The situation is a bank with a detached drive through.
225.30 states that where there is more than one building or structure, that each structure must have a separate disconnect.
In your opinion does 225.32 exception 1 apply to this situation? Or should we have the panel on the structure? If the panel is on the structure, we have various issues including lighting control, the need to run various communication circuits further and so forth. (The structure is not manned and the on/off lights currently are controlled by a relay panel inside the building next to the panelboard controlling all these circuits.)
Additionally, would having all the circuits on a panelboard that has other loads be allowed? Disconnecting one breaker disconnects all the circuits feeding that structure.
As far as safety goes, I don't see that the situation is different for a drive-thru that is across the driveway than for one that is attached to the building - but of course the letter of the law must be followed.
Previous practice by other design firms has been to just run the circuits separately as though the structure was attached.
Thank you for your thoughts.
