How does this work? Does it need to be one without ground?
GFCI has a switch that is tripped if there's a leak of power. It's the outlets that have a test button between the two plugs. It essentially is just an outlet with a breaker that is tripped if it's shorted so it can't cause any harm. Basically, if the incoming current isn't the same as the outgoing current, it trips and shuts off power.
But does using an extension cord disable this protection?
It does if you plug it into an outlet without the protection.
