Probably the most common cause for electrical safety switches randomly tripping is damaged and/or faulty household appliances. Faulty appliances produce electrical current leakages, which create imbalances in the circuit.
Considering this, should I be worried if my breaker keeps tripping?
Don’t ignore a circuit breaker that keeps tripping. This is a sign that one of your circuits is getting overloaded on a regular basis. Your circuits are only able to handle up to a certain level of voltage. Beyond this voltage, you run the risk of starting an electrical fire.
