Ecm Industries Llc GFI-3501 Ground Fault Outlet Tester

Product Description

The ECM INDUSTRIES LLC GFI-3501 is a ground fault indicator outlet tester designed to verify proper wiring and GFCI function at standard 120-volt residential and commercial outlets. The unit checks for seven common wiring errors using color-coded neon lamps that give an immediate visual indication of wiring status. A dedicated GFCI trip button allows the technician to confirm that downstream GFCI protection is wired correctly and will trip as intended. This tester is a compact, plug-in diagnostic tool used by licensed electricians and qualified electrical inspectors during rough-in verification, final inspection, and service calls.

The GFI-3501 is suited for use on standard 3-prong grounded outlets in residential dwellings, light commercial spaces, and any installation where GFCI protection is required by the National Electrical Code. It is particularly useful during new construction walk-throughs, after panel upgrades, and when troubleshooting nuisance trips or reported shock hazards. The color-coded lamp display lets the technician read wiring status at a glance without additional test leads or meters.

Installation Notes

This tester is a diagnostic instrument, not an installed component. Electricians should ensure the circuit breaker is in the on position before plugging in the tester to obtain a valid reading. Do not use on circuits with known damage or exposed conductors. Follow all applicable NEC guidelines when evaluating and correcting identified wiring faults before returning a circuit to service.
