> but unlike the extension cord case, nothing would catch literal fire I might be taking this too literally (I fell down the Kunsberg Bridge rabbithole recently), but with only one input on nearly all extension cords, I don't see how you'd get into a position of "fire" rather than "nothing happening". Even if you did have two ways of putting power into your extension lead, it wouldn't necessarily lead to fire; household "ring" circuits (still very common in UK houses) are by definition a loop.
