I am new here and a novice comparatively but have a good question.
I work aboard an Italian built 240 single-phase 50hz boat. In Panama the boat was outfitted with a "power atlas" which is an electronic, step up/down, frequency converting, transformer. In an application where no frequency conversion is necc. A vessel usually uses an isolation transformer. the ground from the dock power supply would be "case grounded" to the isolation transformer that is electrically isolated from the entire vessel. My current installation has no ground wire at all connected from the dock. Additionally on the output module of my Atlas the power is neutral ground bonded. The vessel is in the water and the neutral ground bonding becomes the vessels bonding system connecting to all D.C. negative and bonded to all metallic objects below the water. I see a ground fault scenario causing major risk of shock while connected to shore power. Am I just wrong.
