Title: Variac dimmer
Post by: duskb on April 04, 2020, 12:40:27 PM
Hi guys. Quick question. I'm building a new room and inherited a Staco wall dimmer but I need a couple more. I see several on ebay for various amperage but the one I have here is 10amps, which seems excessive for lighting. What is the suggested amperage for a wall dimmer powering a couple of halogen style track fixtures?

Are the halogens running at line voltage?  (110VAC?)   Or are they something else, like 12V running off an included transformer? 
If line voltage, then just add up the total wattage in the chain of bulbs and divide by 110(Voltage) to get your current (AMPS).  Leave yourself some head room.
