What I found helped with this situation is to change the bulbs on this circuit to cfl ones as you can run roughly 7x13wat bulbs to every 100wat normal bulb. Hopefully you get what I mean. That way you cut the load down on the circuit.
the current bulbs are not incandescent. its the halogen bulbs on track lights... and the only other bulb i could get is the LED, but they're not as much light
