I need to install a diva low voltage electronic dimmer. An incandesent dimmer was previously installed. lights flickered. There are 4 wires on the dimmer. (green black whate and yellow) I know what to do with the green black and whate, but What do I do with the yellow wire in the low voltage dimmer?

The power supply for the led's may not be dimmable. Not sure if this dimmer is for led but I assume that's why you bought it.

Transformer hum with dimmers is a problem. Lutron may offer you an inductor to add to the wire to help. Replacing your 50w bulbs with 12w LED bulbs may help, too. Same light output.

Dimmer gone bad.
Buy new dimmer.
Check total wattage of bulbs, and compare with watt rating of dimmer.
Check if dimmer feels warm
reduce watts in ceiling linghts

No, they're not supposed to be flickering, regardless of the light-level. I can't think of why a power outage would cause the lights to flicker all of a sudden. My first suggestion, check the lamps - make sure they're incandescent or line-voltage halogen lamps. If they're CFL or LED, then flicker (particularly at low-end) isn't just possible - it's likely. Other sources of flicker - sometimes the power companies install new metering equipment that throws some jitter on the line that cause issues - not much you can do about that unfortunately. My primary suggestion is to call tech support at 1-800-523-9466. It's free, they're available 24/7, and can probably offer more suggestions than what's available through doing this over a web-site.

If each fixture has an individual transformer, the chace is that they are electronic (about the size of a matchbox car) If so, you have the wrong dimmer installed. You will need to install a MAELV (Electronic Low Voltage) Dimmer. The regular dimmers are set up for Magnetic Low Voltage and incandescent which work differently. http://www.lutron.com/TechnicalDocumentLibrary/362219.pdf

Here is a link to the difference in how they work. Also, if they are a Low Wattage light like an LED, the dimmer may not have enough resistance to bleed off the excess voltage. The MAW-600 has a minimum load of either 25 or 40 watts. If you are operating LED's you may also need a Low Wattage Interface to act as a simulated load that wires in series with your lights. (lut-lbx)

If it gets too anoying until you get the proper dimmer, you can switch the Air Gap switch at the bottom to the off position. This completely disconnects the power to the load side of the dimmer.

Good Luck

If each pendant has an individual transformer that is about the size of a hotwheel then you need a dimmer specifically for ELECTRONIC LOW VOLTAGE. A lot of electricians don't know that the different types of lights require different dimmers. Most store bought dimmers are for incandescent lights only, and some nicer dimmers like the Lutron Maestro's are rated for incandescent or MAGNETIC Low Voltage which require a different Sin wave interuption. I don't know that leviton makes a dimmer in that style for Electronic Low Voltage. You could install a Lutron DVELV300P-Wh, but that is a Decora opening. http://www.lutron.com/CMS400/WorkArea/downloadasset.aspx?id=25437
Here is a link to explain the difference in how the dimmer needs to work. Good luck!

No it means you have a short somewhere in the wireing. disconnect the power unhook the switches and use an ohm meter to test the wires to see if you have contact between the wires, black to white and black to bare ground wire. if it's a three way wire test all of them, if you used tsaoles to hold it in place check where you put the staples in you may find you have a staple ran threw two wires. Or if you pulled the wire and pulled it around a hard corner you may have pulled the insolation off somewhere the above test will confirm this. This is assumeming you are testing line voltage without a step down transformer or any other device in the circut

You cannot use standard electronic dimmer switches with CFL bulbs, only incandesant bulbs! That is why you are getting the flickering.

With CFL's bulbs installed in a light fixture that has a non-flouresant rated dimmer switch on that circuit, you will cause the standard dimmer to fail.

You have to look at the dimmer package (sometimes printed on the back of the dimmer itself too) to see if it can be used with CFL bulbs,as many are not rated for use with anything other than standard incandesant bulbs.


Hope you found this very helpful and best regards!

The Lutron Maestro dimmer isn't rated or designed to operate low voltage lighting as it is a 120 V-AC rated electronic dimmer. You should either install a standard low voltage ON/OFF switch on this installation or obtain a dimmer rated for use on low voltage lights.

You need special low voltage dimmer designed for use on the low voltage pucks lights you have installed. Usually the low voltage is either 12, 24, or 36 volts, depending on the manufacturer of your particular light set. Once the correct dimmer is in place, the problem with the flickering and pulsing of the lights, should cease.

If you still are having this problem and you can't find a low voltage dimmer, you can contact the maker of your low voltage light kit and they can provide you with an acceptable dimmer option for your lights.

Most Home Depot and Lowe's carry the low voltage puck light kits, and usually have accessories for these lights, including dimmer switches that will work with them.

Hope you find this Very Helpful and best regards!

PS: I found this old, unanswered question and wanted to provide a solution to close out the problem and clear the question from the site.

Consider using a MAELV-600 and a MA-R. The MAELV is rated for 600W Electronic Low-Voltage. The MAELV will require a neutral wire connection.
