Boat galvanic isolator

Zincguard prevents galvanic corrosion caused when you install a shorepower system on board your boat. According to latest BMEA and CE regulations, the AC earth from shorepower must be bonded to your anode. As the boat next door also has the same bonding system, the shorepower earth wire is essentially connecting all underwater metal parts on each boat together. Both vessels are sat in water that acts as an electrolyte causing an electrical cell (rather like a very low power battery). This will cause 'weaker' (or metals with a lower galvanic number) to transfer to 'stronger' metals, which means your sterngear could easily end up electroplating next door's boat or the pontoon! Zincguard is fitted in the incoming AC shorepower line. It interrupts any galvanic circuit but still maintains earth continuity for safety.
