What the Tester Does

The Reliance THP102P checks 120V AC receptacles at 60 Hz for correct wiring and GFCI function. It plugs into a standard 5-15P outlet and uses indicator lights to show wiring status. The unit includes a 40 in. power cord and carries cULus certification with a one-year manufacturer warranty.

Who Should Use It

Electricians, inspectors and DIYers verifying standard household outlets will find it straightforward. It does not suit users who need a digital readout, data logging or the ability to test circuits outside the 120V 60 Hz range. Buyers requiring a CAT-rated safety category should choose a different instrument.

Deciding Specification

The tester operates only on 120V AC at 60 Hz with a NEMA 5-15P plug. If the installation uses a different voltage, frequency or receptacle style, this tool cannot perform the check.

Questions about this item

The unit includes the receptacle tester with an integrated 40 in. power cord and NEMA 5-15P plug; no batteries or additional accessories are required for basic operation.

Which version should I select for standard North American 120V household receptacles?

The THP102P is rated for 120V AC at 60 Hz with a NEMA 5-15P configuration, matching typical residential outlets; choose this model for that application.
