## Overview

The Amprobe Insp-3 Wiring Inspector is a professional-grade digital circuit tester designed for electricians and technicians to verify building wiring compliance. It simulates constant loads of 10, 15, or 20 amps, measures voltage and ground impedance, and tests GFCI/AFCI circuits. Safety certified to IEC 61010-1 Category II standards, it delivers precise, efficiency-focused diagnostics to ensure your electrical systems meet code and operate safely.

## Description

Amprobe products range from an extensive line of clamp meters and digital multimeters to industry-specific tools for residential/commercial electricians, HVAC/R technicians, utilities and industrial maintenance professionals. All Amprobe tools undergo rigorous testing to ensure full compliance with the latest IEC and CE safety regulations in Fluke Safety labs for quality and safety you can trust.

Review: Internal fault repair. - This tool is effective until the "internal failure" you may have read about in other reviews. Unfortunately the cause of the failure is a blown fuse. This fuse is SMT. If you are handy you can install a different type and get your unit back up. You will need to order a 6.3 Ah axial fuse. See photo for location.
Review: The 2nd and 3rd have had internal faults which have rendered them useless. It was a useful tool when it worked - I have purchased three of these. The first one I lost. The 2nd and 3rd have had internal faults which have rendered them useless. It was a useful tool when it worked, but I am not satisfied with its durability.

I have purchased three of these. The first one I lost. The 2nd and 3rd have had internal faults which have rendered them useless. It was a useful tool when it worked, but I am not satisfied with its durability.

### ⭐⭐⭐⭐ Easy to use, fast results (seconds), and lots of useful information on branch circuit health
*by J***W on March 12, 2015*

I wish I had this years ago. Measures several values in seconds on hot, neutral, and ground wires that tell you a lot about the health of a single-phase 120vac branch circuit. Pretty slick. 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. Toggle between the two data screens with the yellow Power/Select button. * Initial test is for 15A load. You can press 10 or 20A load buttons after 15A results post and the screen will refresh. * For GFCI or AFCI circuits you need to press one of those buttons *before* plugging in, and follow screen instructions. It will show load results first and then test the other features. I did find that even after pressing the GFCI button the GFCI breaker/outlet would occasionally trip which was a nuisance; it might be I was moving from one outlet to another without resetting the unit (using power button.) It may be worthwhile going to the Amprobe website... they sometimes offer reward gifts based on dollars spent (just like Fluke). In my case my Amazon purchase of this product qualified for other free Amprobe goodies. There's also a product registration page there. UPDATE 9/16/15: I reduced the rating a point due to ongoing problems assessing some GFCI breakers where (as mentioned above) the breaker will trip even when the tester is in the right mode. In some cases I've had to reset the breaker up to 10 times before I got test results. If the outlets being tested are a long distance from the breakers and there are no helpers around to reset the breaker this can be a real time killer.
