Your main breaker may keep tripping due to several reasons. Common causes include an overloaded circuit, where too many devices are using the same circuit, or appliance faults, where a damaged appliance causes electrical leakage. Environmental factors like water or rodents damaging cables can also lead to tripping. Additionally, issues with the incoming electrical supply, such as loose external connections, may cause the breaker to trip. A short circuit, where the live wire touches neutral, is another common cause. Electrical faults in the system, such as old wiring or faulty components, can also trigger the breaker to trip. Finally, a faulty trip switch may be to blame. It’s best to consult an electrician for a detailed inspection.
