What happens when electrical panel is full?

How does an electrical panel work? Circuit breakers trip (that is, shut off) when the circuit is overloaded. They're safety devices, meant to prevent damage to electrical devices or to the home itself. If the breaker didn't trip and shut off the power, overloaded circuits could start fires or electrocute someone.
