Many electrical timers require a neutral so that the switch can be powered without sending power to the load. If you do not have a neutral at the switch box it means that the power source (line) does not come into that box and you are just switching the hot from another source.
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.
Thereof, Can I install a smart 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.
Also to know is, Can a circuit work without a neutral? Nope, that’s not how it works. Both the hot wire and the neutral wire are capable of providing charged particles—which is to say, electrons.
Subsequently, question is, Do you need to connect the neutral wire? Except in very rare situations, all neutral wires in a box must be connected. The neutral is how the current flows back to the supply, so if you don’t connect a neutral to one fitting it won’t work. You could connect three in one connector, then three in another, and have a link between the two.
Also, What happens if the neutral wire is not connected?
When the neutral wire breakage and phase-to-ground short circuit occur simultaneously, the displacement of the neutral point will be greater. After the neutral wire is broken, the shell leaks electricity, which will cause electric shock.
Do you need a neutral wire for a smart switch?
Smart switches need to stay powered up all the time, which is why the neutral wire is critical. 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.
Do switches need a neutral?
The most common requirement of any hardwired automated light switch is a neutral wire. Yes, there are a few… (read very, very, very few) switches that don’t require a neutral, but those will limit you to incandescent only. … This is a diagram of a switch with the neutral run directly to the light.
Can I add a neutral wire?
Another option to add a neutral wire is to add a new neutral wire to the switch. The neutral wires and hot wires are insulated inside the walls in proper covering. Again we recommend you hire an electrician to add a neutral wire to the smart switch from a light fixture.

What colors can a neutral wire be?
The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
Does a ceiling fan need a neutral?
You need a neutral. You can not tap a second switch for the from the existing switch box unless you change the cable to the receptacle to include a neutral and two hots.
Why does a light switch need a neutral?
Why Do Smart Switches Need Neutral Wires? Smart switches need to stay powered up all the time, which is why the neutral wire is critical. 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.
How do you add a neutral wire to a circuit?
Can a neutral wire be added?
Neutral wires can be added two ways. One way is to extend a neutral wire from a previous switch box that already contains a neutral wire. The second way is to add a new neutral wire to your house.
How do you know if a light switch has a neutral wire?
– Turn off your breaker box.
– Take off the trim plate over the switch.
– Remove the screws from your switch and pull out the existing switch to look at the wires.
– If you see a white wire (or group of them), it is VERY likely that you have a neutral in that switch box.
Do I have a neutral wire light switch?
Neutral wires are typically white and may be found bundled inside the back of the switch box. If your home was built or remodeled after 2011, the National Electric Code (NEC) requires neutral wires. If your home was built or remodeled in the mid-80’s, you’re likely to have neutral wires.
