Hi. Both receptacles below are rated 20 Amperes for USA :
This one does not accept a typical plug :

This one does :

What appliances have plugs for these outlets ? Never seen a vacuum cleaner, microwave oven, coffee maker, clothes iron, clotheswasher... equipped with such. What are they meant for on a dwelling with these wired to a 20A circuit breaker ?
And the reverse; if you install a 20A circuit breaker with these receptacles above and AWG12 wiring... What is their typical usage ?

The top one is for 240 VAC. The two horizontal slots are for 15 A plugs and the vertical and horizontal slots are for 20 A plugs.
