Now that Michigan has adopted the 2005 NEC (It's about time), the requirements for pools, hot tubs, fountains and ponds have changed. I can sure use some detailed pictures and examples of how people are conforming to the equipotential grids as required in 680. I hear many people with many different ideas on how they comply, but a picture is worth a thousand words as they say and this is one place I could sure use a few.
The 2008 is going to soften the deck requirement a bit so you may end up with a "bump" in the requirement for a few years. Florida has cherry picked that easing of the rule from the 2008 and put it in the Florida Building Code amendments so we don't have to wait for the 2008 (that will probably be skipped anyway). I haven't seen the final NEC text yet but it is supposed to be as simple as a #8 looped through the deck pour (or under pavers) as I understand it. I would hope AHJs would pick this up sooner than they adopt the 2008, just to avoid that 12 x 12 copper grid anomally for a few years
