Nope, doesn't matter. You can pull all single phase loads off of a 3 phase panel without a problem.interesting! Fuel to the fire
I have nothing here that requires 3 phase, in fact we have nothing here that requires 240V! Even our well pump is 120
I would not ever be using a 3 phase load through that panel
Does that matter?
I see it looks like the 3rd phase down the middle contacts the breaker spots with the screws in them
So if I put some 120 loads on L1, some on L2 and some on L3 you are saying it would be pretty well balanced
very interesting! Learning as I go
In industry that is done all the time. Panels that are dedicated to lighting circuits are all single phase loads even though the panel itself is 3 phase.
Don't overthink the balancing too much either. If you stay within the rated load for each phase the generator does not care. Balance it the best you can if you need MAX power but don't get carried away over it.
