Our recommended way of looking for and identifying a neutral wire is outlined below:
- Look for the electrical distribution board, breaker panel, panel board, breaker box or the main electrical panel.
- Turn the main electrical feed of the switch that you are working on OFF.
- Remove the switch face plate.
- Remove the switches from the gang box (the interior box of the switch...
What does the neutral wire do in an electrical circuit?
Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.

Does a switch need a neutral?
The neutral wire allows the completion of the circuit and the switch to have power even when it's turned to the off position when you want the lights off. Without this neutral wire in place, the circuit is broken any time the switch is now in the off position.
What is neutral wire?
In an electrical circuit, a neutral wire delivers the remaining power that was left after your smart switch or any kind of appliance draws current, back to the transformer outside your house. It is a path created to facilitate that residual current goes easily back to the energy company.
What is the extra neutral wire on a smart switch?
This extra neutral wire is connected to the Neutral bus and it will have constant current flowing through it. You don’t have it and you need to install it whether it’s you or a good electrician that actually knows what he’s doing.
How to find electrical wires?
Inside a common wall box, you easily find most of the time three cables: 1 Hot wire: Commonly coded with red color at least in the U.S. Basically is the first path that the electricity takes from the transformer outside your house until any kind of electrical device connected to the circuit. 2 Neutral wire: Once any type of your household appliances draws current from the electricity company A.K.A the transformer outside, there is a residual current that needs to go back! And this wire is guilty of it 3 Ground wire: In case something terrible happen with your switch, fridge, or any device, the Ground wire will redirect that current directly to the source, avoiding an accident. If you’re lucky enough you won’t use this cable never in your life.
Why do you need to connect a smart switch to a neutral wire?
Because the current takes the easiest path always and it will go back to the transformer. So, if you want to connect your smart switch to your neutral wire, sadly you’re going to need to install a third wire that is fed with electricity.
Why isn't my neutral wire energized?
The neutral wire that is inside your wall box is not energized because it is a dead-end for electricity. You won’t have energy flowing through it unless the switch closes the circuit and sends the remaining current back to the source.
Why is the neutral bus oscillating?
Keep in mind that the bus you are looking for is the one that is sending electricity back to the transformer! It should be oscillating because it depends on how much current is being drawn from your connected devices. It will vary, but if it’s showing you information, that’s your neutral bus.
What color wires are used for neutral?
Color cables: In a standard fairly new house, the color used for hot wires is white, which is the color used for neutral wires. At Least in the U.S. but it varies depending on the state you’re living, and that’s one of the biggest reasons are so easily confused.
Why use neutral wire?

How does an electric switch work?
In a simple electric setup, you will have energy that is led through a power source. The switch will either connect your appliance to electricity or cut electricity off. This is great for old school inventions, but not if you want to have a smart outlet. Smart outlets need to have a constant stream of power.
What is a good example of a smart switch box?
Another good example would be the Lutron Caseta Wireless. Fans of smart switch boxes will probably need to choose this one until they can find other solution, if they even need one. Choose Smart Bulbs Instead. Smart bulbs have dimming functions, can be plugged into regular lamps, and can plug into regular outlets.
What happens if you don't have experience with switch boxes?
If done improperly, it can lead to injury, fires, or just a non-function switch box. It’s a somewhat complex project that can easily lead to mistakes if you don’t have experience. You really should hire someone to do this for you, since it’s better to be safe than sorry.
Can you splice a switch box to a switch box?

