The one thing that most people seem to ignore is the hazard or electrical appliances. Any outlet that you use in the kitchen, be it for a crock pot, toaster, electrical skillet or whatever, should have a Ground Fault Circuit Interrupter (GFCI or GFI) in the circuit. If you have a short, this will break the circuit quickly. This is especially true if the outlet is anywhere near the sink.

I am surprised that the electrician did not mention this as it is now a part of the code in many areas.
