The answer to 'why is my electrical panel tripping breaker' is that a tripped breaker is a common issue with several potential causes. Tripped breakers are the electrical panel's way of protecting your home from power surges, short circuits, or overloaded circuits.
Some common reasons a breaker may trip include: too many devices plugged into one circuit, a short circuit in a wiring or appliance, a ground fault, or a malfunctioning breaker. When a breaker trips, it cuts off power to that circuit to prevent damage or fire. To restore power, you'll need to reset the tripped breaker by switching it fully to the 'off' position and then back to 'on'.
