Hello,

I have installed 3 chandeliers and 6 wall lights (27 bulbs all together 60W each) under one double dimmer swich (chandeliers under one and wall lights under the other) but they burnt after a while being turned on.

Does anybody know if I need a transformer to make it work and what kind? I would really appreciate all ideas.

Thanks
 
1/ If these are ordinary 230v incandesant bulbs then what would you propose using a transformer for?

2/ What is the total wattage on each circuit?

3/ where is the burning taking place, lights or dimmer? POSSIBLY BAD CONNECTIONS

4/ what is the working current of the dimmer? EITHER TOO LOW OR FAULTY

5/ If all these bulbs are on a single lighting circuit to both dimmers and lit at the same time then it's probable that the circuit is being overloaded
 
HI,
I would lower the wattage of the bulbs, i.e 20w bulbs. so 20w x 15=300w and 20w x 12=240w. You can get 400w and 250w dimmers that would work ok. Your currently very overloaded for the dimmer module. Or mix the 20w with 40w bulbs, but balance them out evenly for the dimmer ratings.

What do you think guys ??

Roman chances are your dimmer switches are rated at a lower wattage ie dimmer switches are rated at 500w and your 1st circuit is coming in at 900w (15 lamps at 60w = 900w) and 2nd circuit coming in at 720w (12 lamps at 60w) so if your dimmer wattage is lower than your circuit thats why it's burning out.

Two ways to solve this either get dimmers that are able to cope with the wattage of each circuit or Lower the wattage of the lamps to suit the dimmers, I would go with the 1st one if it was me mate.

I will go with the first suggestion, as my dimmer has already burnt. Thanks for your advice!
