To answer your first question: it depends on your download speed. Not a silly answer just a correct one.
If you are trying to download on a dial-up service however then I would forget it - it could take days.
Nor sure what you mean by your wiring description either. For example what do you mean by: "wired directly into the back of my main socket"?
Try a NEW question with LOTS more information about your setup.
