well, I pulled the cable taught before I tightened the comp. fitting, so if you pulled on the cable hard enough you would have to break the silicone seal (tenacious stuff) and then rip the wires from behind the screws, then pull the ground wire out of the lug. If after all that you were still pulling, then yes you would trip the GFCI or breaker because of the wires shorting out. Personally I am still doing a 3 tier gravity setup, so 7 gallons of hot water would pour down on me before it got to that point.
I am not saying this is the greatest/safest way to do things, It just works for me, and I think is as safe as i need to be when mixing water and electricity.
I do have to give props to the outdoor electrical box over the connections setup. I was thinking about going that way until I came upon this elbow piece for 97 cents.
edit- i actually just realized there is a safety factor built in, because the hot and neutral would pull away before the ground would, keeping the kettle grounded... like most electrical plugs where the ground is longer that the hot and neutral for the same reasons.
