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.
When you say "blow" do you mean "trip" (i.e. just pop it back), or "fried" (i.e. something inside is irreversibly damaged)?

And yes, the practice session was longer than normal.... with a lot of anti-t-bone maneuvers... (so high amps)
