What would be an acceptable method to confirm the bonding of the pool deck, metalic structural components and electrical equipment per 680-26 of a 30 year-old pool? Is using a simple analog ground resistance tester using a point to point method the way to go? The points we could check would be at the pump motor, ladders and other metalic structures. Are there any other methods? Obviously the rebar mat is not exposed. I would appreciate any input. Thanks
