A simple task, I know.



No always, and the newer GFCIs sure are wide in a box.

I always wrap a strip of black electrical tape (its politically incorrect
these days, but I've always known it as "jap wrap") around the
outside perimeter of the GFCIs, covering both the screws
on the hot terminals and both screws on the neutral terminals.

I make sure there is no, zero, da nada, zippo, bare wire at the rear
holes / terminals on the hot and neutral legs.

I take some green tape and wrap a single turn of the green,
separately around the "Line" black wire and "Line" white wire,
so I don't later have to do a lot of testing / guessing about
which incoming wires in the box are "line" and which are
"load" if, as always seems to happen, I have to replace the GFCI
10 years from now.
