MX AC Line Fault Detector Plug Tester for UK Sockets Auto Wire Connection Checker 3 Way LED Indicator Live Neutral Earth Fault Detector 13A UK Outlet Tester Plug-in Home Wiring Inspector MX-1177 UK
The MX-1177 UK Socket Tester is a compact plug-in electrical inspection tool for preliminary checking of compatible UK 13A power outlets. Its three LED indicators provide a quick visual reference for basic live, neutral and earth wiring conditions, helping users identify indications that may need further investigation. The portable design makes it suitable for homeowners, electricians, maintenance technicians, landlords, property managers and DIY users carrying out routine socket inspections.
Quick LED Fault Indication
Simply connect the tester to a compatible outlet and observe the illuminated LED pattern. Compare the displayed combination with the supplied interpretation guide to obtain an initial indication of the socket’s wiring arrangement. This AC line fault detector can assist with basic troubleshooting, property inspections, maintenance work and preliminary checks following electrical installation or repair.
The unit is designed as a screening accessory rather than a complete electrical safety instrument. A normal indication does not establish that an electrical installation is completely safe, while an unexpected result should be investigated using appropriate professional test equipment.
UK 13A Socket Compatibility
The tester uses a compatible UK plug format and is intended for suitable 13A UK electrical outlets commonly found in homes and commercial premises. Its compact construction is convenient for checking sockets in houses, offices, shops, workshops, rental properties and other appropriate indoor locations.
Electricians and maintenance personnel can easily carry this lightweight plug-in socket checker in a toolbox or service bag for convenient access during routine inspection work.
Durable and Portable Construction
The MX-1177 features a virgin plastic housing with a scratch-resistant finish for practical everyday handling. Solid brass plug pins with copper and nickel plating provide a robust connection design, while the glass-epoxy PCB supports the internal indicator circuitry.
Its compact size allows easy transportation between rooms, properties and service locations without adding unnecessary bulk to an electrical maintenance kit.
Simple Plug-In Operation
Before testing, ensure the outlet is suitable and follow the manufacturer’s instructions. Insert the unit into the compatible socket, observe the three LED indicators and compare the resulting pattern with the supplied guide.
The product is intended for indoor use in dry conditions. It should not be used as the sole method for confirming electrical safety, earth quality, insulation condition or regulatory compliance. Any suspected wiring fault or unusual indication should be assessed by a qualified electrician using suitable professional testing equipment.
