Panel Directory & Load Calc

Label a panel and check calculations without copying a circuit list by hand.

Panel Directory & Load Calc helps electricians label a panel at the dead front, print a readable door card, and prepare a dwelling load worksheet. Jobs, panels and drafts are saved on the phone.

Panel directory, free

Enter circuit descriptions, breaker ratings, pole counts and breaker types. Common residential circuit names reduce typing. Keep the odd and even breaker grid visible as the directory fills. Print a compact door card or a full schedule with the job, panel, code edition and date.

Field tools, free

Calculate conduit fill, box fill, voltage drop, conductor ampacity and equipment grounding conductor size. Each result shows the selected edition and its section reference.

Dwelling calculations and worksheet exports

Standard, optional and existing-load dwelling calculations are free on screen. Worksheet PDF exports and a code edition chosen per job require Pro. New worksheet upgrades are currently unavailable.

Private by default

No account, ads or developer analytics. Job names, addresses, licence details, schedules and inputs stay on the device unless you create and share a document.

This is a calculation and document tool. It cites the chosen edition and section references, but does not reproduce code text, certify a design or replace the authority having jurisdiction.
