What a panel schedule does

A panel schedule is the map of a distribution panel: every circuit number, what it feeds, the breaker size, the phase it lands on, and the load it carries. It is what an inspector, the next electrician, and your own crew read to understand the panel.

This builder lays out the schedule with correct left-right circuit numbering and phase assignment, so the document matches how the panel is physically wired. You can then print or save it as a PDF for submittals and as-builts.

Worked example

For a 42-circuit three-phase panel, you enter each load against its circuit number and the builder places it on the correct phase following the odd-left, even-right pattern. A 20 A kitchen circuit on position 1 lands on phase A; the tool balances and totals the load per phase so you can see if the panel is loaded evenly.

Why it matters

Panel directory and circuit identification are required by CEC Rule 2-100 and NEC Article 408.4, which call for a legible circuit directory that accurately describes each circuit. A clean schedule is both a code requirement and the document everyone relies on later. This tool produces the document; it does not reproduce a code table.

Common mistakes

Frequently asked questions

What is a panel schedule?

A panel schedule is a document listing every circuit in a distribution panel: the circuit number, what it feeds, the breaker size, and the phase. It is the reference an inspector and future electricians use to understand the panel.

Is a panel schedule required by code?

Yes. A legible, accurate circuit directory is required by CEC Rule 2-100 and NEC Article 408.4. Each circuit must be clearly described so the panel can be understood and worked on safely.

How are circuits numbered in a panel?

Odd circuit numbers run down the left side and even numbers down the right, with phases repeating in a fixed pattern. The builder places each load on the correct number and phase automatically.

Can I export the panel schedule?

Yes. You can print the finished schedule or save it as a PDF for submittals, permits, and as-built records.
