How it works

From part number to submittal

01

Enter your part numbers

Type any component part number — circuit breakers, fuses, MCPs, contactors, disconnect switches. We check manufacturer data first. Unknown parts get AI identification.

02

Get verified SCCR ratings

Manufacturer-verified data comes back instantly. Every result is labeled: Manufacturer Verified, AI Estimated, or User Entered — no ambiguity on your report.

03

Download a stamp-ready report

Generate a professional PDF with your logo, PE stamp, engineer credentials, AFC compliance verdict, full BOM, and signature line — ready for AHJ submittal.

04

Share directly with your client

Generate a branded download link for your client — no email attachments. They click, they get the stamped PDF. You see when it was downloaded.

Inside the app

From BOM to stamped report

Build your panel, see the limiting component, check AFC compliance, and download a submittal-ready PDF.

Features

Built for panel shops and electrical engineers

Everything you need to calculate, document, and deliver SCCR work.

Instant part lookup

Search 64,300+ manufacturer-verified SCCR ratings across 60 major brands (Allen-Bradley, Square D, Siemens, Eaton Bussmann, Schneider Electric, Eaton, ABB, Littelfuse, and 52 more). Includes series rating combinations — upstream fuse + downstream device — so you can raise your panel SCCR without swapping components.

AI-assisted identification

When a part isn't in our database, AI identifies the component and provides an SCCR estimate — clearly flagged on your report so you always know the data source.

Stamp-ready PDF reports

Reports include your company logo, PE stamp, engineer credentials, full BOM, enclosure SCCR, limiting component, and signature line. Professional and submittal-ready.

UL 508A / NEC 409.22 compliance check

Enter available fault current (AFC) and get an instant compliance verdict — green COMPLIANT or red NON-COMPLIANT — with the comparison printed directly on the PDF.

Multiple enclosures per project

Add unlimited enclosures to a single project — main panel, sub-panel, MCC section. Each gets its own SCCR calculation, component list, and PDF section.

Saved parts library

Bookmark any part to your personal library and add it to future projects in one click. Build your go-to list of verified components over time.

REST API access

Enterprise teams can integrate SCCR lookups directly into their ERP, BOM tools, or custom workflows via a simple REST API with key-based authentication.

Org parts database

Enterprise orgs maintain their own verified parts library — custom components, proprietary assemblies, or field-confirmed ratings shared across the entire team.

White-label reports

Remove SCCR Hero branding from all PDFs. Use your own logo, brand color, report title, and footer. Reports look like they came directly from your firm.

Upgrade suggestions

When your panel fails the AFC check, SCCR Hero shows you exactly which component is the bottleneck and lists verified higher-rated alternatives.

Project templates

Save any panel build as a template and spin up the next similar job in seconds. Enterprise teams share templates across the whole shop.

Client delivery portal

Send clients a branded link to download their stamped report. No email attachments. Tracks when it's been opened. (Enterprise)

Submittal tracking

The AFC pass/fail on the report is exactly what I need before stamping. Limiting component is obvious every time.

Licensed PE · Texas

Org parts let us store field-verified ratings once and the whole team gets them on every job. Worth it for Enterprise.

FAQ

Common questions

Short Circuit Current Rating (SCCR) is the maximum fault current a panel can safely interrupt. UL 508A and NEC 409.22 require industrial control panels to be marked with their SCCR. If available fault current at the panel exceeds SCCR, the installation is non-compliant.

Stop doing SCCR by hand.

Every panel shop and PE doing UL 508A work needs this. Start your first project in under two minutes.
