I recently picked up the Klein Tools CL120VP Electrical Test Kit on Amazon (you can check it out here). It’s a game-changer for anyone doing electrical work—whether you’re a pro or just tackling some home DIY tasks. But let me be super clear upfront: electrical work can be dangerous. If you’re not experienced, it’s always safer to call a licensed electrician. That said, here’s my honest take on this kit and how it’s helped me.
What’s in the Box Klein Tools CL120VP?
This kit comes with four essential tools that cover pretty much everything I’ve needed so far:
✅ CL120 Clamp Meter
✅ RT210 GFCI Receptacle Tester
✅ NCVT-3P Non-Contact Voltage Tester
✅ ET40 Voltage Tester
✅ Test Leads, Batteries, and a Handy Pouch
The CL120 Clamp Meter
This meter is the workhorse of the kit. It measures AC current via the clamp, and AC/DC voltage, resistance, and continuity with the test leads. The auto-ranging feature is fantastic—it saves me from second-guessing the settings. Plus, the backlit LCD screen is easy to read, even when I’m working in dim areas (which happens more often than I’d like).
I’ve used the clamp to check load currents in circuits I was troubleshooting and the test leads to confirm continuity and measure voltage on outlets. It’s rated CAT III 600V, which gives me peace of mind knowing it’s designed for serious work.
RT210 GFCI Receptacle Tester
This little guy has been a lifesaver for checking outlets around the house, especially after some recent renovations. It quickly tells me if there’s an open ground, reverse polarity, or other wiring issues—and it’s super easy to interpret thanks to the chart on the front.
For anyone moving into an older home, this tester alone makes the kit worth it. But again, don’t try rewiring outlets yourself if you don’t know what you’re doing. Call a pro if you find a problem.
NCVT-3P Non-Contact Voltage Tester
I absolutely love this tool for its dual-range voltage detection (from 12V up to 1000V AC). It’s fast, reliable, and even has a built-in flashlight—huge help in dark crawl spaces or behind appliances. I used it just last week to check for live wires when I was planning to replace a light fixture. It kept me safe and saved a lot of guesswork.
ET40 Voltage Tester
The ET40 is a compact little tester that can check both AC and DC voltages at common levels. It’s great for quickly verifying battery levels or low-voltage circuits like doorbells or thermostats. It’s a bit of a “nice-to-have” in the kit because the clamp meter covers most of the same ground, but having a dedicated tool just for this makes things faster.
Final Thoughts
Overall, this kit has been a fantastic addition to my toolbox. It’s reliable, easy to use, and covers a wide range of electrical testing needs. Klein Tools is a name I trust, and this kit lives up to their reputation.
But let me emphasize this: DIY electrical work isn’t for everyone. These tools make it easier to troubleshoot and identify problems, but they don’t replace the skills and safety knowledge of a professional electrician. If you’re unsure, always hire a licensed pro.
That said, if you’re ready to tackle safe, simple tasks like checking outlets, verifying voltages, or basic circuit checks, this kit is hard to beat. Plus, it’s available at a great price on Amazon.
