Need to replace the plug on a battery charger due to someone breaking off
the grounding prong, and am not absolutely certain on how to hook up the
other two prongs. I know that black is hot and white is neutral, but does
the black go to the left prong (normally a little "wider" than the right,
but not on the replacement I bought) and white to the right, or reverse?
Somebody please enliighten me, before I plug this thing up and damage it.
The wider blade is the neutral, narrower, hot.
On a polarized plug, as well as the wider blade the screw terminals
should show a color change that is discernible as lighter/darker.
Facing a receptacle w/ the ground at the top, the neutral is to your right.

I don't think what you stated is correct. The best way to get it
right is to always connect the BLACK wire to the *narrow* blade. The
WHITE wire to the *wide* blade and the green wire to the round
The way I remember this is that by making the narrow blad thee hot
blade, it means you can't push the wide blade which should not be hot
into the hot slot, so it's safer.
Despite how much sense this makes, 20 years after figuring this out, I
still get confused.
Guess you are talking about the US wiring. Hook the black wire to the brass
colored screw and the white wire to the silver colored screw. The green
goes to the green screw which will be the round prong.
You will not damage anything if you do switch the black and white wires. It
just will not be as safe to use. Usually not a problem for someting like a
