On an electrical plan, what does a circle with three lines extending from it typically represent?
Correct Answer
B) Ceiling fan outlet
A circle with three lines extending from it represents a ceiling fan outlet on electrical plans. The three lines indicate the connection points for the fan motor, light, and ground.
Why This Is the Correct Answer
A circle with three lines extending from it is the standard electrical symbol for a ceiling fan outlet. The circle represents the outlet box location, while the three lines specifically indicate the three separate electrical connections required for a ceiling fan installation: one for the fan motor, one for the light fixture (if equipped), and one for the ground connection. This symbol distinguishes ceiling fan outlets from regular ceiling outlets which would only show one or two lines.
Why the Other Options Are Wrong
Option A: Junction box
A junction box is typically represented by a simple circle or square without the three extending lines, as it's just a connection point for wires rather than a specific outlet type requiring multiple connections.
Option C: Three-way switch
A three-way switch is represented by a different symbol - typically an 'S' with a '3' subscript or an 'S3' designation, not a circle with three lines extending from it.
Option D: 240V outlet
A 240V outlet is represented by a circle with specific markings indicating voltage (like '240V' text) or a specialized outlet symbol, but not specifically by three lines extending from a circle.
Memory Technique
Think 'Three lines = Three connections' - Fan motor, Light fixture, Ground wire. The circle looks like a ceiling medallion where a fan would mount.
Reference Hint
Florida Building Code, Chapter 27 (Electrical) or NEC Chapter 4 (Equipment for General Use) - look for electrical symbol standards and ceiling fan installation requirements
