Re: Kohler 30R82-91402A
Sometimes you donít have to derate at all for single phase output, but it depends on the generator end. If you derate by 2/3 (about 21kva) youíre safe.
In the past, on kohlers, all Iíve had to do to change the generator wiring config is to reconnect the generator leads and adjust the voltage adjustment pot until the output voltage is correct. I havenít had to make big changes to accommodate the voltage regulator. On your set, Iíd try making the wiring changes and seeing if you can just adjust your way to proper voltages. Going from 208v to 240v should be within adjustable range. Itís when you go from 208/240 to 480 that you need to be careful, usually.
