Which item is NOT typically found in a drawing's title block?

• A. Wiring codes
• B. Sheet number
• C. Issue date
• D. Project name

Answer: (A)

Drawing title blocks carry administrative information about the drawing, not the technical content. They typically include the project name, sheet number, issue date, who drew or approved the drawing, scale, and related metadata that helps manage the set of drawings. Wiring codes are technical references that specify how conductors are identified, colored, or arranged in circuits. Those details belong in the actual electrical diagrams, legends, or separate wiring-code tables, not in the title block. That’s why wiring codes aren’t typically found there. The other items—sheet number, issue date, and project name—are standard in a title block because they help organize, reference, and track the drawing within the project and revision history.
