What causes my microwave to trip the breaker?
The primary cause of a microwave tripping the breaker is usually an overload of electrical current. When a microwave operates, it draws a significant amount of power, typically between 600 to 1,200 watts. If the current draw exceeds the rated capacity of the circuit, it can cause the circuit breaker to trip as a safety measure. This often occurs because the microwave is on a circuit with other appliances or electronics, cumulatively exceeding the circuit’s limit.
Additionally, there may be other issues at play, such as a fault in the microwave itself, which could cause it to draw more power than normal. Common faults include short circuits, damaged wiring, or malfunctioning components inside the microwave. If your microwave consistently trips the breaker, it may be time to have it inspected by a qualified technician to determine and rectify the root cause of the problem.
Can running other appliances with my microwave cause the breaker to trip?
