Have you heard of bonding non electrical components? I have a hydralic pump in my pool (counter current swim machine), and while there's no power to it, they wanted it bonded to the metal frame of the pool, and then they wanted the pool frame bonded to all the other componets (pump, heater, etc)... There's even a stainless steel handle on the swim machine (it's attached to plastic, not touching any other metal), and they wanted that bonded to the rest of the system...? BTW, the hydralic lines are rubber of course... Any thoughts on that?