What is neutral wire?
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. So when it comes to designing a smart home, ...
How to tell if you have neutral wires?
The easiest way to determine whether you have neutral wires in your switches is to know when your house was built, or the last time it underwent a major renovation. If that happened after 1990, it’s most likely you have neutral wires running throughout your home. If that happened before 1980, it’s most likely that you don’t have ...
What to do if you see white wire coming out of gang box?
If you see a white wire coming out of the gang box, you likely have a neutral wire. If your switch box doesn’t have a neutral wire, you have two options. First, you can have an electrician install one. Our electrician claimed it’s not difficult work, but they’ll need to get behind your walls.
When was the neutral wire in homes built?
Most homes built after the 1980s have a neutral wire throughout the space, case closed. But my home was built right smack in the mid-1980s, meaning the wiring situation behind the walls could’ve gone either way — a quandary the Jetsons never suffered, I’m sure. So to answer Brilliant’s question and figure out if my decision to use smart switches instead of smart lights had backfired, we broke drywall.
Can you use smart switches without a neutral wire?
The non-demolition option is to use any of the best smart light bulbs or use smart switches that work without a neutral wire. A few years ago, there weren’t many companies addressing the wiring discrepancies of older homes.
Do smart switches need neutral wires?
Several of the best smart switches still need a neutral wire to complete a given circuit and stay powered 24/7. The Brilliant smart home controller, for example, demands constant power to fulfill its role as a wall-mounted display to manage your collection of connected devices. A neutral wire also provides individual dimming functionality for the controller’s switches.
Does a Cync switch work without a neutral wire?
Cync (formerly C by GE) developed a 3-wire switch last year that works without the neutral wire, making it a good choice for anyone looking to limit the necessary electrical work for raising their home’s IQ.
What happens if you connect a switch to a neutral wire?
If the switches were connected to the neutral wire, then there is a potential danger of an electric shock. Consider this, if the live wire loses its protective sheath of insulation, and it is exposed to the bare surroundings, there's a good chance that it could come in contact with another object that is able to supply it 0 volts potential, and hence, current will flow through the circuit.
What is neutral wire?
The neutral wire is electrically connected to the grounding electrode for the buildings elecrical service. The voltage present on the neutral wire is therefore considered to be at ground voltage, the same as the water pipes, heating ducts, plaster lathe behind the walls and the exposed metal surfaces of appliances, as well as conductive parts of the elecrical system that do NOT normally carry current, such as junction boxes, conduit, etc.
Why do you disconnect a neutral wire?
Current and this neutral is connected to a neutral point of a star connected winding of the distribution transformer. And in some systems this neutral is grounded for safety. So if you connect a switch to the neutral wire at home never do this. It is because if you turn off the switch i. e., you disconnect neutral line from your electrical appliances at your home. If somewhere in an electrical equipment insulation of wires fails then a person in contact will get a serious electrical shock as whole current will flow through his body because there is no neutral connected which could drain this current to ground. Hope it helps.
Why is there little or no likelihood of getting an elecric shock when touching something connected to the neutral side of?
Because the voltages present on the neutral conductor and other grounded parts is supposed to be equal , there is SUPPOSED TO BE (theoretically) little or no likelihood of getting an elecric shock when touching something connected to the neutral side of a circuit such as the threaded shell in a light socket and something that is grounded or bonded.
Why do I get a shock when I turn off my switch?
It is because if you turn off the switch i. e., you disconnect neutral line from your electrical appliances at your home. If somewhere in an electrical equipment insulation of wires fails then a person in contact will get a serious electrical shock as whole current will flow through his body because there is.
How does a smart switch work?
They capture some energy from current flowing in the hot wire. Suppose the lamp load is incandescent, and the design of the smart switch is such that instead of being turned completely off, there will be a small minimum current allowed to flow continuously. Not enough to glow the filament. A small transformer is in line with this circuit, and the transformer secondary output is rectified for use in the smart switch.
What does "old" mean in wiring?
I'd by old you mean there isn't much left to identify wires by color, you're going to have to do a little testing.
What is a neutral switch?
It's a switch in the neutral wire, instead of the hot/live/phase wire.
What happens if you put a switch on a neutral line?
In case you put the switch on the neutral line instead of live, that case becomes "switched neutral" as shown below: In this case, you need to be extra careful while servicing the appliance. Even if the switch is turned off, the appliance will get a high voltage and there is a risk of electrical shock.
How many connections does a 120V light fixture have?
A typical lighting fixture (or other appliance in US 120V design) has 3 connections:
Is ground bonded to neutral?
Ground. The important thing is that ground and neutral are bonded in the main panel. That means that, if everything is wired correctly, you could stick a wet finger from one hand on neutral and a wet finger from the other hand on ground and have no problems whatsoever.
Can you reset a hardwired breaker?
In fact, there are additional requirements that for hardwired loads in certain circumstances, there has to be a way to lock out the breaker so that if someone is working in one location and flips the breaker in a different room that controls the circuit, nobody can accidentally reset the breaker.
What is a single pole switch?
A single-pole switch just opens and closes a circuit -- it has no sense of polarity or "line/load" requirements. As a result, the two brass screws on a standard snap switch are interchangeable with each other.
What is the back of a wire box?
What you see in the back of your box is a typical North American wiring practice in a house -- two two-wire-plus-ground NM cables entering the (plastic) box via built-in cable clamps that grip the cable sheathes, with one cable being fed from an always-hot power source and the other passing switched-hot off to the fixture, while neutral passes through the box without stopping.
Can a dumb light switch be used as a neutral?
A dumb light switch has no use for the neutral, so you simply need cap off the existing neutral pigtail with a wirenut.
Where are the neutrals pushed on a switch?
Oh. That's even simpler then; the neutrals are pushed up into the back of the box, since the switch does not use them.
What color wire is used for grounding a switch?
With non-metallic cable you have a black wire, a white wire, and a bare wire for ground. The National Electrical Code requires that the feed to the switch be the white wire re-identified as any other color but white or gray.
How many black wires do you need for a switch box?
If you had conduit running to the switch box then they would just pull two black wires for the switch loop, and a green for ground.
What color wire is legal for hot and switched hot?
So here, what you are seeing is correct wire colors in use: black and black are legal for hot and switched-hot. You may be in conduit where they are not allowed to remark white wires. ** Normally neutral is omitted entirely from a switch loop. The new smart switches do need neutral.
How many wires does a switch loop need?
A switch loop needs 2 wires: hot and switched-hot (ideally black and red). There is no neutral on a switch loop**. So it's 1999, you run out to the truck to grab your /2 red-black-ground Romex... and guess what. That doesn't exist. You don't have a choice what colors come in Romex.
What is a 3 way switch?
What you have is a 3-way switch run. 2 blacks-power in and feed for light, red is the runner to/from other 3-way. Switch boxes do not use/need a neutral in them. If the installer use NMC, then he tapped black tape on the white. See NEC 404.2.
What color wires are used for NM cable?
This cable is manufactured with ground, and two or more wires, in order of color: white, black, red, and blue. (And sometimes white with red stripe). You don't have any choice what colors come in Romex..
