Re: Electrified Water
I would say it can become electrified as soon as it comes into contact with live electrical wires. The size of the wire doesn't matter.
In your case, it could be the pump (if the pump is running). Otherwise, it would be the pressure switch if that's lower than the outlets. Definitely when it hits the outlets it can become electrified.
Do not assume that the fuse will blow or the circuit breaker will trip as soon as the water hits it. The conductivity of water is dependent on its purity. Pure water is close to being an insulator, but any impurities in the water may make it a conductor. Salt water can be a very good conductor.
You may want to consider installing a main breaker in a location that isn't subject to flooding. You may also look into installing either a passive drain or a sump pump. If you have a flat, level lot, the passive drain -- exiting somewhere on your property below the level of your basement floor -- may not be possible.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
