Which wire goes with which post?
Not really wanting to do this twice on this extension cord plug replacement. I have a green, white, and black wire. Thanks in advance.

When you are looking at the face of a female plug or a wall outlet, the left opening is the ground or where the whiter wire resides. The ground (white wire) slot is slightly longer than the hot, (black wire) side. The right side is the hot side or where the black wire resides. The bottom opening between the two is the safety ground and where the green wire should be attached.

That not a "plug".
That's a "receptacle".
A receptacle is female.
A plug is male.I can clearly see the silver and gold screws in your photo.The SILVER screw is for the WHITE wire in the USA. It's the "neutral" wire.The GOLD screw is for the BLACK wire in the USA. It's the "hot" wire.The GREEN screw is for the GREEN wire in the USA. It's the "ground" wire.The same for a "plug".

Pay no mind to the color of the screws in the picture. The 2 vertical slots are going to be for the white or black wires. Usually the white wire goes to the silvery screw and the black would go to the other side. The underside or doghouse hole is the ground wire (which in older wiring setups is the Green wire) in other cases the ground wire is bare wire as ground does not carry a charge. That is how that is hooked up. Maybe by this companies way of thinking...silver screw for white and green is darker than silver so the dark screw for the black wire.
There is some logic they had in choosing the green screw up top as there is no hard fast mandatory rule how they do it.
. Some other ends do not have a difference between the screws in color coding. It is the way it is.
. With AC current it really does not matter, which is white or black. It would only matter on DC current.

on the plug you should have a brass or gold screw, a silver screw and a green screw. The black wire goes to the gold or brass screw, then the white wire to the silver screw then the green or bare wire to the green screw. All done =)

Take the cover off of an outlet on the wall and copy the connections you see there.

white goes to silver, black goes to gold green goes to green
The mouth is the ground, the larger slot is the white, the smaller slot is hot/black.

when the colors are not obvious [or the piece is older and being reused], the lower center "D" shaped terminal [hole] is the ground. Then, as you look at the holes in the plug, the slot on the left, which is slightly larger, is the neutral [white wire] and the one on the right, which is slightly smaller, is the hot [colored black or red] terminal.
all 110v systems in North America use this coding and arrangement.Source(s): grampa

The black (hot) wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw. This wire is sometimes red. The green or bare copper (ground) wire, if the device has one, attaches to the green screw terminal on the switch or to the electrical box. Follow this for guidance

green goes to ground or the round post, black is hot and goes to the gold or bigger post and white goes to the silver or smaller post.

Look at the screws on the plug. They are 3 different colors. The brass one goes to the black wire, the lighter color/silver one goes to the white wire and the green screw is the green ground wire.
