What happens if switch is connected to neutral?
If the switches are connected to neutral wire, no current will flow through the appliance and hence it will not operate.
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.

Why would you switch a neutral wire?
Why do some switches require a neutral wire? Switches that require a Neutral are providing some additional functionality that requires 120VAC power to operate. Background: In a typical AC power circuit, like a ceiling light, electricity circulates between a Hot wire and a Neutral wire.
Is it OK not to connect neutral wire?
It normally goes into the Neutral wire. If that is disconnected, the current should have no where to go so your device will stop working. If your device is improperly designed, the current from the Hot will flow into the Ground wire. The device will then work, but it would be unsafe to use.
Why use neutral wire?
A neutral wire makes smart home creation easier and also better completes your electrical circuits.

Is it bad to turn off a live MCB?
It's a switch in the neutral wire, instead of the hot/live/phase wire. It is generally considered to be a bad thing, as turning the switch off turns off the appliance, but there is still a live feed to the appliance.
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.
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.
What is a Light Switch?
The light switch is an electrical component used to control and operate the lights, bulbs, the equipment connected with it, and any electrical outlet connected with it. Switches are of different types and are used for different purposes. Usually, the switches only do ON or OFF the device that is connected with it.
How a Light Switch Works?
When the current is passed through the switch to the load, that is, bulbs, ceiling lights, etc. It makes the light turn ON. But when you push the button to OFF the light, it entirely breaks the circuit, and the passing of electricity is interrupted. What happens is there is always a space between the hot wire and the switch.

Why do light switch boxes need neutral wires?
The reason is a direct result of the increasing popularity of "control devices" which are also known as smart switches.
Why is neutral wire important?
The neutral wire is as important as the hot wire, they function together as a pair to power things, and both are needed for the light to turn on. All electrical circuits have a return path. This is just a very simple one.
What is neutral wire?
The neutral wire is the electricity's return path after it has entered a load, which is a fancy way of saying any device that uses power. An electrical circuit will always have two wires going to and from equipment needing to be powered.
What happens when a switch is turned off?
Once turned off, there will be no current flow in the circuit, and nothing will be powered on. Same circuit as earlier. Notice the switch only. has access to the hot wire.
Why do we need a ground wire?
The ground wire exists to provide a way for the electricity to get back to "ground" safely. In the absence of a ground wire, an unknowing human who touches a faulted circuit could bridge the hot to ground through their body, leading to severe injury and even death.

Do smart switches work with ground?
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.

Is a neutral the same as a ground?
The Neutral is basically the same as a ground. If you were to fully investigate a household electrical system, you'd find the ground is connected to the neutral bar in the main panel. They're essentially the same thing. For safety reasons, you want to eliminate the source of the power at the device, not the ground.
Do you switch the hot or the neutral?
As far as I know, you always switch the hot. Just think about what it is you are "switching".... you are turning off the flow of electricity, when switching the neutral you are interupting the flow...there is a difference.
