Very simple question. Please don't ask why, it's existing situations.
Is there a problem with a generator ( optional standby, home ) feeding a automatic transfer switch and a manual transfer switch?
Let me explane.
320 Amp service, 2 - 200 amp panels.
Generator sized properly to handle 1 automatic transfer switch of 1 200 Amp panel according to NEC.
Generator also feeding a Cutler Hammer mechanical interlock panel. The 2nd 200 Amp panel.
Upon power outage and transfer the auto switch activates the first 200 amp panel.
The 2nd is manual and requires the owner to physically move the mechanical interlock to power up the 2nd 200 amp panel.
The question.
Does the load of the 2nd panel need to be calculated in any way in the sizing of the generator.
My thinking is that it is the same as load shedding and the homeowner controls the load shedding. The manual loads are not automatic and therefore are excluded from any calculations.
Any ideas?
