I think you should look up the regulations that apply to your home country if you want the answer to this. The IEE 'Wiring Regs" are a good reference for the UK.

This really is about 20 pages of info and background - can you ask one specific question and I am sure plenty of the members here would be eager to discuss, but this is is just too random.
