00:00So you wanna know exactly how much power your fridge, your AC unit, or that mystery breaker
00:04in the garage is actually pulling without cutting a single wire? That's where non-invasive AC
00:10current sensors come in. You just clip them around a live conductor and you're reading amps.
00:16I've spent the last few weeks digging through the listings, comparing specs and real buyer
00:20feedback, and I've pulled together the top 5 non-invasive AC current sensor modules with the
00:25best deals right now. Let's get into it. Kicking things off is the SCT-013 split-core
00:32current transformer, and this one's the crowd favorite for a reason. You can pick your range,
00:3710, 20, 30, 50, or a full 100 amps, so whether you're monitoring a single appliance or a whole
00:42subpanel, there's a version that fits. The clamp snaps open and closed with one hand,
00:48and it's got a perfect 5-star rating across nearly 4,900 sold. At $3.30, honestly, it's cheap enough
00:56to buy 3 and sensor your entire house. Next up is the SCT-013-020, and this is the one
01:03I'd point you
01:04to if you're building something you actually care about. It's a dedicated 20-amp input model, which
01:09means you're getting better resolution on smaller loads instead of stretching a 100-amp sensor across
01:14a tiny reading. It's purpose-built for DIY energy monitoring projects, think Arduino, ESP32,
01:21home assistant dashboards. At $77.96 it's the premium pick here, but the accuracy on low current
01:28circuits is where it earns that price. Third on the list is this high-quality SCT-013 variant,
01:34and what stands out is the sheer number of options. 5, 10, 15, 20, 30, 50, 60 amps,
01:41plus the classic SCT-013-000. That 5-amp version is genuinely hard to find elsewhere,
01:48and it's perfect for monitoring individual outlets or small motors where a bigger sensor
01:53would just give you noise. 2455, 5-star rating, over 4,700 sold. If you need a specific range,
02:02this is your listing. Coming in at number 4 is the SCT-013-000 open-close transformer module,
02:09and this one's all about the spec sheet. You're looking at a 1-volt output, 50 milliamp rating,
02:15and 1% accuracy, that last number matters, because a lot of cheap clamps drift way worse than that.
02:21It covers everything from 10 amps up to 100. And the price? $3.14. That is the best accuracy
02:31per dollar on this entire list, full stop. Rounding out the top 5 is another SCT-013-000,
02:39available in 30, 50, and 100-amp versions, aimed squarely at the heavier stuff, mains monitoring,
02:45EV chargers, workshop equipment. The split-core housing feels solid, the clamp closes with a
02:50nice positive click, and buyers consistently mention it holds calibration over time.
02:55It's sitting at 4799 with a 4.9 rating and over 4,500 sold. If you're wiring up a permanent
03:03whole-home energy monitor, this is a safe bet. That's the top 5. All the links are down in the
