How TripTrace Works
The diagnostic step is built around the same six fault categories electricians actually troubleshoot in the field — moisture, appliance leakage, device aging, wiring faults, overload, and HF nuisance tripping — rather than a generic 'check your outlet' checklist.
Why a checkbox diagnostic beats a generic troubleshooting article
Most troubleshooting guides ask you to read through every possible cause in order. TripTrace instead asks about your specific symptoms up front — checkboxes for things like 'trips outdoors or in rain,' 'only trips with one specific appliance plugged in,' or 'breaker also trips' — and weights each answer against the categories electricians actually use to triage a GFI complaint.
What the GFI Health Score actually measures
The score isn't a certification or a substitute for inspection — it's a structured way to see, at a glance, which fault category your symptoms point toward most strongly, and whether any of your answers should override everything else and send you straight to a licensed electrician (see our companion article on what the score means).
Why the cost estimator uses ranges, not a single number
Real 2026 installed-cost data spans a wide range — driven mainly by region and whether it's a simple swap or new wiring — so TripTrace gives you a realistic range built from published labor-rate benchmarks rather than a falsely precise single figure.
