Built by the trade, for the trade

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

Panel schedules, NEC demand, feeders, loads and asset records in one model. Start from the schedules and as-builts you already have. Every edit recalculates up to the service, and every component carries its own record and a QR label.

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.
Engineering-grade, not a spreadsheet
The same NEC method on every panel, with the section behind every factor on the page. Nothing to re-derive at review.

From the first load calc to year ten

One model, three jobs. Design against it, build from it, operate by it.

Design

Engineers and designers

A complete model of the electrical system, checked as you build it: NEC demand on every panel, breaker and ampacity checks, and 60+ code and sizing rules that flag what doesn't add up. Every edit carries up to the service, and the feeder schedule and loads register stay current. Scan in the drawings you have with AI import, or start from scratch.

Now
Demand, done the NEC way
Each load sorted into its NEC category, with the right demand factors applied: lighting by occupancy, receptacles over 10 kVA, kitchens, the largest motor and compressor. Upstream, demand is recalculated over everything below it.
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
Drawing-ready schedules
Code checked and always updated from the model. Each schedule prints with its NEC load classification: every demand factor, the section it comes from and the circuits it covers. Letter or tabloid PDF.

Build

Contractors

Keep the model current through construction. Every added or moved circuit updates the schedules, the directories and the load up to the service. The same record you build becomes the turnover package, and the start of a service contract with your client.
