Built by the trade, for the trade

One model of your electrical system. Accurate on day one, current in year ten.

Upload photos of your panel schedules. Circuits, breakers and loads become linked panels with NEC 2023 load calculations, not spreadsheets.

Same record, different job

Contractors build from it, designers check it, owners keep it.

  • Contractors

    Check the design, build it, and leave the record behind.

    Test a change against real panel capacity before anyone pulls wire, and keep the record current as the job moves.

  • Designers

    Big-picture load numbers before the drawings are done.

    Demand and capacity in minutes, calculated the same way on every panel — and a change propagates and recalculates after each save.

  • Owners and maintenance

    A clean record of your building, not a binder.

    The current information about the panel you are standing in front of is one scan away — its circuits, its load, and what it can still carry.

What works today

All of it is live in the app now.

Build

  • Now

    AI Import

    Upload a photo of a panel schedule. Circuits, breakers and loads come back as an editable schedule, with the source photo one click away.

  • Now

    Assemble in minutes

    Start from as-builts, or build from scratch. A panel photographed on site and a panel typed in behave the same afterwards.

A printed circuit directory inside a panel door, covered in marker corrections: circuits printed as Spare are crossed out and renumbered by hand, with rack and UPS notes written in the margins.
A water-stained circuit directory with torn edges, its entries handwritten and several crossed out.
A faded photocopy of a typed as-built schedule for Panel D, 120/208 V, three-phase, listing each circuit's load in VA on phases A, B and C.
A CAD-drawn schedule for Panel L17, 480/277 V, with circuit numbers, breaker sizes and a bus-connection diagram showing which phase each circuit lands on.
What's on the door, and what came with the job.

Analyze

  • Now

    Calculate

    NEC 2023 load calculations — headroom, utilization, phase balance — update with every saved change.

  • Now

    Check and assess

    Check the drawings you are building from, or assess the design you are drawing up. A panel change carries through to the panels feeding it.

Manage

  • Now

    Equipment register

    Panels, transformers, switchgear, generators, transfer switches, motors, equipment loads and the utility service in one list, with nameplate details where the plate carries them.

Share & keep current

  • Now

    Label

    A QR code on every panel and asset opens a read-only sheet. Scanning needs no account.

  • Now

    Print

    PDF panel schedules, ready to hand over or tape inside a door.

  • Now

    Directory cards

    Printed panel directory cards with the panel's QR code, one panel at a time.

A panel directory printed by ampacity.ai for panel B, 208Y/120 V, three-phase, 225 A bus: 42 circuits in two columns, each with its breaker size, and a QR code that opens the live schedule.
What we print, straight from the model.
The warning card on a panel in ampacity.ai, reading: 2 issues on this panel. Over capacity — utilization 91.3% exceeds threshold 80.0%. Imported load differs from the calculation — the schedule footer printed 148.9 kVA connected; the calculation gives 300.7 kVA, 50.5% apart.
Check and assess: the panel's own warning when the imported total and the calculation disagree.

Scan the panel, read the current record

A printed code inside the door, and a phone in front of it.

Taped inside the panel door — scan it, no account needed.

Testing and inspection: scanning is live today, with no account. The rest of that workflow is coming soon — see the ledger.

The same record, current — not the faded 2009 print-out.

Why ampacity.ai

  • Built by someone who does the work

    Steve Ashburner, P.E., licensed in California, with 20+ years in design and construction. He got tired of designing in complex engineering software and constructing in Excel.

  • Stop retyping

    Import the schedules you already have instead of keying them into a spreadsheet.

  • One linked system, not linked spreadsheets

    Once panels are connected, a saved breaker change updates the schedule, the load calculation, and the panel feeding it.
