How do you wire a smart light switch with a neutral?
Quote from the video:
Quote from Youtube video: Down here and we do have a neutral water we've got a white wire here. And this neutral wire that means that we can use any of these three light switches any of these three smart light switches.
Do I need neutral wire for Smart switch?
Every smart switch needs a neutral wire attached because they need to stay powered all the time. Without a neutral wire, there is a single circuit between the bulb, power source (or junction box), and light switch.
Can you use a ground wire for the neutral wire in a smart switch?
While connecting the neutral of a smart switch to ground might work, never do this! The reason it will work is that ground is often connected to neutral in the electrical panel, meaning it will be at a very similar voltage allowing current to flow from hot to ground.
How do I install a smart switch without neutral?
If you want to use smart switches and don’t have a neutral wire in your switch box, you can hire an electrician to run a neutral wire between the light fixture and the switch. You can also have an electrician rewire the switch and light fixture, which is potentially more expensive.
Can I add a neutral wire to my light switch?
Quote from the video:
Quote from Youtube video: Because typically it means you're gonna have to open up walls or that you're gonna have to run new wiring through conduit.
Can I use ground as neutral?
A ground is not a neutral period. The last thing you want is the chassis of your washer as a current carrying conductor. If your house has a bonded neutral and ground then it should be at only at one connector and that is your circuit breaker panel and nowhere else.
Do new homes have neutral wire?
US houses built in the 1980s usually have a neutral switchbox. The national electrical code requires a neutral at most switch boxes.
Why do switches not need a neutral?
If that was a neutral wire of a smart switch that you connected the red wire to it should not be connected through a load. It may still work but it is not right. @Ryan stop saying “neutral on the switch”, there is no such thing as that. Switches don’t get neutrals, they only want 2 wires: hot and switched-hot.
Is neutral wire necessary?
In terms of a home’s power flow, the neutral wire provides a return path for currents essential to most modern U.S. electrical codes. Combined with a power source and ground wire, you have the makeup of a contemporary light switch, but earlier switches operate without the neutral.
Can I pull a neutral wire from anywhere?
No, you can’t steal a neutral wire from another circuit. Each neutral wire is the return for the corresponding hot. If you “steal” a neutral from another circuit you run the risk of overloading that neutral wire (overheat, fire risk).
What do you do with an unused neutral wire?
It’s supposed to be marked/taped though to designate this. Alternatively, it could simply be an unused neutral leg that was brought in with the hot leg and should just be capped if not used. Newer building codes require you to run a neutral leg to switch boxes so that things can be “run” from the box.
What if my house doesn’t have a neutral wire?
Call in an electrician and get him to run a neutral wire running from the light fixture to the switch. You could also ask the electrician to rewire both the switch and light fixture, but this is more complex and therefore costlier.
What will happen if switch is connected to neutral wire?
If the switches are connected to neutral wire, no current will flow through the appliance and hence it will not operate.
Why is there a neutral wire on my light switch?
Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
Should a switch be on the live or neutral?
The switch must be placed in live wire to maintain the body of appliance at zero potential in the switch off position and if the switch is kept in neutral wire, then the body of the appliance to keep the body at infinite potential in the switch on position.
Does it matter which way live and neutral?
The answer is fairly clear. Yes it matters, because it reduces the possibility of an appliance/device becoming a shock hazard.
