GFCI TEST PROCESS
1. Press and hold GFCI button.
2. While still holding the GFCI button, insert INSP-3 plug into power socket, and then release the GFCI button.
3. Initial test values can now be viewed on the LCD screen.
4. Finally, press and hold the GFCI button once more to intentionally trip the GFCI function on the socket.
From the Manufacturer
Amprobe INSP-3 Wiring Inspector Circuit Tester
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).
- Rugged circuit tester designed to test whether a building’s wiring is in compliance with electrical code in seconds, especially voltage drop under load.
- Large display shows all relevant test data, no scrolling or switching screens needed
- Clearly indicates fault conditions with flashing values (incorrect wiring, voltage drop test failure or improper grounding)
- Test without tripping circuit breakers or blowing fuses with user selectable 10, 15 and 20 amp loads
- Check grounding for safety and ability to support sensitive electronic equipment
Important Notice: Using with GFCI/AFCI Protected Circuits
To avoid tripping the GFCI (ground fault circuit interruption) or AFCI (arc fault circuit interruption) protection, Press either the GFCI or AFCI button before you plug the unit into the outlet. To trip the breaker, plug unit into the wall without pressing the GFCI or AFCI button, the unit will test the GFCI/AFCI system by tripping the breaker.
For any technical support questions, please refer to the user’s manual or call 1-877-AMPROBE.

The array of what it tells you is impressive:
* True root mean square voltage
* Frequency (60Hz unless something is very bad)
* Voltage drop at 10/15/20Amp load for each of the hot and neutral wires (without actually putting that load on the wire and tripping your breaker)
* Loaded voltage (this and the voltage drop are ways of expressing the same thing)
* Ground Impedence
* GFCI/AFCI fault voltage
* Voltage difference between ground and neutral (common mode)
* If the breaker didn't exist what the wiring would limit a hot/neutral short current to
* If the breaker didn't exist what the wiring would limit a hot/ground short current to
The tool also flashes when any of these are out of spec. A few of my outlets had higher than spec voltage drops. These are worth following up on. Often it can be a bad splice at a wire juction, a bad connection to the outet, an undersized wire, or a bad outlet itself. At a minimum these are throwing away money when you use electric appliances in those outlets, but more concerning is these kinds of bad junctions can heat up and potentially cause fires.
Many people seem confused as to the operation of the device. The manual is written in real English, but does leave something to be desired. Below are my supplementary instructions:
1) If testing a normal non-GFCI/AFCI outlet do not power on the device, just plug it in.Read more ›
They are replacing it, but after almost a month, I still don't have my replacement. 8 days ago, I got what I though was my replacement, but it turned out they shipped me the wrong product. Now I'm still waiting. I would rank their customer service as low. They should have over nighted it to me after the shipping error.
Would not buy again. Will not recommend to other inspectors.
When I get the house rewired with GFCI outlets (and other grounded outlets), I will be able to test those aspects of the wiring as well.
The manual is printed is the tiniest possible type. I went to the Amprobe website and printed it out.
Two minor oddities. The included zipper case only has room for the cable and manual, not the instrument. The small screw on the battery door needs a plastic retainer washer to stop it from falling off the door.
In a quick walk around of my medium-sized 2-story 1989-built home I found all kinds of issues (indicated by blinking measured values), where several plugs measured 10-26% drop at 15 amp load as well as a few shorted grounds (neutral to earth). The majority were 3-5% drop, which is within NEC recommended range. All of the GFCI circuits tripped at 6mA so I couldn't test the 30mA GFCI-test feature. Now I need to decide what to do with the 20%-drop circuits... that's pretty large, and potentially could cause trouble.
I primarily purchased this to verify new 120vac wiring installed in an out-building that will be running lots of motors and where I don't want excessive voltage drop. Further, I'm using power strips and extension cords and this easily tests those as well. I'd like to think all county electrical inspectors use something like this before giving their Final Approval... wouldn't take long to do the whole house.
Build quality looks good. Case is rubberized and has a good grip (similar feel to Fluke). Red color makes case easy to spot. Back-lit screen is easy to read and text is large enough I don't need my reading glasses. Battery case doesn't show polarity, but rather you need to look at size of connector slots and match up to battery posts. No issues putting tester and plug-wire into the zip-case if I put the tester *head-down*... fits perfectly.
I found operation to be intuitive after reading some of the other reviews:
* For regular circuits just plug it in and wait a few seconds for 15A results.Read more ›
