Do LED dimmers need a neutral?
The prices of LED bulbs are dropping, making them the perfect choice to replace your energy-wasting incandescent bulbs. But if your current bulbs are on a dimmer, you may run into issues even if you install dimmable LED bulbs. If you don’t have a neutral wire, you’ll have to find a ‘no neutral required’ dimmer.
Can you install a dimmer switch yourself?
You can even install dimmers on more than one light switch if needed. You may be able to install a dimmer switch yourself if you have worked with electricity before, but if you’re uncomfortable with the process, you should hire a licensed electrician.
Do you need an electrician to install a dimmer switch?
Electricity is a mystery to many people, but some electrical projects — like wiring a switch — are so simple that anyone can do them. With a few easy steps and the right knowledge, there’s no need to hire an electrician.
How do I install a dimmer switch without a ground wire?
In that case, an exception in article 404.9(B) of the current National Electric Code (NEC) allows a dimmer without a connecting ground wire to still be installed if it is a replacement. Simply remove the dimmer wire, or cut it short and cap it with a wire nut.
What happens if you put a non dimmable LED in dimmer?
If you install a non-dimming LED bulb in a circuit with a dimming switch, it will likely operate normally if the dimmer is at its 100% or fully on. Dimming the bulb, will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb.
Can you put a dimmer switch on LED lights?
A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.
Does it matter which wire goes where on a dimmer switch?
Unless the new dimmer is specifically marked with LINE and LOAD or similar, it doesn’t matter which wire goes to which screw/pigtail in a simple two wire switch or dimmer. Since your new switch can be used as a three way, the instructions should say which screw should not be used.
What are the 3 wires on a dimmer switch?
Single pole switches will have 3 wires: a hot lead wire, a ground wire, and a traveler wire. Older homes may only have a hot lead and a ground wire. If you have less than three wires, stop and call an electrician.
Why are my dimmable lights not dimming?
One of the most apparent reasons for dimmer switches not being able to dim all the way is the lack of compatibility between the dimmer and bulb you have used. There are dimmable bulbs and non-dimmable bulbs; if you were to use a non-dimmable bulb with a dimmer switch, it wouldn’t work out at all.
How much does it cost to have a dimmer switch installed?
How Much Do Dimmer Switches Cost? Dimmer switches cost between $10 and $35 on average, although some higher-end models can be more expensive. On top of this, installation costs can be between $100 and $200, depending on the service and your location.
How do LED dimmer switches work?
Dimmer Switches work by reducing the power delivered to your light bulb. They do this by trimming a section of a waveform, either on the leading edge or trailing edge of the wave. Manufacturers have designed their LED light bulbs to be compatible with the majority of common ‘trailing edge’ household dimmers.
What does L1 L2 and C mean on a dimmer switch?
Dimmers look slightly different to standard switches being much more chunky. They usually come supplied with a common(C), Line out(L1) and Line out(L2) terminals similarly to a two way switch. Sometimes all three terminals are in a row.
Does LED dimmer need ground?
New dimmers have either a green grounding wire or a green ground screw that you’ll have to connect to a grounding source if one is available. If testing reveals your box isn’t grounded, you can still install the dimmer, but you must use a plastic cover plate and make sure no bare metal parts are exposed.
What happens if a light switch doesn’t have a ground wire?
For a normal light switch, the ground is a safety feature, not necessary for operation. You can leave that screw unconnected if you don’t have a ground wire, or if you have the wire but no screw on the switch, you can ground the switch another way.
Where do you connect the ground wire?
When running a ground wire, it should be connected to the designated place on the device, and then run to a safe location where the energy can be dispersed. This typically means having the wire lead into the earth, which is where this type of wire gets is name.
