This is the concern of everything electrical, and is why there is an EGC; and why wasn't that event prevented by the EGC of the washing machine's cord and circuit opening the fuse/breaker?
Let's take a 100 watt light bulb and place it between the hot and the EGC. I doubt that it will take out the fuse/breaker. Do you want to grab the faucet and washing machine at the same time under these conditions?
