John: It appears Alan has gone back to Audioasylum where he usually hangs out so I'll step in to answer your question. The only differences between the Hubbell 5362 and 8300 are: 1) the 5362 has a nylon face where the 8300 has a thermoplastic polyester face 2) the 8300 has a very thin layer of bright nickel plating on the power contacts to prevent corrosion/oxydization and achieve the hospital grade rating which the 5362 does not and 3) the 8300 has the green dot on the front indicating the hospital grade.
Other than that, the receptacles are identical. At the wholesale price level, the 8300 sells for about $5 more than the 5362.
Here is a link to the data sheet on the 5362-from there you can search for the sheet on the 8300:
