IDing Utilities

Anyone know of a good (preferably free) video or even a .pdf that has a pictures and descriptions of the various visible utilities that are often asked to map?  I'm sure it varies by region to a certain extent, but I'm looking for something pretty basic-- like the difference between a standpipe and a riser, or a transformer and a sector box, or how to tell the difference between a traffic signal cabinet and... any other kind of cabinet, or the difference between a vault, junction box, or pull box.  The list goes on.
