Standby Generator Supplying Multiple Circuits

[FaradayFF]

Greetings, All-
I'm designing a setup, where a temporary genset will be supplying two circuits via a Quick Connect panel. I wanted to get feedback if it is kosher to have two circuits supplied from one source. I believe it is permitted to have a single breaker supply two different circuits. The tap rule would not apply here, since both circuit conductors ampacity would be sized to be higher than the GEN breaker. I believe circuit conductors from the Genset to the equipment downstream would be considered feeders here per NEC definition(not that it matters that a whole lot here).
Does any one see holes in this design? Please see the single-line attached.
Thanks for your feedback!

Looks like its all manual transfer switches, so is this for a portable generator?
Not enough info on the grounding?
Where is the main bonding jumper?
Is the neutral switched?

Hello,
I've updated the sketch. The main bonding jumper will be at Main CB1(considered service disconnect) for the Load 1. The backup generator is considered non-separately derived source. The genset is a 480V, frame of the genset will be grounded. The neutral at MTS1 and MTS 2 is not switched.

Thanks,
EE
