Originally, I wanted to 'add' a receptacle in my old Despard switch 'array' stack. Now I am puzzled and afraid of doing that because I found out that the original 'neutral' wire was tied/screwed to the electrical metal box, and of course, there was no ground wire installed.
Some outlets in my house are not grounded. (though I see long tails grounded wires coming off the house to the pipes outside of my house). I just don't know why isn't the entire house grounded.
Q1: Is it safe if I just leave the 'neutral' wire screwed to the box like before? (because I am afraid that I couldn't install a receptacle)
Q2: If I wire the 'neutral'(silver) and 'hot' (gold) to the new receptacle (bottom position), will it work?
Q3: If Q2's answer is yes, then do I need to ground the new switch?
Q4: Should I wrap that lonely neutral wire so it won't touch the metal box? I just couldn't figure out why would my previous owner 'ground' a neutral wire?
Thank you very much. right now, unless I fully understand what is going on, I don't want to install anything. My house is old, I don't want to start a fire.
