"Another often misunderstood concept is that a GFCI needs a grounding connection (note the "ing" on the end of ground). It doesn't. All it needs is a neutral (ground) and a hot wire feeding it. The fault is detected and set when current in the two feed wires is unequal, indicating that another current path is being followed - perhaps through you! This makes a GFCI even more desirable when a separate grounding connection independent of the circuit ground is not available. "
Professor,
went to answers.com looked up GFCI. they tell us that it is a breaker of sorts but it is not a overload protection device. as far as needing a ground thank you for reminding me, I had a blond moment. NEC tells us that expanding existing work without a grounding conductor the first device must be a GFCI. you are right and I am wrong on the grounding thing and I should know better.
the windings in the genset are wound for single phase, it is single phase in 110 and 220 so the phases are in line no matter just a matter of wireing in parallel or series. No I didn't put them on the scope to view the phase, just took what I know about motor windings and transformer windings and brought the wires into conformance with what it takes to run in parallel. please note that motors that are dual voltage have there winding brought out to the conection box. in the case of a single phase genset you could label the windings from left to right as 1(black)2/3(yellow)4(red). if you split the 2/3(yellow) and then run 2(yellow) to 4(black) and 3(yellow) to 1(red) you then have a 110 only machine. the number of conductors inside the unit are 4 this is because they used smaller magnet wire than required for the output and paralleled them. If you would like to post diagrams I will send them to you, I don't know how to post. and don't have a page. also the libility scares me.
