How many dimmers on a circuit

In this setup, the light level is controlled from a single location, whichever light switch you replace with the dimmer switch. If you can find a 4 - way dimmer switch , you could replace any 4 - way switch in a multi- way circuit with it.

Otherwise, it's either got to be the first or last switch. You can only have one dimmer per group. You can put the dimmer at either location, but not both locations. There are "companion" dimmers available from some companies, that allow you to place additional dimmers in the circuit. How much does it cost to install a dimmer switch?

The more expensive dimmer switches often include features such as a decorative styles and finish options. It is also important to consider the labor and supply costs that are required to install these switches.

What makes a light dimmable? Detect from the source voltage the light level that an individual wants, and then give that light level. Do dimmer switches need to be grounded?

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. Can I use a 3 way dimmer in a single pole application? Yes it can work. Just pick the correct two contacts and you are good to go.

In the first position, the contacts are connected straight through, so that the switch has no effect. Four- way switches are used to control lighting from three or more locations.

Four- way switches are used in combination with three- way switches. There are four terminals that provide two sets of toggle positions on a four - way switch. When the switch is in the up position, the current can flow through two terminals.

The main limitation to the number of recessed fixtures you can run at the same time is the rating of the circuit breaker that controls the circuit.

Standard dimmer switches should never be used to control the fan motor on a ceiling fan because the dimmer could damage the fan motor, or overheat and start a fire. A safe repair can be as simple as replacing the dimmer switch with a standard toggle switch , but you also lose the ability to dim the light. Published on Nov 18, The Type A three - way switch has three terminals; a four- way has four. These control a light from two or three locations, such as in a stairwell, at either end of a hallway, or in a large room with more than one entrance.

A dimmer switch controls a light's intensity. Usually you can replace any single-pole switch with a dimmer. If the light turns on, the second black wire you connected to the switch is the switch feed and the unconnected black wire is the feed to the other loads.

If the light doesn't turn on, then it's the other way around: the connected wire feeds the other loads and the disconnected wire is the light feed. The single switch controls a single light or lighting circuit. These are often used on a stair case, large room with switches by each door. They are wired so that operation of either switch will control the light. Dimmers are devices connected to a light fixture and used to lower the brightness of light.

By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Modern dimmers are built from semiconductors instead of variable resistors, because they have higher efficiency. Replacing a standard single-pole or three-way switch with a dimmer switch is no different than replacing a standard switch. Remember: Dimmer switches don't work on most fluorescent fixtures, and low-voltage lighting requires special low-voltage dimmers.

Turn off the power to the switch at the circuit or fuse panel. There is no limit of how many dimmer switchers you can fit in one circuit. You can also have two dimmer switches operating one light. Agnews Electrics. Dimmer switch are usually rated for watts , so you can replace every light switch in your house with a dimmer switch , as long as each dimmer switch does not see a load more than watts.

I recently got my house re-wired and in the lounge I have two sets of low voltage 24v spotlights. One circuit has 12 x 50 watt Hi, Please could some one help with a question about a double dimmer switch. On the inside of the switch box, it says W max I wanted to a remove one of the downlights, and Ask a tradesman. Hi, Is it true you can only have One dimmer switch per circuit? Thank you! Like 2.
