• > If you plug a 16A cord to a 20A circuit and draw 20A from it, the fuse will be perfectly happy (everything's fine as far as it's concerned) but the cord can catch on fire. Technology Connections recently made a video about this. [VIDEO]

• For those who are into this kind of thing, here's a 25 minute mini-documentary of the US electrical system's history and problems. It's more focused on wiring, but has a lot to say on plugs: [VIDEO]
