Just a quick question. I don't know much about electricity, so here it goes. I got an apartment where there is no grounding. In fact, there is no grounding for the whole building. I have 110v and 220v appliances installed. Do I need to be worriede about potential electric shocks? The apartment is on the 6th floor, so it could be really hard to install a proper grounding wire.

Any suggestion will be appreciated.

Thanks.
