You may find that the main breaker trips repeatedly but there are no apparent electrical problems. Keep track of when this usually happens. It could be that running a large number of appliances at the same time is drawing current in excess of the main breaker's capacity and resulting in an overload of your electrical system. (Often the culprit can be a relatively small appliance that uses a great deal of current, such as a blow dryer or space heater.) There are 2 solutions to this problem: 1) reduce the load on your electrical system or 2) hire a licensed electrician to upgrade your home's electric panel.
