Product Description

The Amprobe INSP-3, wiring inspector is a rugged tester designed to verify building wiring compliance to electrical code, especially voltage drop under load. Identify issues with splices, connections and conductor quality, crucial to safety and performance of the electrical system.

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).

Product Features

  • 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.

If you are an electrician, are buying a home with suspected electrical problems, own a home with suspected electrical problems, or are doing some electrical work yourself I highly recommend this tool.

The array of what it tells you is impressive:
* True root mean square voltage
* Frequency (60Hz unless something is very bad)
* Polarity
* 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.

Hello everybody,

I've used this tool to check the electrical system in my house.

I admit I was a little scared about this tool because i don't know much about electricity but guess what? even though the user manual leaves some room for improvement, you can see videos in facebook explaining the functions.

The tool let me found some faulty circuit breakers that for some reason supported more consumption than they were supposed to. On the other hand, I found some weird things about the ground that normal 3 leds tester were unable to find. The thing was, the resistance was too high because of humidity some ground contacts at the outlets were corroded.

I found that about 30% of my house outlets were faulty and had to repair some terminals. This sounds alarming and it is, were I live there's no such thing as home code inspection but now thank to this very useful tool I rest assured my house is a safer place for my family and since my family means utterly everything to me, I can tell you I've learned some electrical things, My house works better, and I feel better too.

I greatly recommend this tool to every concerned father and husband with some DIY skills, not that difficult to understand but gives you peace of mind. If you're not DIY inclined, just make somebody with this or similar tool check your house because beyond local electrical codes, your house is where your beloved ones lives... and that's enough reason to be sure everything is working properly.

You can check circuit breakers, ground health, cabling and the lot... it's even funny to use.

Hope this helps!!!

JP

If you are reading this review because you're struggling to get this tester to work properly, let me offer this advice: Don't use the POWER button. If you turn it on with the POWER button you'll likely be frustrated.

The INSP-3 is a professional hand-held tester that checks GFCI, AFCI, Polarity, Voltage Drop, True RMS voltage and Ground Impedance on 120 volt single phase circuits. It does not check the condition of the insulation.

It has a standard NEMA 5-15 three-prong plug you insert into the receptacle to be tested. If you want to test a circuit with old-fashioned 2 prong receptacles, you'll need to supply your own adapter.

The instructions included with this tool are rather brief. I struggled for 10 minutes trying to test for voltage drop on a GFCI circuit before I figured out that I should NOT turn the tester ON before using it! To be clear, the instructions don't actually say "Turn the tester on". I just assumed that pressing the POWER button was the first step ..... my mistake!

After that, the tester worked great. I went all through the house testing receptacles and found the living room circuit, which is the farthest from the service panel, has excessive voltage drop (11% @ 20 amps). That explains why my chop saw functioned so poorly that time I used it on the front porch and powered it with an extension cord from the living room.

GFCI testing reports the milliamps required to trip the device as well as the time (in tenths of a second) that elapsed before it tripped. This tester found one GFCI in my home that consistently tripped during the 15 amp load test, never allowing me to proceed to the ground fault test. That GFCI device has never given me trouble, so I'm impressed that the tester identified the problem.
