The main power distribution box tripped due to lightning
Try to reset the circuit breaker by flipping the switch off and then on again: To do this, locate your main circuit breaker panel and look for the switch that controls the circuit that has tripped. Flip the switch to the off position and then back to the on position to reset it. When lightning strikes, it generates a significant amount of electrical energy. These surges occur in mere milliseconds and can overwhelm. The question of whether a lightning strike can directly cause a circuit breaker to trip is complex, but the answer is generally yes. For facility managers, electricians, and project owners operating overseas—from industrial plants in the Middle East to solar farms in Southeast Asia—these unexpected shutdowns mean costly downtime, safety risks.
