What circuit is connected to the receptacle at Column Location 1-C?

The correct answer indicates that the receptacle at Column Location 1-C is connected to Circuit 1. To understand why this is the right choice, it’s essential to consider the layout and designation of circuits within the blueprint.

In blueprints, each circuit is typically marked with specific identifiers, and those identifiers are used consistently throughout the document. At Column Location 1-C, the blueprint likely shows a connection with Circuit 1 through wire markings, legends, or annotations that clarify which circuit supplies power to that receptacle.

By examining the specific details of the circuit routing shown in the blueprint and understanding the function of each circuit, it becomes clear why Circuit 1 is the one providing power to the receptacle at that location. Often, other circuits will serve different areas or devices, and their respective identifiers will lead to confusion if not carefully interpreted. This emphasis on precise circuit identification is critical in electrical work for ensuring safety and functionality.
