Product Description

Rugged circuit tester designed to verify building wiring compliance to electrical code
Test without tripping circuit breakers or blowing fuses
Large display shows all relevant test data, no scrolling or switching screens needed
Save Time and Money

The INSP-3 Wiring Inspector Tester is a rugged tester designed to verify building wiring compliance to electrical code, especially voltage under load. Testing electrical lines under load provides information on line conditions, which can diagnose issues such as high voltage drop and high ground impedance. Voltage drop relates not only to safety, but also to the function and reliability of electrical systems. Checking voltage drop under load assures that lines are in good condition, safe and will hold up for years of efficient operation. The INSP-3 saves time and money by eliminating the guess work associated with remodeling, new construction and maintaining wiring systems.

Packed with Features

The INSP-3 applies a constant 10, 15, or 20 AMP simulation current regardless of the voltage on the line tested. The unit tests ground fault circuit interrupter (GFCI) and arc-fault circuit interrupter (AFCI) protected circuits and non-protected circuits. The tester can be used on 95 to 140 VAC. Incorrect wiring or voltage test failure is clearly indicated by flashing values on the screen. The LCD displays all relevant test data (voltage, voltage drop, hot and neutral voltage drop, voltage with load, ground impedance) on a single large display to save the operator time. The device will not trip circuit breakers or blow fuses during testing.

A Wide-Range of Applications

The INSP-3 verifies that wiring meets electrical code recommendations for voltage drop under load. It will show how much specific drop is on the hot and neutral conductor. This is a great way to check splices, connections and conductor quality, which is crucial to safety and performance of computers and sensitive electrical equipment. Find faulty wiring that needs repair without removing outlet cover plates or panel covers, including faulty splices and connections, incorrect wiring, undersized wiring, faulty or incorrectly wired AFCIs/GFCIs, incorrect line voltage and poor ground quality. This is the tool of choice for hospitals, offices, homes, server data banks, RV parks and anywhere where proper receptacle wiring is critical for safety and performance. The INSP-3 is often used for home inspections and post wiring installation inspections to verify compliance with National Electrical Code (NEC).
