Looks like a standard 240V plug to me, three prong with one sideways to the other. Hard to tell the actual size though.
Definitely check your pot to be sure its magnetic.
My pot hangs over the sides of the hotplate a couple of inches. It really doesn't matter except if the hotplate will hold the weight. I've heard of people putting wooden spacers under the overhanging edges of the pot to hold some/all of the weight. Induction will work as long as the bottom is within 0.5" of the cooking surface, at least I've read that.
