What type of diagram shows the wire size required for an installation?

Explanation:
The key idea is identifying which diagram conveys electrical conductor sizes. A wiring diagram is the one that lists the electrical circuits along with the conductor sizes (gauge), colors, and connections needed for the installation. It’s the diagram that communicates what size wire each circuit requires, not just where components go or how they look. A pictorial diagram shows components in a realistic visual arrangement but usually doesn’t provide exact wire gauges. An installation drawing focuses on physical placement, mounting, and dimensions rather than electrical specifications like conductor size. So the diagram that directly communicates the required wire sizes is the wiring diagram (often referred to simply as a wiring diagram or “a wiring diagram”).
