External factors that can cause an electric surge include weather conditions, trees, and animals. Instead, a power flash is caused by electrical discharges from damaged electrical equipment, usually downed or severed power lines. Assume its live and dangerous, even if the line isnt sparking, humming or dancing.. Tripping breaks the continuous pathway of the breaker and renders the circuit inactive. The buzzing sound that power lines produce is caused by a phenomenon called corona discharge. For example, if your light switch is rated at 10 amps but your circuit is rated for 15 amps, it will result in an excessive load.
