Sperry Stop Shock II GFCI Analyzer

The Sperry Stop Shock II is a receptacle tester designed to analyse GFCI outlets at 125VAC. It detects low resistance conditions that standard testers may miss. Electricians and maintenance technicians use it to verify outlet wiring and ground fault protection quickly.

Installation requires plugging into a live outlet

Insert the tester directly into the receptacle; the LED indicators display wiring status immediately. No batteries or separate power source are needed for operation. Users must ensure the circuit is energised before testing, otherwise the LEDs will not illuminate and no reading is produced.

Sustained use shows consistent LED response

The unit performs repeated GFCI trip tests without overheating during a typical inspection session. Continuous plugging and unplugging across multiple outlets does not degrade the indicator accuracy. It is not suited for permanent installation or high voltage systems beyond the rated 125VAC.

Questions about this item

How can I confirm the Stop Shock II GFCI tester is working correctly after plugging it into a 125VAC receptacle?

The unit displays LED indicators that show wiring status and GFCI trip function; a correct wiring pattern lights the expected LEDs and pressing the GFCI button should trip a protected outlet.

What comes in the box with the Sperry Instruments Stop Shock II analyzer, and do I need any extra accessories?

The package includes the receptacle tester itself; no additional leads, batteries or adapters are required for standard 125VAC outlet testing.

Which version of the Stop Shock II should I choose for detecting low-resistance faults on a 125VAC circuit?

The listed model is a single 125VAC GFCI receptacle tester with low-resistance detection; there are no alternative voltage or capacity versions offered for this product.
