I have a contractor that is going to be wiring the new building (black outline) that is fed from a separate transformer and service. The serving utility is requiring that the service in the existing building be completely isolated from the new building. They requiring that the metal roof be broken up by a piece of acrylic roofing material, and that the concrete between the existing building and the new building creates a "neutral" plane, so that piece of concrete will have no metal in it, and a voltage gradient will be placed at the end of each slab of the two buildings. I understand the equipotential bonding of one building, however not sure if i agree with the serving utility in this particular instance. This is for a dairy farm in the state of Iowa. Keep in mind this is ag which is exempt from inspections, hence the 2 services, the utility is requiring the inspection of the bonding.
