Ashamed cannot remember but haven't messed with this stuff since my stroke. Putting 2-prong plug on big old heavy-duty drop cord. Searched web and it only referred to green plus red and black. I think my black is positive but i am not sure. Facing the 3 prongs, it is obvious which prong is ground (green) but the left and right prongs confuse me. Which gets the black and which gets the white? Please help me. Need to use it today. Thank you in advance.Electric wire color coding: green is ground but what is black and white?
Look at the spots where the wires go. You are right about the green, of course. The black is your power, and white is neutral.
The screw heads on the plug will have a green painted one for the ground, a silver colored one for white, and the brass or copper colored one is for the black wire.Electric wire color coding: green is ground but what is black and white?
Black is hot, white neutral. Hook up the white to the wider of the two prongs (left), black to the narrower one.
black is hot. white is nuetral. green is ground.
Good answers so far. One thing to watch out for is polarization. If the male and female plugs have one slot (or prong) that is wider than the other, it's where the white wire should be attached.
