Let me give you the short answer:
The AC "Earth" is not part of the Amel Bonding system. The two systems were designed to stand alone. However, when Amel chose the Calpeda 220VAC Saltwater pump for Climma AC, an unintended connection between the two was created because AC Current safety necessitates that the steel pump case to be connected to Earth and electrolysis necessitates that the steel saltwater pump be connected to Bonding. Since the pump and motor are steel and connected to one another, there is a crossover between the two systems.
This situation is a good reason to install a March Mag-Drive Pump rather that a pump like the Capelda 220VAC pump. Coose that March pump wisely because of the normal unpainted steel on most of their pumps. If you buy one of these do something to mitigate rust/oxidation.
