Any generator is limited by the mains breaker. My 45kW has a 110A/3 mains breaker.

The voltage fine adjustment is not pictured and that's where I find changes have been made by the previous user.

Voltage drop over 300ft of #16 orange extension cords?  Turn up the voltage rather than use larger wire or moving the genset.  I had one rental unit show up with the correct selection switch setting but putting out 156v on the Edison convenience outlet.  A screwdriver fixed that in 15 seconds.

Next item- NEVER trust the volt meters on the genset.  No horror story of my own but have heard enough about guys/gals mis-reading or blindly trusting them and not noticing 140v instead of ~120v.
The most memorable time was 150V to the food service trucks.  The cooks commented how FAST everything was cooking!

I was told by the generator company that many of the construction crews turn it up to get more zip out of their power tools.
