Type N

There are two variations of the Type N plug, one rated at 10 amps, and one at 20 amps. The 10 amp version has two round pins that are 4 mm thick, and a grounding pin. The 20 amp version, used for heavier appliances, has two round pins 4.8 mm in diameter, and a grounding pin. The Type N socket was designed to work with Type C plugs as well.
