DÃ®ner en Blanc: People will wear white and dine at a mystery location. But first, they ask questions. Some 400 white-clad diners converged in the Distillery District for a dry run last year of Toronto's own Diner en Blanc. This year's event, at a secret location, will be much larger.
Breakers can be defective and create a hazard. This can happen if the humidity is high or water has gotten into the panel. If a breaker is tripped and will not reset even with all loads removed from the circuit, it is advisable to check it with a voltmeter or replace it.
Motors: main failure modes are failed bearings (seized) and broken wires. You occasionally see magnets coming loose, but that's rare. If you inspect your motors regularly, you will notice failing bearings long before they seize. It's very rare to have a multicopter fall out of the sky due to a motor failure. ESCs: if you use reasonable quality ESCs, and use them below 60% of their rated maximum, they basically don't fail. Props: they break, a lot.
