Why are you cutting the 120-volt wattage into a quarter, when it should only be divided by two?
I have/had this same connection on my honeywell generator. Which is 6875 surge and 5500 running watts.
When they wire these units with a floating neutral so that you can run 220v or 120v from the same plug in they reduce amps from the 220v 30 amp rated use to about 15 amps on the 120v side.
I took it to a generator expert because it would not run my a/c .
After testing it he said the way they wire that plug to run 220/110 there's not enough amps on the 120 side.
$200.00 later he rewired mine and took that hookie dual volt receptical out and installed a 30 amp rv in its place.
Now I have a full 30 amps 120v but no 220 volt.
We tried to wire an adapter from the 4 prong to the rv connector and it did work but only had 15 amps available.
