b.Rated for 20 amperes only
c.Isolated-ground type
d.Tamper-resistant

Code requires listed tamper-resistant receptacles in dwellings to protect children from inserting objects into the slots. Weather resistance applies to damp/wet locations, 20-ampere rating is not universally required, and isolated-ground types serve sensitive equipment, not general safety.
