Residential electricians are troubleshooting GFCI failures caused by EV trickle chargers, but the root cause is unclear, and customers resist installing dedicated circuits.

Electricians cannot diagnose or predict GFCI failure from EV trickle chargers; the only solution is trial-and-error replacement, and they lack a definitive answer to justify dedicated circuits to customers.

Implied Software Gaps

Diagnostic tool that measures GFCI-specific stress from EV chargers and provides evidence-based recommendations

App Concept

ChargeGuard Diagnostics

ChargeGuard Diagnostics is a diagnostic tool and mobile app that helps electricians quickly test GFCI health under EV load and generate reports. It measures current harmonics, leakage, and waveform irregularities to confirm if an EV trickle charger is degrading the GFCI, giving electricians evidence to recommend dedicated circuits. Integrates with a clamp meter and sends results to the customer's phone.

Key Features

Plug-in GFCI tester with EV load simulation
Waveform analysis to detect harmonics causing GFCI wear
Report generation showing GFCI degradation evidence
Dedicated circuit ROI calculator for customer upsell

Target Users: Residential electricians and apprentices troubleshooting EV charging-related GFCI issues in North America, working for service companies with 1–10 trucks.

Revenue Model: $199 one-time hardware cost plus $9.99/mo subscription for advanced analytics and report customization.
