Breaker Trips After lIghts on 30 minutes
Dennie, my first guess is there is something on this circuit you are missing. Look carefully for this time of year a little electric heater, or new tv, or appliance. My next guess again for this time of year and where you are is moisture from exhaust fans or roof is getting into the lights causing some power shortage and load. If you are fully sure there is nothing else on this circuit then move on. If not sure then turn the breaker off a while and see what is not working.
But if anything is bad you named then my first guess is bad breaker. My next guess is the dimmer switches. If you will turn the lights on for a few minutes and just lay your hand on the breaker and dimmers to see if you pick up noticeable heat you maybe found your problem. Now the breaker will be hot if there is excess load on it. You have a main breaker that will totally cut off the box. You should be safe to cut off the box, remove the wire (simple screw tighten on all I have seen) and switch the wire from the breaker tripping to another one of same amp rating. That is stamped or molded into the breaker itself. Then cut back on every thing and do a test. If that does not trip then replace breaker, if it trips then place wires back into proper breakers.
Of course the easiest way is if you have an amp meter that clamps around a wire then just clamp it around wire at the breaker. If the load (will read in amps) is less than the breaker rating and it trips, then bad breaker. They will fail so don't be surprised if a bad one. If you do have amp meter turn off all (even unplug) every thing you know of on that circuit. Plug back in or turn on each item by itself and check the load. Then have all on at the same time.
You probably have either a 15 or 20 amp breaker on a lighting circuit. In the perfect would a 110 wattage bulb in a 110 volt circuit is ONE amp load. If I am reading correctly you are no where near that load in those lights. If you have only 600 watts on there you are about 5 1/2 amps or about 1/3 of a 15 amp breaker. If that is truly all the load you have on it and it is tripping there is a short but not a "dead" short in that circuit.
As to the lights cans you should be able to access them from the light side. The electrical part normally is any way. BTW, not hung any pictures lately have you?

Good for you. And such low cost.
