Multiple Generator Transfer Switches on same service drop

[ezib0819]

New Simens 400 amp main panel with two service disconnects (1) 200 amp service disconnect for main residence with separate 100 amp service disconnect for ADU/granny sub panel.

Owners wants manual generator transfer switch with generator inlet @ 200 amp service disconnect and manual generator transfer switch with generator inlet @ 100 amp sub panel.

Owner and ADU occupany could then use their own generator to power their appropriate living space in case of outage. Any concerns/red flags with two generators on the same service drop?

Don't see why not.

You must be on an older code edition, that type of service is no longer allowed. Mains must be in separate enclosures, but to your original question, there is no problem doing what you said with the manual transferswitchs.

Welcome to the forum.

I see no problem. You would simply have two of the same thing.

Simply insert a T/S in each feeder.

Wasn;t the code change just that the two mains have to be in their own compartments so if one is off the energized load side of the other isn't accessible? And of course the manufacturers were slow to redesign their products......
