225.30(A) says you can have additional feeders or branch circuits for emergency and standby systems. Is that one per system?

If you have a generator transfer panel in building A, can you run multiple branch circuits to building B? (using up to 6 disconnects per 226.33).

Part 'a' of your inquiry...I venture yes, to one of each. In a real situation, it could be a tough sell re: 'standby' & 'emergency' details.

Part 'b' IMHO is 'yes', but I want to research more for confirmation!

This sounds like a 'George' question??

Meaning????

#1 It's a good question?

#2 George should respond with an answer?

If you mean the latter, I would say that the generator could serve anything you want it to with a priority to the emergency circuits. I don't know what will trigger the generator to start - hopefully the failure of the emergency circuit(s) and if there is an overload on the generator, it must be designed such that it will shed the non-emergency loads. IMHO

George:

Meant......

#1, Yes, a good question, much like yours.

#2, Your answers are always welcome, and you are good as stirring the pot.

You make good points.

Load shedding was what prompted the question. If you had load management in building A controlling loads in building B, I can see why it might make things easier if you could run multiple circuits.

The more I think of it, you would probably be better off running low voltage signaling circuits to the second building and have local control but that doesn't address the original question.

Hurricane season started today so I am getting more generator questions from my friends here.
