Kohler 8.5 [RE-wrenches]

[John Blittersdorf, Cent. VT Solar & Wind]

Allen,
   Thanks for the Kohler fuel consumption figures.  Looks like a gallon an 
hour at the max continuous settings.  4000 watts per gallon... now to check 
out my little K2200 consumption in gallons of gasoline compared to the Kohler 
with propane...  too late tonight for that math.

   You read my mind as I had wondered about breaking the neutral bond on that 
generator.  Is it as simple as isolating the neutral wires from the ground 
lug on the bottom of the wiring/circuit board space?  

   Which brings up another odd situation I had.  A Honda 5000 watt generator 
feeding a DR1524 suddenly started kicking the ground fault breaker on the 
generator after working fine for months.  I had not broken the ground/neutral 
in that generator and had not grounded the generator.  I did have the ground 
(third) wire in the generator power cord connected to my main system 
ground/neutral point in the transfer box.  We couldn't find anything wrong 
with the power cord and finally I tried disconnecting the ground wire in the 
power cord at the neutral bus and it worked fine.  All I could figure is that 
the snow that had blown in around the generator in its makeshift shed was now 
grounding the generator case and creating dual grounds.  The system ground 
rod is only a few feet from the generator.  Should I just ground the 
generator to that same rod...creating a common ground or is the correct 
grounding to isolate the neutral in the genny and reconnect the ground wire 
at my main bus.  At the time I didn't think to connect the genny frame the 
the ground rod to see if the problem went away.
