Panel Directory & Load Calc

Build the two electrical documents the job needs 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 stay on the phone so an interruption does not erase the work.

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.

Lifetime Pro
Export standard and optional dwelling load worksheets, export the existing-load worksheet for EV charger or heat-pump additions, and choose a code edition per job. One purchase. No subscription.

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.
