What panelboard provides electrical power for air handler 3 in Room 018?

To determine which panelboard provides electrical power for air handler 3 in Room 018, it is essential to refer to the specific electrical layout or panelboard schedule within the technical drawings related to the project. The correct panelboard should be indicated next to the air handler in the detailed electrical schematics.

The choice indicates that P2-BF2-4 is the designated panelboard for air handler 3, suggesting it is either specifically labeled within the drawings or that the wiring and circuit layout in the documentation distinctly shows that power routing from this panelboard goes to this particular air handler.

Choosing this option implies familiarity with how panelboards are identified in the drawing set and an understanding of how electricity is distributed in the building's electrical system. Often, numbers correspond to specific circuits connected to equipment, and recognizing those identifiers is crucial for effective reading of electrical schematics.

In summary, P2-BF2-4 has been identified as the correct source of power due to its direct association with the air handler in the electrical system and corresponding documentation. Knowledge of the drawing conventions and operational relationships between different components can clarify why this panelboard is correctly identified as connected to air handler 3.
