Wavecom TNT RCD Review (2025)
The Pros – Built-in RCD testing thanks to internal isolation transformer. Battery powered with lithium-ion battery does up to 3000 tests per charge. Very easy-to-use.
The Cons – No memory storage. No PC connectivity or data export. Very basic protective case. Feels a bit dated compared to newer models.
The Bottom Line – The Wavecom TNT RCD is a step up from the TNT EL, thanks to its RCD testing capabilities. It’s battery powered and user-friendly, making it decent for beginners who want to stay compliant. But if you're after modern features like data logging, connectivity, or long-term scalability, this one will feel limited.
Key Features of the TNT RCD
Released as part of Wavecom’s Generation 5 series, the TNT RCD appliance tester is designed for tradies or small businesses wanting to meet AS/NZS 3760 requirements without diving into higher-end setups.
The main advantage over cheaper models like the TNT EL (considered one level below) is that this unit can test both fixed and portable RCDs thanks to the built-in isolation transformer – a feature normally found in much more expensive models.
And even though it's a few years old now, the TNT RCD still holds up as a practical option for light-to-moderate testing.
Battery Powered with Long Run Time
The TNT RCD is powered by a rechargeable lithium-ion battery, giving you around 3,000 tests per charge. That makes it ideal for mobile jobs or sites without reliable mains access.
It’s not the smallest PAT Tester on the market, but it’s comfortable to carry and comes with a soft carry bag for portability.
One-Button Testing Made Simple
Everything is controlled via just a couple of buttons for extra simplicity:
- Press F1 for Class I tests
- Press F2 for Class II tests
Each electrical test runs automatically, and the screen shows the test result in real numbers, along with a clear PASS/FAIL result. There’s no scrolling or setup menus – just press and go.
How it Performs in the Field
The TNT RCD is a solid entry-level choice for people who want something that works out of the box with minimal learning curve. It’s a popular option for any first-time test and taggers that need to have RCD capability, or people testing in low-volume in offices or small businesses.
That said, the lack of data storage means you’ll be writing down results manually, which gets old quickly if you're testing and tagging regularly.
And while it’s portable, the included pouch doesn’t offer much protection. If you're rough on your gear or working on site, a more rugged case would help.
Drawbacks to Consider
- It feels quite flimsy to hold, even still taking into account its price
- No PC connectivity - can’t export results
- Not scalable - no path to add features later
- Some newer appliance testers offer better value
Is It Worth It?
If you need a basic portable appliance tester plus RCD functionality and don’t want to break the bank, the TNT RCD does the job. It's priced well under $1,000 and will cover you for most everyday testing and tagging needs.
But if you think you’ll want data logging, or report generation down the track - you're probably better off skipping this one and looking at either the Metrel DeltaPAT 3309 BT or Kyoristu 6205.
