[QUOTE="apprentice87, post: 353180, member: 13534"] Hi All, Out of interest, if it is 380 between phases, how is it only 120 between any one phase and "earth"?? should it not be 220, especially if neutral is tied to "earth" [the hull] Could the neutral have come disconnected from the hull, so now, it is floating about all over the place, [tis on a ship!! ha ha] dependant on the way loads are balanced between the phases?? or do ship electrics not work like that. If a ship does not have the usual OCPD's. how do they "contain" faults, you know, so that a simple fault in a gun platform for example, does not burn out miles of wiring??? [/QUOTE]
