Good day, I am new on the site and I want to share knowledge with electricians specialized in conversions between European and American Electric practices, specially but not exclusive in boats, yachts and vessels applications.
This is a particular area of the profession , because boats usually have two or more electrical systems: 115~130 /210~240 VAC, 12 Vdc, and 24 VDC; all of them sharing sometimes only neutral, some other times also PE.
Metallic Vessels, as automobiles use the metal frame as reference…. But are not isolated with rubber tires, and there are aggravating stray currents, galvanic, and other leaks associated.
Plastic or wooden vessels are connected to the ocean/river/lake, via the exhaust and water entering to cool the engines and generators, and returning to the ocean/river/lake; also several metallic attachments throug the hull closing a conduction path among themselves and other boats, docks and piers.
The DC Systems are sharing the neutral with the PE, and navigation electronics suffer of interference on radars, VHFs, wifi.
Pretty interesting area where solid basic concepts enriches the common sense.
Thanks very much for accepting me on the forums.
