I'm lazy today. Too lazy to get up and scan the UL standard pictures on
receptacles and plugs. Here's some URLs for Midwest Electric the most
popular source of RV park pedestals. These happen to require a separate
post.

and
http://www.midwestelectric.com/products/gs/product.html?model=U075GP6
are pedestal style.

show 20, 30, and 50 amp receptacles in their most common environment.
The 15 amp receptacle doesn't have the T shape on either blade hole. The
15 amp 120 volt blades are parallel, the most common US receptacle.
