The tester uses three brass pins that plug directly into the socket under test, drawing mains power to illuminate a series of LED indicators that show the status of live, neutral and earth connections.\u003c\/p\u003e\n\u003cp\u003eIntended for electricians, facilities maintenance teams and DIY installers working on domestic or light commercial electrical work, the TE3 checks six common wiring faults: outlet wired correctly, missing earth, live\/neutral reverse, missing neutral, live\/earth reverse, and wiring fault combinations. The LED pattern displayed on the blue polycarbonate face corresponds to a fault diagnosis chart printed on the unit, allowing immediate identification of incorrect wiring without needing a separate reference sheet.\u003c\/p\u003e\n\u003cp\u003eThe compact 66mm x 66mm x 48mm polycarbonate body fits easily into a tool pouch or electrician's kit and weighs approximately 60g. The tester operates at 230V 50Hz mains voltage and carries IP20 ingress protection, meaning it is suitable for dry indoor use only and must not be used in damp locations, bathrooms or outdoor sockets. The unit is certified to EN 61326 and EN 61000 electromagnetic compatibility standards.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e66 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e66 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e48 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e26 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBlue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_1059597_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat faults does the TE3 detect?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe tester checks for six fault conditions: correct wiring, missing earth, live\/neutral reverse, missing neutral, live\/earth reverse, and wiring fault.
