Question about Electrical Supplies
I have installed a 3 gang grid dimmer, with 12 spots on one switch (grid 750w), 6 on another (500w) and 9 on another (500w). The dimmer with the 9 spots has blown twice. once without warning and then a light bulb exploded and the switch wont work anymore. Any ideas on how to fix without replacing the dimmer for the second time in 3 weeks?
In addition to an individual rating per dimmer, these dimmers have a total recommended rating based on the size of grid used. Assuming you've got three in a double box - the total combined load is 1000W of tungsten or 700W of LV fittings. It looks to me like your trying to dim too much in a limited space and generating too much heat.

Also look at what your dimming, if it's gu10 lamps these can downrate your dimmer by as much as 50% in some cases. Check with the manufacturer to be sure.
And the above post is right, you'r way overheating the dimmers.
Look intogetting a remote pack, or for a cheaper option replace lamps with a lower wattage e.g 35w.

Too much load? Disconnect some spots and see what happens.
