oh pshaw....other than killing all of the computers and every other electrical device throughout the offices, it wasn't so bad. If I recall correctly, the fluorescent lights survived...

This. They are essentially the same thing.
And ground it correctly. If using extension cords, the generator frame acts as ground but if using a MTS, the grounding systems need to be connected as long as the neutral doesn't switch in the MTS. If it doesn't switch, it's not a seperately derived system according to the NEC and the neutral and ground don't need to be bonded at the generator.
If your MTS switches the neutral, it's now a seperately derived service and needs grounding per 250.30(A).

I see what you mean. I also note that my two tied circuits are both 20s, while one on his is a 30 and one a 20. You are saying that he could swap the 30s out for 20s? Or reduce the 15s in favor of more 20s as long as he doesnt exceed the overall capacity of the unit?
For me I had planned on matchy matchy

I had a nephew plug in a tv/ dvd to the first Miller 120 V DC gas drive I owned during an outage long ago. He was amazed at how much smoke it produced.

And all of this is exactly why I went with the direct wire/no transfer switch. I just plug in, fire up and turn off any breakers I don't want powered. No conflict over which line I can power vs which I can probably do without. All circuits in the breaker box are hot.

I do believe that the generators I own all have a ground stud to install a ground wire to mommy Earth. It beats the alternative of going through a human on the way to mommy Earth.
Having the Genny frame grounded doesn't do much with most having rubber feet. Unless you go with shock anyone that touchs the frame when you have an open netural somewhere,
Like so many folks that wire in a genny or a sub panel end up with.

Doesn't matter because the ground path isn't going from frame to ground, it's using the grounding conductor to tie into the building's grounding system and since the MTS never switches the ground, the circuit maintains a ground path at all times. The frame grounding only connects the frame to ground conductor.
Now, if the MTS switches the ground/neutral, you'll need a ground rod at the genny to maintain a ground fault path in a seperately derived system.

You could swap out any GE breakers but they also offer different models. I'm pretty sure you're stuck with one 240V circuit though as the switches for each pole are tied together from the factory. There may be another model that has (2) 2P spaces though.

If I'm reading this right, any pair can be used for 240 if wired properly, meaning that the reds from both switches are wired to the poles of the double in the main panel. So I can use 2 15s for a 30 amp circuit instead of two 20s in case I have single 20s I would repfer to sue for something else thats on a sigle 20 amp circuit.

Pneumatics, go with that
I'm still workin on my small nuclear reactor project.

With whole house backups, the choice of motors to power it becomes important. Diesel is a good choice, minimal maintenance, but adds to the initial costs. Propane is a good choice. Regular gas costs the least, requires the most periodic maintenance.

Not really. A double pole breaker is physically tied together. if one half the circuit trips, both trip off. In a scenario where the breakers are not physically tied, one can pop but leave the other live.

No, what I meant to move the handle tie bar from the 20s to the 15s, the on that transfer switch I bought those are movable.

Go Amish.... Sad part is they still buy diesel and gasoline to make the air pressure needed to run pneumatics.

Can't you just hussle up a small one from friends at Bectel or Halliburton?
