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.
No and no one said it would
You can just rip off the grounding prong to bypass the protection. I keep having to fix cord ends because too many dipshits at work can't be bothered to look at the at what they're doing when they plug something in.
Not if the extension cord is into the GFCI outlet. It doesn't care what's plugged in. It's similar to a circuit breaker. It doesn't care what's drawing power, only how it's being drawn.
