Are you saying that the condo owner does not have access to the service disconnect? Is there full time maintenance personnel?
230.72(C) Access to Occupants.
In a multiple-occupancy building, each occupant shall have access to the occupant’s service disconnecting means.
Exception: In a multiple-occupancy building where electric service and electrical maintenance are provided by the building management and where these are under continuous building management supervision, the service disconnecting means supplying more than one occupancy shall be permitted to be accessible to authorized management personnel only.
