What is the appropriate action known when specifying the location of receptacles in a blueprint?

The appropriate action when specifying the location of receptacles in a blueprint involves mounting height determination. This is a crucial step as it ensures that receptacles are installed at heights that meet both functional and code requirements. For example, the National Electrical Code (NEC) provides guidelines on the minimum height for receptacles to facilitate accessibility for users, ensuring that they are reachable and usable without obstruction. Correct placement also takes into account the design and layout of the room, considering furniture placement and use of space.

While identification of supply sources, labeling of circuits, and correct wiring methods are all important aspects of electrical design and installation, they are not specifically about the spatial placement of receptacles on a blueprint. Therefore, focusing on mounting height is essential for electrical safety, usability, and compliance with codes and regulations in the building plan.
