Eaton Arc Fault/GFCI combo breakers fail to trip when tested with a downstream GFI tester, causing inspection failures and uncertainty about compliance.

Standard GFI testers do not reliably trip Eaton combo breakers, but the breaker's own test button works; electricians lack a reliable field test method to verify downstream GFCI protection for inspections.

Workarounds Described

pushes test button on the breaker repeatedly (like 15,000 times) to get it to trip with a GFI tester
installs a GFCI downstream of the combo breaker and hopes it doesn't cause nuisance tripping

Implied Software Gaps

A diagnostic tool that reliably tests combo breakers by simulating real faults rather than relying on standard GFI testers

App Concept

BreakerCheck Pro

A handheld tester designed specifically for AFCIs and combo breakers that simulates a real arc fault and ground fault, triggering breakers that standard testers miss. It provides a pass/fail indication and logs results for inspection documentation.

Key Features

Arc fault and ground fault simulation
Compatible with Eaton, Siemens, Square D, and other major brands
Pass/fail LED and audible alert
Bluetooth logging of test results to smartphone app

Target Users: Electricians and electrical inspectors in residential and commercial construction

Revenue Model: $199 per unit one-time purchase; $9.99/month for app with cloud storage and reporting
