We have a house built in 1965 that I'd like to install GFI receptacles
in as an added safety precaution for our 15-month old. We have
three-prong grounded outlets with copper wiring, but on many of the
receptacles I cannot get the outlet cover off (they are metal and
there is a center screw). Are these likely just painted on, or did
they make a one-piece box and cover. Assuming the former, any
suggestions for separating the cover from the receptacle?

IIUC a GFI trips, disconnects the hot wire, if the ground wire is bad,
no longer connected to a ground.
Let's assume at the start the ground is good. This means if you are
using an electric drill with a metal case, and internally the hot wire
inside the drill touches the case, which will be connected to the
ground prong on the plug, the current will go through part of the case
to where it connects to the ground wire, instead of going through you.
And if the ground wire in the receptacle becomes bad, the receptacle
or the circuit breaker will trip and there will be no power to the
drill in the first place. Even if it has no internal short.
Unless your baby is using power tools or other apppliances with a
metal case, and a 3-pronged plug, I don't think a GFI will help him.
What you want is that he not put something metal in the hot slot of
My brother and I never did that. Maybe we weren't allowed to have
metal things small enough to go in. We had no plastic covers. No one
did. But it's good to be cautious and I think those would be better,
and cheap, and easy.

I remember sticking hairpins in 'em. Than I got a little older and I stuck
the leads of a NE2 neon lamp in a socket and it burnt the leads off.
Eventually learned that a bare neon lamp needs a current limiting resistor.
