Scogsgura, my goal was to get the voltage differential between neutral and ground as close to zero as possible. As you suggest, I originally thought the voltage differential might be ok for the reasons you state, but then (and this is going to open a whole other can of worms)... the reason I'm...
I work in Cambodia and have a question about isolation transformers and what one would do in my situation. Some people may also weigh in on local grounding, which past experience tells me could get entertaining. ;-)
The Setting
Here in Cambodia, we have an ungrounded power distribution system...
Keith,
It's a bit complicated, but you asked! At the moment the genset isn't running. So my laptop is being powered by an inverter, which is in turn being powered by a bank of four deep-cycle batteries (that charge when the genset is on). (Incidentally, the batteries are also powering a little...

Good point. That's highly likely.
waross,
2kw was a typo in my original post. I saw it after I already got my first response, but I knew somebody was gonna catch that. It's a 20kw genset. So yeah you're exactly right - it would be overprotected by a factor of 10...
Thanks, dpc!
That makes sense. Distance between generator and my master disconnect/master panel is literally three feet (same room). So distance isn't an issue.
Lots of things will need to be changed if we ever go to a much bigger generator (or if the country of Liberia ever joins the 20th...
Ok, simple question here. . . just need to make sure I'm not missing something obvious. I'm not a trained electrician, but I'm the best I got here in West Africa. Ha ha. This question pertains to a system supposedly set up by a professional electrician, but I suspect he wasn't familiar with the...
