What belongs on a breaker box directory
A panel directory maps each numbered slot to the circuit it controls. Slot numbers run down both outer edges of the panel, odd on the left and even on the right, and this template follows the same numbering so a line on paper lands on the breaker in front of you.
Real panels are never tidy, so the template isn't either. A standard breaker fills one slot. A large 240-volt breaker for a range, dryer, or heat pump fills two slots in the same column. Thin half-size breakers share one slot between two circuits, and a half-size pair spans two slots at half height. All four sit in the grid the way they sit in the box.
Write the circuit the way you'd describe it out loud. "Kitchen outlets (except the coffee maker)" beats "Kitchen 2" the next time someone is standing at the panel with a tripped breaker and no idea which one it was.
How to map an unlabeled panel
Count your slots
Open the panel door and count every breaker position, filled or empty. Pick that number above.
Start with what you know
The big two-slot breakers are the easy ones: range, dryer, air conditioner, water heater. Place those first.
Work out the rest, one at a time
Switch a breaker off, walk the house, and note what died. Plug a radio into an outlet if you are working alone.
Flag the guesses honestly
Anything you inherited from the old label is a guess until you prove it. Mark it Unverified rather than pretending.
The full walkthrough, including how to write labels that stay true, is in the guide: how to label your electrical panel the right way.
Label what you know, flag what you're guessing
Most people inherit a panel they didn't wire, with labels that are faded, wrong, or missing. Instead of pretending every guess is fact, each circuit here carries a confidence flag, and the flag colors the slot. A panel you're still figuring out stays honest about what's known.
- ✓
Correct
Verified. You flipped the breaker and confirmed what went dark.
- ?
Unverified
A best guess, carried over from an old label or worked out by elimination.
- !
Incorrect
Known to be wrong. Flagged so nobody trusts a label that lies.
It's the same model Tobi uses in the app, where the panel lives on every household member's phone instead of a printed card.See the electrical panel feature.
Questions about panel labels
Is this electrical panel label template free?
Yes. Fill in every circuit and print the directory without an account, an email address, or a payment. The email field is there if you would rather have the PDF sent to you.
What panel sizes does it support?
Every standard residential size from 12 to 42 slots, plus a custom size for anything larger or unusual. A panel is laid out in two columns, so the slot count is always even.
How do I count the slots in my breaker box?
Count every position a breaker could sit in, whether or not one is there today. Open slots covered by a blank filler plate still count. Skinny half-height breakers share a single slot, so count the slot once.
What is a panel schedule, and how is it different from a directory?
They describe the same thing: the list that maps each numbered breaker slot to the circuit it controls. Electricians tend to say panel schedule; the printed card taped inside the door is usually called the directory.
Does the printed label fit inside my panel door?
The PDF is sized for the inside of a standard residential panel door, and prints on ordinary US Letter paper.
Can I come back and edit it later?
Not here. This tool keeps nothing after you close the tab, which is the honest limit of a printed label too: it goes stale the moment someone rewires a circuit. Tobi is the app that keeps the panel current and shares it with the whole household.
A printed label goes stale. An app doesn't.
Tobi keeps the panel, the maintenance log, and every contractor visit in one place the whole household shares.
