I use OutletIQ on every renovation project now. The digital readout beats the old flicker-light testers I used to squint at, and it already caught reversed hot/neutral wiring on two different jobs.

Bright Digital Display

Based On Real and Honest Experiences
I bought OutletIQ after my electrician left and it already paid for itself. It caught an open ground in my kitchen outlet before I plugged in a new fridge, exactly the kind of miswire I would never have noticed myself.
Emily R.· Verified Buyer
Honestly figured this was another gimmicky gadget from a brand I'd never heard of, until it caught reversed polarity in my guest room the first time I used it. OutletIQ is solid and well-made, and I highly recommend it to anyone doing their own wiring.

Frequently Asked Questions
+164 expertsreviewed itOutletIQ shows a plain status for each check, like correct wiring, open ground, or reversed polarity, so you read the result directly instead of matching blinking lights to a paper chart.
Press OutletIQ's dedicated test button to simulate a leakage event. If your GFCI or RCD outlet is working correctly, it will trip and cut power immediately, confirming your protection is active.
OutletIQ checks the actual electrical path, not just whether a wire is physically attached. A loose connection or bad splice further down the line can look fine but still break the circuit, and OutletIQ will flag it correctly.
OutletIQ is built for quick diagnostic checks rather than continuous use. Unplug it once your test is complete to keep it performing accurately for years.
OutletIQ accurately reads AC voltage from 48V to 250V, making it a great fit for standard homes and most light commercial spaces.
Absolutely. OutletIQ detects reversed Live and Neutral wiring as well as Live and Ground reversals, helping you avoid appliance damage from incorrect polarity.
Cheaper testers often use blinking lights that are easy to misread and plastic bodies that crack within months. OutletIQ gives you a plain, direct reading and rugged construction, so you are not trading accuracy or durability to save a few dollars.
If pressing the RCD button produces no response, your breaker itself may be faulty. We recommend having a licensed electrician inspect your wiring right away.
