How should appliances serving different areas of a building be marked?

• A. Permanently marked in an approved manner that uniquely identifies the appliance and the area it serves
• B. Relocated as per the current code
• C. Clearly identified
• D. Within a mechanical room

Answer: (A)

The main idea is to ensure there’s a durable, unambiguous link between each appliance and the area it serves. Appliances that serve more than one area must be permanently marked in an approved way that uniquely identifies the appliance and the area it serves. This kind of labeling stays with the equipment for the life of the unit, withstands physical wear and environmental conditions, and gives technicians a clear map of which space will be affected by a given unit. It supports safe isolation, maintenance planning, and code compliance because you can quickly trace service events or shutoffs to the exact area involved. Simply labeling the unit or relying on a location like “in a mechanical room” doesn’t provide a lasting, specific connection to the area served, and relocating the equipment or using vague identification wouldn’t meet the requirement. A durable, approved label that names both the appliance and the specific area it serves is the practical, compliant approach.
