TeestaSok Socket Tester Is Here To Help You Verify Every Circuit, Detect Every Fault, And Sign Off Every Installation With Total Confidence.

Need To Quickly Verify Whether A Socket Is Correctly Wired Before Connecting Equipment Or Signing Off An Installation?

TeestaSok Socket Tester identifies seven distinct wiring fault conditions — correct wiring, open ground, open neutral, open live, live/ground reverse, live/neutral reverse, and live/ground reverse with missing ground — the moment you plug it into a socket. The clear LED indicator pattern and backlit LCD display present the circuit status instantly, eliminating the need for complex multi-meter setups and allowing rapid socket verification across an entire installation in a fraction of the usual time.

Worried About Whether The RCD Or GFCI Protection On A Circuit Is Actually Functioning As It Should?

TeestaSok performs a direct RCD test with a single one-second button press, triggering a test current above 30mA (or above 5mA for GFCI) to verify whether the protective device trips as required. If the MCB trips, the RCD is confirmed operational — if not, the circuit requires professional attention. This built-in RCD testing capability makes TeestaSok an essential socket tester for property safety inspections, rental compliance checks, and post-installation verification.

Looking For A Socket Tester That Covers More Than Just Basic Fault Detection?

TeestaSok's backlit LCD display also shows live AC voltage (90–250V), neutral-to-earth (N-E) voltage, and RCD current readings in real time, giving you a comprehensive picture of the circuit's electrical condition beyond a simple pass/fail result. Available in US, EU, and UK plug formats and rated to CAT II 300V with full CE certification to EN61010 and EN61326 safety standards, TeestaSok is a genuinely professional-grade socket tester suitable for domestic, commercial, and light industrial electrical testing environments.

Identify Wiring Faults, Verify RCD Protection, And Check Polarity In Seconds With A Socket Tester Built Around Professional-Grade Diagnostics.

Beyond its core fault detection and RCD testing capabilities, TeestaSok Socket Tester includes a range of practical design features that make it a reliable, easy-to-use, and fully certified tool for everyday electrical safety work.

• Dual-Colour Backlit LCD Display for clear reading in low-light environments
• N-E Neutral-To-Earth Voltage Measurement for complete circuit assessment
• CAT II 300V Safety Rated to EN61010 and EN61326 international standards
• Compact Plug-In Design requires no batteries, probes, or setup

SEVEN-CONDITION WIRING FAULT DETECTION SYSTEM

TeestaSok identifies seven wiring conditions — from correctly wired to open ground, open neutral, open live, and both reverse polarity configurations — instantly upon plug-in, providing a complete circuit diagnosis without additional test equipment.

RCD/GFCI PROTECTION FUNCTION TESTING

A single one-second press initiates an RCD test above 30mA (or 5mA for GFCI circuits), confirming whether residual current protection is active and operational — an essential safety check for property inspections, rental compliance, and post-installation sign-off.

LIVE AC VOLTAGE AND N-E VOLTAGE DISPLAY

The backlit LCD shows real-time AC voltage from 90–250V and neutral-to-earth voltage simultaneously, giving you detailed electrical data beyond basic wiring status for a complete and professional socket assessment.

UNIVERSAL US, EU, AND UK PLUG COMPATIBILITY

TeestaSok is available in US (Type B), EU (Type D), and UK (Type E) plug formats, making it a genuinely international socket tester suitable for electrical professionals working across multiple regions and installation standards.

CE-CERTIFIED PROFESSIONAL SAFETY STANDARDS

Full CE certification to EN61010-1, EN61010-2-030, and EN61326-1 at CAT II 300V ensures TeestaSok meets the rigorous international safety requirements demanded for professional electrical testing instruments.

INSTANT PLUG-IN OPERATION — NO SETUP REQUIRED

TeestaSok requires no batteries, probes, leads, or configuration — simply plug it into any socket within its rated voltage range and read the result immediately, making it the fastest and most practical socket tester for high-volume installation checks.

Frequently Asked Questions

Q1: What wiring fault conditions can TeestaSok Socket Tester detect?

TeestaSok detects seven conditions: correct wiring, open ground (missing ground), open neutral (missing neutral), open live (missing live), live/ground reverse, live/neutral reverse, and live/ground reverse with missing ground — covering the full range of common socket wiring faults.

Q2: How does the RCD test function on TeestaSok work?

Press and hold the RCD TEST button for one second to trigger a test current above 30mA (or above 5mA for GFCI). If the circuit's MCB or RCD trips, the protective device is confirmed operational. If it does not trip, the RCD requires inspection by a qualified electrician.

Q3: What voltage range does TeestaSok Socket Tester measure?

TeestaSok measures AC voltage from 90V to 250V at 45–65Hz, and displays N-E (neutral-to-earth) voltage alongside RCD current readings on the backlit LCD — providing comprehensive real-time electrical data for a complete circuit assessment.

Q4: Which plug formats is TeestaSok available in?

TeestaSok is available in three plug formats — US Type B, EU Type D (Schuko), and UK Type E — allowing you to select the version appropriate for your region's socket standard and installation environment.

Q5: Is TeestaSok suitable for professional electrical installation work?

Yes. TeestaSok holds CAT II 300V safety certification and full CE compliance to EN61010 and EN61326 international standards, making it appropriate for professional electricians, electrical contractors, safety inspectors, and facility maintenance engineers.

Q6: Does TeestaSok require batteries or any setup before use?

No. TeestaSok draws power directly from the socket being tested and requires no batteries, probes, leads, or pre-use configuration. Simply plug it in and read the wiring status result immediately from the LED indicators and LCD display.

Q7: What does a live/ground reverse fault mean and why is it dangerous?

A live/ground reverse condition means the live and ground wires are swapped at the socket. This leaves the ground conductor energised, creating a serious shock hazard for anyone touching the earthed casing of connected appliances — even when switched off.

Q8: Can TeestaSok be used for both domestic and commercial socket testing?

Yes. TeestaSok's 48–250V measurement range, seven-fault detection capability, and RCD test function make it suitable for domestic property inspections, commercial fit-outs, rental compliance checks, and light industrial socket testing across all standard installation environments.
