The mains that you are talking about sounds like a breaker to me if it tripped off automatically. These days main breakers are rated in the 100 to 400 amp range depending on the size of the house. This is a overcurrent device that trips on a short circuit. They don't shut off without a reason. What was being done at the time of the trip. Renovations? If you can elaborate a little further I might be able to pinpoint the cause.

Which IS a common sense safety procedure that can help prevent electrical accidents?

What is main function of switch?
The main switch fuse box is there to help prevent electrical fires. If you overload a circuit, and it tries to draw more current than the wire is supposed to have, it will pop the fuse, causing an open circuit, and electricity stops flowing. The main switch allows you to disconnect all electricity coming into the home. Otherwise, the current would heat the wire to the point where it would burn/melt the insulation, then the bare wires would start the house on fire. Not fun if left unattended.
What alteration would occur if a single pole switch is reconnected to become a master switch?
If a single pole switch is wired to be a master switch, the switch would have to be in the on position for any other control devices to operate. Turning the master switch off would eliminate power to all devices (and/or loads) which it was serving. For example, some homes have a switch to control their outside light. If the outside light has a photo eye (the light will only come on at night), the switch is the master switch. Another example would be the breakers in an electrical panel. Each breaker would be the "master switch" for the circuit it protects. The main breaker in the panel would be the "master switch" for the entire home.
