Everything in the U.S. is wired that way. Central circuit
breakers/fuses and anything plugged in to the circuit beyond that.
That's why they started making Xmas tree lights with fuses in the
plugs. Imagine shorting out a string of lights with a 20A breaker
feeding the circuit.
Actually, you need not short them out to be in trouble. Just hook
enough of those suckers end to end and the wiring in the first one
gets almighty hot - and perhaps incandesent. A friend did it to
himself a number of years back. Rather exciting for a while, what
with fire engines and all that. Rather embarassing later trying to
explain to his fellow engineers how it happened!
