Asking oneself how many breakers can I put in a 100 amp panel is an excellent method to become familiar with one's own housing electricity. Depending on how the 100- amp panel was manufactured, you can install breakers between 20-24 (minimum) and 30-42 circuits (maximum).

How many circuits are in a standard house?

The diagram clearly indicates that the 'average house' has two power and two light circuits. A single power circuit for a whole house could easily get overloaded to the extent that it would be tripping on a regular basis, i.e. ~3800 watts of devices on the one circuit would trip it.

How do you reset the main circuit breaker?

Reset the main breaker by turning the switch off and on two times. Leave the switch in the on position. Return to the breaker panel inside your home and turn each breaker back to the on position, one by one. In many cases, power is now restored.
