By the way, on an "almost related" topic, I once read of a simple thermostatic control device that was installed in a system (specifically, an oxygen tank) for which the voltage exceeded its rating. It was a matter of incorrectly choosing which device to install, and nobody noticed the mistake. Later, they ran a routine procedure to remove moisture from the tank by heating it. The thermostat failed, since it was being operated at too high a voltage. As a result, the temperature in the tank got too high. That caused the insulation in other wires installed inside the tank to overheat, and to melt away. Nobody noticed that either. Still later, when the tank was in actual use in a real mission, the operator tried to perform a routine stirring of the oxygen within the tank. The wires chose that moment to short circuit, and the oxygen tank exploded.
The book in which I read this story was called, ?Lost Moon,? and was written by the commander of that particular mission. His name is Jim Lovell. They gave him a 5 second ?bit part? at the very end of the movie they made from the book. The name of the movie was ?Apollo 13.?
What is my point? When something eventually fails, somebody is going to find out how and why. At that time, they are going to ask why, when someone knew the breaker was being operated beyond its rated voltage, that someone didn?t do something about it. A simple action taken early enough would have prevented the failure, and the injury/fatality (heaven forbid it comes to that), and nobody took that action.
