The pool must be bonded with the solid #8 to the motor, and any other metal within 5' of the pool must also be bonded together. One of our local inspection agencies require that if the pool is bolted together, only one lug is needed to attach to the ribs, if the pool is screwed together (I haven't seen any), then every other rib is required to be bonded. Our AHJs accept lay-in lugs with sheet metal screws. Sand away the paint, apply Nolox and use a lock washer.
