Unlike standard switches, most dimmer switches have wire leads that are connected to the circuit wires with wire connectors, rather than using screw terminal connections.
Do dimmer switches need special wiring?
Remember: Dimmer switches don’t work on most fluorescent fixtures, and low-voltage lighting requires special low-voltage dimmers.Remove the wires from the old switch. Dimmer switches are usually connected to the house wiring by short lengths of wire coming out of the switch body rather than by screw terminals.
Can you wire a dimmer switch wrong?
What can happen when you wire a smart light switch wrong? The switch may not work. If you do not connect the switch to the neutral wire, the switch will not have a power supply. It would thus not be able to listen for a command of turning on or off.
Does it matter which wire goes where on a dimmer switch?
1 Answer. 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.
How is a dimmer switch wired?
With conventional dimmer wiring using NM cable, a NM cable supplies line voltage from the electrical panel to the dimmer outlet box. Another NM cable connects from this dimmer box to the light fixture box. Both line and neutral travel from the switch box to the light fixture box.
Can I replace a regular light switch with a dimmer?
Instead of merely turning lights on or off, get a wide range of light by installing a dimmer switch. Most dimmers are designed to fit a standard wall box opening, which makes it easy to replace the switch for any incandescent or halogen light with a dimmer.
Can you replace a dimmer switch with a regular light switch?
You can replace the dimmer switch with a regular light switch, only from what you have described you need to install a 3-way light switch, not a single pole light switch. The typical connections are as follows: The black wire to the lone screw on the 3-way light switch.
What happens if ceiling light wired incorrectly?
Tip. The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.
What happens if you wire a dimmer switch backwards?
But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
Which wire is hot on switch?
black wire
Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
How many wires do I need for a dimmer switch?
Attaching the dimmer switch to the circuit wires extending from the box is fairly straightforward since it usually involves just two hot circuit wires attaching to two hot wire leads on the switch. A second black (sometimes red) wire on the dimmer attaches to the other black circuit wire in the box.
Which wire is hot when both are black?
Place the prong of the multimeter’s black wire on the bare metal on the end of a white wire, then read the meter. If you get a reading, the black wire is hot; if you don’t, the black wire isn’t hot.
Which wire is hot when both are same color?
black
In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means.
Can you put a dimmer switch on fluorescent lights?
Dimming fluorescent tubes
FYI, fluorescent lights do not dim well at all.Furthermore, it takes the correct type of dimmer switch, like those made for incandescent or led lights won’t work with fluorescent lights and a fluorescent light fixture that’s rated for dimming.
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.
Can you install a dimmer switch on any outlet?
Dimmer Switches Should Not Be Used on Outlets
A dimmer switch varies the voltage of the wired light fixture in pulses to make the light from the fixture brighter or dimmer. This variation can cause malfunctions in other electrical devices that are plugged into the same outlet.
Why does my dimmer switch have 2 black wires?
The two black wires connecting to the black leading to the switch are supplying power to the switch/dimmer. The blue wire from the switch connected to the other black wire is the switched-hot going to the light. The green wire is the ground. It all looks normal.
What are the different types of dimmer switches?
Most dimmers fall into these four bulb type categories:
- Incandescent and halogen bulbs.
- Dimmable compact fluorescent light bulbs.
- Magnetic Low Frequency (MLV)
- Electronic Low Frequency (ELV)
What happens if you mix up black and white wires?
It will produce a big spark and hopefully blow a fuse or trip a breaker. If you wire them together and then turn the power on, the spark will occur at the breaker or fuse. Either way, don’t do it.
What happens if you reverse hot and neutral wires?
One common issue with electrical outlets is reverse polarity, also known as “hot-neutral reversed.” In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your electrical items, it is also present a greater shock hazard.
Which wire is hot black or brown?
The protective ground must be bare, green or green-yellow striped. Hot (active) wires may be any other colors except these. However, common practice (per local electrical inspectors) is for the first hot (live or active) wire to be black and the second hot to be red.
