PANEL SCHEDULES

A panel schedule laid out like the panel itself.

SINGLE LINE DIAGRAMS

Draw one-line diagrams without a CAD package.

Build a single-line diagram from an electrical symbol palette with drag-and-drop connections, starter templates and a title block, and keep it in the same project as the load calc and panel.

Try SLD Editor →

Take it to the panel. Check it at the desk. Hand it over.

One project, not three files

Keep the load calc, panel schedule, photos and diagrams together in one project instead of separate spreadsheets and drawings.

Paperwork that is easy to check

Reports lay out the inputs, demand factors and totals, so you, your client or a plan reviewer can follow the math. Always verify local requirements with your AHJ.

Field and office

Use it on your phone at the panel or on a desktop back at the office.
