What Is an Electrical Panel Schedule?

A Structured Record of the Circuits, Breakers and Loads Served by a Panel

An electrical panel schedule organizes circuit numbers, breaker information, load descriptions, poles, phases, connected loads, demand information and panel totals. It supports drawing coordination and helps project teams understand how branch circuits and distribution panels are organized.

Panel schedules can be developed in CAD, spreadsheet-based workflows or model-linked Revit documentation. When model relationships are configured correctly, approved circuit changes can be reflected across schedules and related views.

Schedule production must be distinguished from electrical engineering. Load calculations, demand factors, breaker and conductor sizing, protection, available fault-current review, code interpretation and final approval should be provided or verified by the responsible qualified electrical professional.

Frequently Asked Questions

Electrical Panel Schedule FAQs

Common questions about schedules, breaker data, load fields, Revit updates, source information and engineering responsibility.

What is an electrical panel schedule?

An electrical panel schedule is a structured table identifying a panel’s circuits, breakers, poles, phases, load descriptions, approved load values and totals. It may also include main-device, feeder, voltage and location information.

What is the difference between a panel schedule and a one-line diagram?

A panel schedule provides detailed circuit and load information for a specific panel. A one-line diagram shows the wider electrical-distribution hierarchy and how sources, transformers, switchgear, panels, feeders and major loads connect.

Can panel schedules update automatically when circuits change?

Model-linked Revit schedules can update from correctly configured circuit and equipment data. CAD or spreadsheet schedules usually require controlled manual coordination. Every updated schedule should still be reviewed before issue.

Can subpanel loads be carried into upstream schedules?

Yes. Approved downstream panel totals can be coordinated with upstream distribution schedules and the one-line diagram. The electrical professional should verify load calculations and demand treatment.

Can standard and custom load types be included?

Yes. Schedule templates can include project-standard load categories and custom categories required by the client. Their calculation and demand treatment should follow approved design criteria.

Can old panel schedules be recreated from PDF or scans?

Yes. Legacy schedules can be recreated in CAD, spreadsheet or Revit-compatible formats. Missing or obsolete information should be identified, and installed conditions should be verified before an as-built issue.

What information is needed for a quotation?

Share existing panel schedules, one-lines, electrical plans, panel count, voltage systems, required fields, load information, templates, software and file formats, project stage and expected schedule.

Who verifies breaker sizes, demand factors and panel totals?

The responsible qualified electrical professional should verify breaker and conductor sizing, demand factors, load calculations, protection, applicable requirements and final panel totals. Drafting and schedule production do not replace that responsibility.
