Elimination of Equipment Grounding Conductor to Boat Docks Proposed for Virginia

Mike Holt Enterprises Electrical News Source

It was brought to my attention that a proposal has been submitted to the Virginia Department of Housing and Community Development (DHCD) to change regulations in the Virginia Construction Code to eliminate the requirement for the circuit equipment grounding conductor to boat docks.

I believe that this is a violation of the National Electrical Code 250.4(A)(3) and 250.4(A)(5), and the basis for that can be found in my video Electrical Safety Fundamentals. Please watch this video in its entirety (1 hour, 13 minutes), and if you feel motivated, or have any feedback for or against this proposal you can contact Nicole Donaldson at DHCD, or proponents Jim Erler or Neil Harrington.

So I'm a little confused here. Do I understand that they had (as built) the EGC connected to the Neutral at both the Dock Service Panel and the House Panel? I thought EGC to Neutral was only supposed to be at Service Disconnect? I do see what they are trying to do here and I've always wondered if an isolation transformer with its own grounding and equipotential system would be appropriate for docks, pools, etc.(of course that means $$$). You would still need GFCI. Then again, I'm an ME not an EE.

Watch my video on how the wiring is supposed to be and why. A N-G connection is only permitted at Service Equipment.
