Testing Equipment You Probably Don't Have, But You Definitely Need in Your Electrician Tool Belt!

With so many types of test equipment available for the electrician, its hard to keep track of what is out there. In this episode of Electrician U, Dustin talks about some of the testing devices that one of our sponsors, Klein Tools, has available.

First up is a simple voltage tester. No frills, but definitely worth thinking about. All it tells you is if there is voltage present. But that is the beauty of it! Less to break, less to malfunction! Small and compact, it easily fits in your pocket or tool pouch and its price is also super affordable. In addition, it does test on a range of voltages not just 120.
Klein’s ET-310 is next on our list of testers. This tool allows you to plug one end into a receptacle and with the other end (wand) you can go to the panel and scan the breakers until it audibly lets you know which one you are plugged into on the other end! Super handy and keeps you from running back and forth between panel and receptacles until you find out which one you are working on!!
Also available from Klein is a thermal imager. Unlike a standard laser type thermometer, this device also has a screen which allows you to SEE an infrared picture of what you are testing, not just get the digital readout of the temperature. This can be very useful in identifying hot spots in a circuit where there is a potential problem point or a loose joint/connection, without having to disassemble each and every device/bolt in the arrangement.
Klein's Amp Clamp type meter is next up. This tool will typically tend to have Less testing options than a Digital Multi Meter, but More than a standard voltage only tester. In addition, it has a split clamp on one end that you can clamp around a wire to see just how many amps are flowing through the circuit you are testing. They are available in different voltage and amperage ranges to suit the need of the electrician. If you are going to have one type of meter in your arsenal, make sure it is this type! They are totally invaluable!
A borescope is the next test instrument we look at. While not something that you would use every day, it is surely nice to have to allow you to look into an opening and behind something that you normally couldn’t see into. So, say for instance you wanted to see if there was an obstruction inside the wall cavity you just cut a box into, you could simply insert the camera end of the borescope into the hole and look around! Nice!!
A Megger is a tool that the average electrician probably Doesn’t have in their personal tool kit, but one that most of us have used them. These typically look much like a multi meter, but what they do is send a high voltage signal into the conductor they are clamped onto and can sense if that current is leaking out somewhere and escaping indicating a potential problem point within the conductor. A definite must use tool for the electrician.
The last tool we are looking into is a Earth Resistance Tester. This particular meter is a three-point fall of potential type, though there are four-point fall of potential types available. This tool allows you to test the immediate earth surrounding the area you are working in to see how much resistance the earth carries. An invaluable tool for service installations/problematic grounding testing.
We hope this has been helpful in showing you what types of electrical testers are out there that you can easily access and which ones to select. Continue to follow Dustin and Electrician U as we are constantly adding new content to the platform
