How to use a single‑line diagram template.
- 01Choose a template or start fresh
Pick a pre‑built distribution panel example from the gallery, or open a blank canvas in the SLD editor.
- 02Build the bus and main breaker
Add the main bus, incoming feeder, and main circuit breaker. Select voltage rating and phase configuration.
- 03Add branch circuits and feeders
Drop in breakers, fused switches, or motor starters. Connect feeders to downstream panels or loads.
- 04Annotate ratings and cable data
Label breaker amp ratings, wire sizes, and conduit types. The tool auto‑aligns text for a professional finish.
- 05Export and share
Download as PDF, PNG, or SVG. Share a view‑only link with your team for review.
Questions about single‑line diagram templates
What is a single line diagram for a distribution panel?
A single line diagram (SLD) is a simplified schematic that shows the electrical flow path through a distribution panel. It uses standard symbols to represent busbars, breakers, and feeders, omitting unnecessary detail about conductor routing. SLDs are essential for design, coordination studies, and arc flash analysis.
What information should a distribution panel SLD include?
At minimum, include the panel voltage, phase configuration, main breaker size, branch circuit breaker ratings, feeder destinations, and cable sizes. For larger installations, adding prospective fault currents and equipment interrupting ratings is recommended.
Can I generate a panel schedule from this SLD?
Our tool focuses on the diagram itself, but you can use the annotations to later fill in a panel schedule. The SLD you create shows the distribution structure clearly, making it easy to transfer data to a schedule sheet.
How do I show multiple feeders from the same bus?
Simply drag additional feeder lines from the busbar symbol. You can label each feeder with its breaker size and destination panel. The editor keeps the diagram clean even with many branches.
Is the diagram editable after I create it?
Yes, all examples and generator‑created diagrams are fully editable. Return to the editor anytime to update ratings, add circuits, or change layout.
