I have a Lutron Maestro MACL-153MH (600W incandescent/halogen) controlling 5 x H1499ICAT (low-voltage, MR-16, 50W each) in my vacation house. So, that's a total of 250W. It burned out one day, so I replaced it. After I replaced it, I noticed that 2 of the light were out and replacing the bulbs didn't help, so I figured that the housing burned out. The remaining 3 were working though. Next time I got to the house (and I actually had some time to order and replace the housings) the dimmer was burned out again, so I replaced it to see how many lights were still working, but as soon as I reset the breaker after the new dimmer was installed I heard a click coming from the dimmer and a burning smell… So, the another dimmer is gone…
Any ideas what might be wrong and what to check? Is it possible that those 2 burned out housings cause that?

The problem is 'low voltage' lights on an incandescent/halogen dimmer.
