The answer to 'why is my circuit breaker circuit overload' is that a circuit breaker trips when the electrical current flowing through it exceeds the maximum safe level. This can happen for several common reasons, such as too many devices plugged into the circuit, a short circuit, or a faulty appliance drawing too much power.
When a circuit breaker trips, it cuts off power to that circuit to prevent damage or fire. This is a safety feature, but it can be frustrating when it happens. To resolve the issue, you'll need to identify and address the underlying cause of the overload.
