I've been working on a good sized boat. There are several issues:
First there is a voltage converter that doesn't convert. This device (depending upon model) will accept 170 - 520 VAC 40 - 70 Hz and convert it to 120/208 3Phase 60Hz. at 100 amps max. These are specs on the name plate. Still working with the factory to determine the issue(s). The previous owner did "something at the pedestal" and the unit failed. Pedestal meaning shore tie.
Now for the interesting part, the boat has two Kohler generators, only one is operating. The output meter on one reads 53 Hz, the other 54 Hz. The boat lighting circuits as well as the outlets are all European style at 220 VAC at 50 Hz.
Here in P.R. the marine shore tie is 220 60Hz and 50 amps at the pedestal. That too has an issue, there is a "110" three prong outlet that actually outputs 220 VAC (don't bother to ask how I discovered that).
I have never seen 50 and 60 Hz systems wired this way, have any of you? The "converter" may in fact output 50 HZ, the nameplate having been changed to protect the innocent.
I shall update this as more info becomes available. The boat has been in the Caribbean for some time, and is of European extraction.
