Hi Michael, This is a very difficult question to answer as it could be a myriad of issue's. The simplest answer is that the electric trips when a surge is detected, and the simultaneous switching of both bedroom lights and kitchen lights pushing the expected demand from the circuit over the breaker size (usually 6A). This is also usually down to the property of the bulbs being used, as they may have a large initial demand when turning on before settling down to a normal level. The cheapest and easiest solution is to change the bulbs in the affected rooms with lower wattage/rating bulbs and see if this fixes the issue. If you have multiple downlights in either room consider changing them for LED equivalents as they are less demanding. If the bulb changes doesn't work then you are looking at problems with either your fixings or wiring which would need proper diagnostic investigation be a qualified or competent person. Kind regards, Matt ELCERT
