Dear Forum;
Does anyone know if it is permissible to provide power from a house panel from an adjacent building to another building. I have a landlord that wants to power the FACP of the building with a dedicated branch circuit from an adjacent building. The fire alarm panel will be mounted on the outside of adjacent building in a NEMA 4x enclosure with an AC unit. There will be two branch circuits from the house panel on the adjacent building ran to the FACP, one for the AC and one for the FACP. The house panel that is mounted on the adjacent building does not serve any appliances inside of the building it is attached to. The house panel provides power to parking lot lighting and common area appliances that are not within any building. The branch circuit from the house panel in building A is not co-mingled or in any way near any branch circuits from tenants or house power in building B. The house panel for building B is 300 feet away from the FACP and the house panel for the parking lot lighting is 40 feet away from the new FACP needed on to protect the riser that is on the outside of the building.
1) Is there a code that prohibits the powering of an appliance mounted on the outside of an adjacent building from a house panel that is not mounted on the same building.
2) If the house panel did have branch circuits serving inside of the building it is mounted to, does that change anything?
3) Can a house panel serve more than one building?
4) Is this any different than if the landlord wanted us to install a light and mount it on the adjacent building and feed it from the house panel that does all the parking lot lights?
Thanks
