Training for offseason tommorow, blew the Main circuit breaker. cause for worry?

If the main breaker gets too hot, it will blow. Using all those motors on a 130 pound *without batteries* robot most likely just over stressed it. Was the practice longer than a normal match? The length might have made the breaker get too hot, blowing it.

Some teams that use 6 motor drive trains take a can of compressed air turn it upside down and blow over the breaker to cool it down between matches. This seems to help with preventing blows.
