Nema L5-20R wiring diagram has me confused and looking foolish

[Installer]

The Nema L5-20R receptacle diagram ( click on the hyperlink) shows a System Ground, Equipment Grounding Conductor and a Hot Conductor.
See the "W" next to "SYS GR"? See the G next to the "EQUIP GR"
I'm a bit confused

When I go to wire this up my, where does my Green conductor going from the Panel go?
Where does my White Conductor (Neutral) go?
Where does my Equipment Bonding Conductor go?

I see this as an unfortunate choice of words by the manufacturer.
Equipment Ground is a "shorthand" for Equipment Grounding Conductor, which does not carry normal circuit current, and excusable.
"System Ground" for what is actually the Grounded Conductor, often a neutral, and showing the ground symbol as if it were a current carrying part of the circuit is just, IMHO, inexcusable.
If the diagrams come from NEMA rather than Leviton, somebody should be complaining.

I agree it's confusing. Typically X-Y-Z are the ungrounded or hot conductors, W is the neutral conductor and G is the EGC. Also for twist-locks the EGC usually has the "L" shaped slot.

the ground wire goes on the pin that looks like a candy cane or "L" (left side of the diagram at 9 o clock), the neutral goes on the small pin at 1, the hot goes on the larger third pin at 5.

Eta: based on the diagrams the original poster linked

Thanks!

Thanks!

Thank you all very much. I'm at home Saturday spending personal time putting together a set of Procedures for an installation. Didn't expect to get such professional feedback so quickly.

You're welcome. Note that plugs will be wired as a mirror image of receptacles so that all of the connections line up properly. Actually, the wires go to the same terminals on a plug, it's just that the plug face is a mirror image of the receptacle face.

Remember that pretty much all modern receptacles will have brass screws for the hots, silvery/white screws for the neutral/grounded, and a green screw (should be obvious ). Some parts even have similar colored paint around the conductor holes.

(Surprising that I can't find any photos online of the back of the receptacle, too lazy to take one myself.)

Good points, zbang.

The only other thing I would add to an instruction manual or set of procedures is that when wiring a plug, you have to be pretty exact with where you cut the jacket and the wire lengths otherwise you will have unjacketed wires sticking out of the strain relief out of the back of the plug

Locking plugs/connectors and locking receptacles typically also have ungrounded terminals marked X, Y, and/or Z, grounded conductor marked W, and EGC marked G. Not all 5 markings are always present - depending on intended configuration of the device.

All of these suggestions have been incorporated into the procedure

Also.... pick the right end of the cord for that device*. Seems obvious, but I can't count how many times I've forgotten to look and had to cross one lead under/between the others, and that's always after wiring the end where it doesn't matter.

*at one end of the cord the wires will appear as White Black Green (clockwise); at the other it'll be Black White Green (also clockwise). Match that to the device's physical rotation. It's easier to explain with a picture.
