field in your home, your power will still work but to eliminate the E field that is what is necessary to do

Why are there 2 white wires connected together on the right

[shreddder]

You can identify a neutral because it doesn't want to get involved in the circuit.

It’s the white one pigtailed in the back

I am trying to install a wifi switch which contains 2 black wires, 1 green, 1 white.
The wall switch in my room has the 2 black wires, 1 copper, and the 2 bundled white wires.
Please let me know if my thinking is correct because every video I see they are connecting the green (ground) to a red wire which I do not have.

1. 2 black wires (Load) go to the 2 black wires on the switch (Interchangeable)
2. 1 white wire (neutral) connects to 2 white wires
3. Green wire (ground) connects to the copper wire???

I was trying to help someone on youtube connect a smart switch without a diagram. He was confusing me by stating the the neutral was required to power wifi and etc. Turns out your wording is misleading, the grounded neutral provides a current return path for the electronics in your switch. The black wire is the hot wire powering your switch.

Thank you. Do you have to have the power on while doing this?

[IPvFreely]

So here’s a dumb question. I have the two whites twisted and capped. So how do I connect one of these to the switch? Uncap, connect one of the whites to the switch, and re-cap the other white?

I tried to install one and I do not have power anymore in the switch and some outlets, I have 4 whites they were all together and two blacks and green ground, it is a receptacle for two switch lights and not working anymore, I found the one white wire that is allowing the wifi connection but the switch and four outlets stopped working, using the volt tester I can tell there is power, please help!
