Schematic of 480/277 distribution system

[MIEngineer]

Hello All,

Not too long ago I think I remember seeing a document that included a nice schematic of a 480/277 volt commercial building distribution system. The drawing even included the lighting panels and receptacle panels.

Does anyone elese remember seeing such a document recently? or have any in their possession that you wouldn't mind sharing? I am not very artistic and could make something crude but would much rather have it look pretty as well as informative.

Thanks you,
