If you notice that you have a particular circuit on your electrical panel that tends to trip again and again, it might mean you simply have too many appliances or electrical devices running on that same circuit. If you don't have many devices running on that particular circuit, or you notice that the problem is still occurring after disconnecting some of them, it could mean you have a faulty breaker, in which case you're going to want to call in an electrician to repair the issue as soon as possible.
