Had a good discussion with a high time Learjet pilot about the potential threat of resetting DC circuit breakers. The gentlemen stated he first heard about DC CBs being a threat in Learjet ground school. He also cited Air Canada Flight 797 which had a rear lavatory catch on fire after resetting a toilet motor CB.

Another military pilot was listening in on our conversation, and we both replied that it is common practice in the military to reset a DC breaker if it was not tied to a fuel system.

Prior to researching Flight 797, I've never heard of giving a CB "time to cool", and thinking twice about resetting one unless it was critical equipment for safety of flight.

What is your take on the topic?
