What do american plugs look like? As in power plugs. 99.9% of UK plugs are look like this and come in either 3Amp, 5Amp, 10Amp or13Amp Varieties.: There are some different shaped 15Amp ones, but these are rarely found in domestic homes. But what do American ones look like, cause I'm rather confused, there seem to be so many?? EDIT: Electrical plugs btw.
