I recently installed a monorail lighting kit in my home office; I wanted another spot-light which meant I need to swap out the included transformer to something that would allow more than 100 watts.
I now have the issue of random breakers tripping. When this light is turned on. (I did not have this problem w/ the original transformer)
It seems that when my closet light in my bedroom (on a different circuit) is turned on; and my new office light is turned on, my bedroom circuit is blown 100% of the time.
Here's the weird part. I can have my master bedroom light on or my master bathroom light on and all is well. The instant I turn my master closet light on the whole bedroom circuit fails. Not only that, it will sometimes trip other random breakers, like the washing machine breaker ..or the downstairs kitchenette breaker. I have two breaker boxes, my master bed circuit resides in box 1.. but can somehow trip a breaker in box 2.
As far as my home-office circuit; it's never tripped. But, it is the only common denominator I have. For the time being; I need to ensure that if my wife is getting ready in the bedroom (walk-in) closet that my home-office light is off.
