As near as I can tell after reading the rules, this question IS allowed, but it's borderline, so let me be very careful how I set this question up.
COMBINING TWO OUTPUTS FROM SAME GENERATOR
1. If the answer is no, if there's no way to do it safely, then that's the end of it. I might ask clarifying questions so that I can learn something, but I have no desire to win a Darwin award.
2. To the best of my knowledge, each winding is spun by the same engine output shaft from the gasoline engine, but they are out of phase.
3. These are the two outputs I want to combine:
Generac GP17500E - 60hz
Neutral bonded to frame
One 125/250V
50amp - 14-50R
One 125/250V
30amp - L14-30R
4. We are now reaching the limits of my electrical knowledge.
5. I know that in theory two or more power sources can be combined but it may be that the equipment necessary to do so (Rectifier? Transformer?) is sufficiently complex and /or expensive that while it may be possible, it is also impractical.
6. The ONLY reason that I am even bothering to ask this question is because although the windings are out of phase (am I saying that right?), they at least aren't driven by two different engines. Therefore, I BELIEVE that I need to resolve a phasing problem but not a variability problem.
7. The motivation is to be able to supply the full 77 amps of power from the generator to my panel at the same time. I basically have a transfer switch setup, only it's one of those panel faces that won't let you close the main breaker and the back-feed breaker at the same time. It essentially forces the breakers to be in an opposite state where one is open and one is closed. It doesn't matter WHICH is open or closed, but the physically can't both be in the same state at the same time.
My backup plan is to replace my panel with a setup that separates out the HVAC from the rest of the house circuits and then just use two patch cords; one for each of the 120/240 outlets.
And by the way, the Generac literature refers to the generator as being 125/250 but it's rated at 120/240.
Why? I don't know. Bad proof reading maybe? Voltage at my household outlets is generally in the 125-127 range.
I only mention this because I noticed it but didn't know if it was pertinent.
