Summary of the Article
1. What happens if you don’t have a neutral wire for a smart switch? If you don’t have a neutral wire at the switch, you can install the relay in the light fixture box where there is a neutral. This allows you to control the switch without a neutral wire.
2. Can you install a smart light switch without neutral? Yes, smart light switches can be installed without a neutral wire. They work by using the neutral wire at the load (light fixture) instead of at the switch.
3. What happens if there is no neutral wire? Without a neutral wire, there would be no circuit for electricity to flow along and complete its circle back to the power source. Neutral wires are essential for the proper functioning of the electrical system.
4. What smart switches do not require a neutral? Some smart switches do not require a neutral wire. Examples include the Lutron Caseta Dimmer, Aqara Smart Wall Switch, and Moes No Neutral Switch. These switches offer easy installation and good integration with smart systems.
5. Can I use ground as neutral? No, ground wires cannot be used as neutral wires because they do not provide the normal return path for the current.
6. Are neutral wires required by code? Neutral wires are required by most modern US electrical codes. They are mainly found in newer homes built after 1985. Make sure to turn off the voltage to a switch or outlet before working on it to avoid electric shocks.
7. How do you make a neutral wire for a smart switch? To create a neutral wire for a smart switch, you can find the neutral wire on the other side of the load wire (usually in the light fixture) and run a wire back down to the switch.
8. What happens if a switch doesn’t have a neutral? Switches do not have a neutral wire because they are meant to control the supply-side of electrical devices. Having a neutral wire at the switch could lead to safety hazards.
What happens if you don t have a neutral wire for a smart switch
Here's how it works:
If you don't have a neutral at the switch, then you will have a neutral at the load (light fixture). Therefore, you install the relay in the light fixture box where there is a neutral.

Can you install a smart light switch without neutral
Just like this and you can see that light level going up and the bar on the side turning on we're going to turn this off right now but what's great about a smart light switch no neutral required is
What happens if there is no neutral wire
Without it, there would be no circuit for electricity to flow along and complete its circle back to the power source. Neutral wires are important at every point in your entire electrical system—from when they leave a transformer or fuse box all the way through their journey until they return to the source.

Can I use ground as neutral
We cannot use ground as neutral as it doesn't provide the normal return path for the current.
Are neutral wires required by code
Neutral wires are mainly found in newer homes (built after 1985) and are required by most modern US electrical codes. Don't get shocked! To avoid an electric shock, always turn off the voltage to a switch or outlet at the circuit breaker before removing the cover.
How do you make a neutral wire for a smart switch
Find that neutral wire which will be on the other side of wherever the load wire is and you could run that wire back down into the light switch and now you have a neutral wire. For your smart light
What happens if a switch doesn’t have a neutral
Switches don't have a neutral wire, because, ONLY the supply-side of electrical devices are meant to be switched, to disallow leaving 'HOT' , ungrounded, devices becoming shock-hazards. The presence of a neutral wire would most likely be the return from the lighting-receptacle, being controlled by the switch.
Do all WIFI switches require a neutral
The short answer is – Yes, you should! Common smart switches require a neutral wire. So before you are going to buy a big amount of smart light switches, make sure if your walls have the neutral wire installed. This is especially important if you are renovating an older house or apartment.
Is a ground wire the same as a neutral wire
The key distinction is that ground wires are only carrying current in case something goes wrong. They're a failsafe, essentially, directing current away from the plugged-in or lighting device if a problem occurs, such a short. The neutral wire completes the circuit and allows electricity to flow.
Does the NEC require a neutral at every switch
Section 404.2(C) requires a neutral conductor to be installed at specific lighting switch locations. Not all light switches require or even use a neutral but some have electronic circuitry that requires a current return path to complete the circuit even when the device is in the off position.
Is it OK to use ground as neutral
We cannot use ground as neutral as it doesn't provide the normal return path for the current.
Why do smart switches use neutral
Why do I need a neutral wire Smart Home requires a neutral to power it. If you were to directly swap a traditional switch that uses light-first wiring, and therefore has no neutral at the switch, then the power for the lights would be running through the switch which it is not capable of supporting.
What is the difference between the hot wire and the neutral wire
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.
Can I use earth instead of neutral
Yes; if required, you can connect an earth wire instead of a neutral wire for completing the current path. This is because current requires a path to complete; and as the neutral was doing the same thing with zero potential, an earthing wire can also do the same thing by completing the path with zero potential in it.
Does NEC require a neutral in every box
Neutrals. When wiring lighting circuits supplied by a grounded general-purpose branch circuit, the 2011 NEC now requires you to provide a neutral conductor at nearly every switch point [404.2(C)].
Is grounding the same as neutral
The key distinction is that ground wires are only carrying current in case something goes wrong. They're a failsafe, essentially, directing current away from the plugged-in or lighting device if a problem occurs, such a short. The neutral wire completes the circuit and allows electricity to flow.
Do you need a neutral wire if you have a ground wire
The ground wire is generally green and the neutral wire is white. If you connect the ground wire to the neutral, the ground wire will become hot. As a result, there will be a high possibility of electrical shock. To operate an electrical appliance, you will need both hot and neutral wires.
Is a neutral required at every switch
Not all light switches require or even use a neutral but some have electronic circuitry that requires a current return path to complete the circuit even when the device is in the off position.
Can I tie the neutral and ground together
Neutral is the return path of the current, and ground wire holds the fault current to trip the breaker in protecting the person and the facility. The neutral and ground should never be bonded together in the facility except for the main panel.
What happens if you connect neutral to ground
If you connect the ground wire to the neutral, the ground wire will become hot. As a result, there will be a high possibility of electrical shock. To operate an electrical appliance, you will need both hot and neutral wires.
Is it OK to connect neutral to ground
Neutral is the return path of the current, and ground wire holds the fault current to trip the breaker in protecting the person and the facility. The neutral and ground should never be bonded together in the facility except for the main panel.
Is neutral and earth the same
Neutral wire always carry a return current in the normal conditions in the AC circuit. Earth wire does not carry any electric current under normal condition, it carries current only when there is a fault in the device. The standard color for neutral wire is black. The color of earth wire is green or green-yellow.
What size neutral wire is required by NEC code
A. Section 200.6 of the 2020 NEC outlines the identification requirements for grounded conductors. Neutral conductors 6 AWG and smaller must be identified by any of the following means (Figure): (1) Insulated conductors with a continuous white outer finish.
Why neutral wire is not used in a switch
If the switch is placed in the neutral wire, the electrical appliance is still connected to the high voltage live wire even when the switch is opened. This may cause the user to get an electric shock if he touches the live wire accidentally.
