Shortcircuit
The illustration in the IAEI Book only indicates that it is useless to attach a bonding conductor to the coated reinforcing steel. The Paragraph on the same page “Analysis and Effect” middle of, states. It is not required etc. Further down it states that 680.26 (B) does not specify any particular method , but 680.26 (C) (3) does cover alternate means of establishing a grid.

I would not bet the ranch on the alternate means being limited to the 3 feet under the decking on that illustration.

Section 680.26 (C) requires the grid to extend under paved walking surfaces. Is the surface you refer to paved??

If not I do not see where the language of the Code addresses grass areas surrounding the pool. Agreed it is just as susceptible to voltage gradients as a paved surface.

I still think the NFPA has some work to do. If they do not keep and eye on the MEC it is my understanding that this issue will be addressed if the NEC does not do something but then again at this stage it is all talk.
