comment Is earthing required for a submersible water pump?
@Federico Russo: Yeap, I remember an experiment at school: two electrodes are submerged into distilled water and complete a circuit used to power an old boring 60 watts incandescent bulb. At first there's no current since the water is distilled. Then maybe a spoon of salt is dropped into water and mixed with a glass stick - the bulb immediately goes to full power.

Yes, I know that distilled water is an insulator, however typical drinking water contains salt dissolved and thus is an electrolyte.

+1, "press it down" is very important - slipping out bit damages the screw in no time.

comment How important is circuit breaker breaking capacity?
I'm not in the US and we have 220 volts, so I guess 10KA you quote is equivalent to 5KA here.

comment How important is circuit breaker breaking capacity?
Yes, I'm totally sure I quote the right figures - it can be a 20 amperes breaker that has 5 kiloamperes breaking capacity and it would be offered at a local shop somewhere between gardening stuff and ceramic tiles.

comment Can I move the main breaker and the electrical meter?
@Jay Bazuzi: Maybe, but screws in such devices are usually rather huge and overtorquing them is not that easy.
