Why is there no neutral in a switch box?
Turns out there was no neutral…they wired the lights neutral to the ground then wired the ground to the switches ground. Apparently that light was a after thought and they couldn’t be bothered with doing it properly. Some people are just stupid, really lazy, or both. Or possibly smoking crack. This is for a standard 3 way switch.

What happens if a light switch doesn't have a neutral wire?
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. It remains has power when the switch is in the On Mode.
Can you install a light switch without a neutral wire?
Yes, you can install a smart switch without a neutral wire. There are some smart light switches and dimmers that do not require a neutral wire. These are great for DIY installers looking for an effective smart lighting solution. For example, Lutron Caseta devices do not use a neutral wire.

Do all light switches have a neutral wire?
Houses built before that may or may not have a neutral wiring. If there is an outlet (wall receptacle) near the switch, most likely that switch has a neutral. Switches that are ganged together have a much higher likelihood of having neutrals, no matter what year.
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.
How does a smart switch work without a neutral wire?
The key to creating a smart switch that works without the neutral loop is to make R1 the perfect resistance. R1 needs to restrict the current enough so that the light bulb doesn't turn on when the switch is off. At the same time, it needs to let enough current through so that the switch can power itself.
Is a neutral wire necessary?
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.
Do smart light switches need a neutral wire?
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.
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.
Can you have a neutral at a light switch?
Count them. If there are two conductors and an earth in the switch then there is no neutral. One conductor will be permanent line and the other will be switched line. If there are three or more conductors and an earth in the switch then there is most likely a neutral.
Why don't smart switches have toggles?
In all cases smart switches don’t have a ‘toggle’ feel like a conventional switch. This is simply because the on/off state of a smart switch can be changed remotely, so the position of the switch cannot be fixed one way or the other.
What is a wireless receiver switch?
These wireless receiver type switches are quite common, and used to add switches to places where wall wiring would not be practical. This one is unique in that it supports smart home integration as well, which makes it a good option for no neutral wire installation.
Where is the capacitor on a smart switch?
Some smart switches come with a capacitor that is installed at the socket end between the active and neutral wire. This takes up the small power flow used by the switch and prevents it reaching the bulb, which solves the issue. Other switches only support ‘dimmable’ LED bulbs.
Do smart switches work with Alexa?
A lot of smart switches support Amazon’s Alexa and Google Assistant, but if you need something else the options are going to be tighter. Having compatibility with more than one system is wise if you can. Doing so gives you some options if your preferred platform changes down the road for any reason. Conclusion.
Does GE have a smart switch?
GE has had a popular range of affordable smart lights for a number of years, and now have released a range of smart switches under the same C by GE branding. Unlike the GE Enbrighten range, which require Z-Wave and a neutral wire to operate, this new range offers WiFi and no-neutral options.
Do no neutral switches need ground wire?
Potential Concerns. Firstly, while they don’t require a neutral, they DO require a ground wire. That’s an issue for many looking for no-neutral switches, as they probably don’t have that either. Second, they do need the bypass capacitor discussed above if your lighting load is under 15W.
Can Inovelli dimmer bulbs be installed without a neutral wire?
Potential Concerns. Inovelli offers a few switch options, but only the Dimmer models can be installed without a neutral wire. If you’re running LED bulbs less than 25W, you’ll need a separate bypass capacitor from Aeotec.
What is a switch with a neutral wire?
Here is a diagram of a standard switch with a neutral wire: Switch with a neutral wire. A smart switch can simply tie into the white neutral wires to complete the circuit and get a source of power to keep the radios in the switch working at all times.
Why won't my smart switch work?
The reason that some smart switches won’t work in this configuration is that the switch is breaking the circuit when it is off so power is not flowing through the switch . Smart switches require a source of power because they are always communicating with a hub. If the power is cut (because the switch is off) the smart switch will not be able ...
Can you use a neutral wire in a switch box?
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. Either way, running a new wire inside the walls and ceilings ...
Do smart switches need a neutral wire?
One common problem for new smart home users is that they want to install some smart switches to control lighting, but their existing light switches don’t include a neutral wire. There are a few options for installing smart switches without a neutral wire, but first let’s check to see if you have a neutral wire.
Can a dimmable smart switch work with an incandescent light bulb?
However, it is very important that you confirm that your dimmable smart switch will work with the type of light bulbs you plan to use – many will only work with outdated incandescent bulbs.
Does a smart switch break a circuit?
The switch still breaks the circuit, but in this case the smart switch can tap into the neutral wire to keep power flowing through the switch – the electronics in the switch still break the circuit to the light, but the switch maintains a circuit so it is always receiving power.
Can you dim a smart switch without a neutral wire?
There are dimmable smart switches on the market that can be installed without a neutral wire. The key is the dimming feature, which turns the flow of power between the light and the switch down to a slight trickle. The flow of power is not enough to activate the light bulb, but it provides enough power to keep the switch communicating with your smart hub.
How to tell if a light switch is neutral?
The easiest way to determine if you have a neutral wire in your light switch box is to look, but here are a few clues if you don’t feel like doing that just yet: 1 If your house was built in the mid 1980s or later there is a very good chance you have neutral wires everywhere in your house. 2 If there is an outlet near the light switch in question it’s likely that switch has a neutral wire. 3 Light switches ganged together (like two or three right next to each other) are likely to have a neutral, regardless of the year your house was built.
Why do smart switches need neutral wires?
In the case of smart light switches, they typically require a neutral wire because they need to be powered all the time. The neutral wire allows the circuit to be completed and the switch to be powered on. This is true even when you have a smart light switch in the “off” position.
How many amps does a neutral wire carry?
If, however, only one of the hot wires is carrying a current of 15 amps, the neutral wire will carry an equal 15 amps back to the power supply, ...
What is ground wire?
Ground wires provide alternate pathways for electricity to flow in the event of a breakdown in the circuit of hot and neutral wires that normally carry the current. That alternate pathway diverts the electricity deep within the earth outside your home.
What are the wires on a light switch?
If you don’t have a coil behind the light switch, you probably only have three wires – a black, white and copper wire. In this case, you don’t have a neutral wire (even though one of the wires is white!).
How many volts does a split phase hot wire carry?
In North America homes use “split phase 240 volt current”. Which just means that each of the hot wires carry 120 volts, for a total of 240 volts. When the loads on the two hot wires are imbalanced (as they usually are), the neutral wire carries the difference back to the power supply.
Why is a neutral wire needed?
A neutral wire helps to complete this loop by bringing current (electricity) back to the power supply, completing the circuit and keeping the power on.
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.
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.
Can a neutral wire cause headaches?
So when it comes to designing a smart home, a neutral wire can cause headaches if you don’t have one at your switch location. Or if you don’t know whether you have one, like me. RECOMMENDED VIDEOS FOR YOU... Created with Sketch. Most homes built after the 1980s have a neutral wire throughout the space, case closed.
