"..Equipment grounding conductors may be run back to the panels and connected to a grounding bus that is in turn connected to the hull but not to any circuit conductors..."
Bill,
I think we 're saying the same thing since this is what I meant in my last post.I didn't mean to ground the neutral...
Bill and Kiribanda,
thank you both for your helpfull advices..
I think that probably the wisest way is to keep all network ungrounded, except the 2-3 subpanels for lighting (subpanels providing all the 1-phase 230 V supply in general) where I should install earth leakage circuit breakers at all...
Bill,
first of all, thank you for your time..
I'm in Europe and the code applying is 98/18 Eurosolas (marine code). The project I'm working about concerns a small two-way RORO/Pass.
Two main generators will be at 400 kV together with a step down transformer (?/?) to create also a 240 V line...
Bill,
first of all, thank you very much for the prompt response..
do you know if the safety tripping device (30 mA) used in residential supplies can also apply in this network? I should assume that it can work, am I right?
the ground line needed for the 1 phase network (i.e. power supply 230V...
Hello,
first of all thank you for your help in advance..,
I would like to ask somebody to verify me the following:
in a 3 phase 3 wire system ship power distribution, the neutral of the generator is not connected at all..
in order to power 1 phase loads though (lights etc..) a neutral is...
