Ryan,

Looks like the GFCI, would cost a little more then the waterfall.
Great story, good read.

It's a 1,200 amp, 3phase GFCI that's designed for "personnel protection"? Does that mean that it has 5mA trip level, I thought that was impossible. And if it doesn't, how is it still for personell protection...? [Linked Image]

Cool story.

Bender makes some rather unusual GFI units, including ones for DC and high frequency AC. No doubt they can make such a thing as a 5mA 1200A GFI.

We use one model to detect faults on 1000 Hz systems. It is configured for the European level of personell protection, 30 mA, but I don't think there is anything to prevent it being made for the American 5 mA level instead. The unit comes with a separate "donut" and doesn't have a rated current, only a maximum fault current. (14 kA if memory serves me)
