You probably have a hot wire, a load wire and a bare ground. Also sounds like you have no neutral. You must determine which is the hot wire (has voltage) and connect it to the hot – wire (Red or black) on the switch (Should be in the wiring diagram of the switch).
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, What happens if there is no 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.
Also to know is, Why does my light switch not have a neutral wire? What is a Neutral Wire and Do I Have One? 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.
Subsequently, question 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.
Also, How do you install a neutral wire?
How do you wire a switch without neutral?
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.
Do you have to hook up a neutral wire?
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.
Is a neutral wire required?
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. Also known as a return wire.
Does my wiring have a neutral wire?
The only way to be absolutely sure that you have found a neutral wire is to check the voltage (110V/120V) between the white wire and the “hot” (usually black in color) wire in the box. In a standard switch/dimmer, the “hot” is using one of the two wires connected to the switch.
Do you need a neutral at a switch?
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)]. The purpose for this is to complete a circuit path for electronic lighting control devices, such as occupancy sensors.
Why is there no current in a neutral wire?
The current through the neutral wire is hardly ever zero, because the vast majority of circuits are single phase, and the neutral carries the same current as the hot wire. … As there is no potential difference between the two ends of neutral in other words voltage at both ends is same, hence no current flow is observed.
Do new homes have neutral wire?
US houses built from the 1980s on Usually have a neutral at the switchbox. Beginning in 2011, the national electrical code required a neutral at almost all switch boxes.
How do you get a neutral wire out of a light switch?
– The neutral wire provides power to the light switch, even when the lights are off. …
– The neutral wire may or may not have been connected to your previous switch.
– Neutral wires are typically white and may be found bundled inside the back of the switch box.
Do pilot light switches require a neutral?
Note: Pilot light switches require a neutral wire; Illuminated switches do not require a neutral wire.
Does a neutral wire carry current?
To sum up, a live wire carries the full load current, while a neutral wire carries some current, only when the loads are not balanced. … But neutral is also connected to the live wire through the device being powered, so the voltage close to the device won’t be zero if the device is on.
Can you add a neutral wire to a light switch?
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.
Do most houses have neutral wire?
All houses have a neutral wire, so the better question is, “Do I have neutrals in my switch boxes?” … If you have an outlet on the wall near the switch, the switch box almost certainly contains a neutral. If they are gang switches, then there’s a much higher likelihood of having neutral wires.
