The Megger 1000-211 Box of 10 Socket Testers are designed to identify wiring faults at UK BS1363 13A 3-pin power sockets. Over 17 combinations of wiring fault can be identified including missing wires and incorrect or reversed connections. Faults are signaled by 3 bright LEDs on the front of the unit, with a simple diagnosis chart for typical errors included on the label next to the LEDs, 2 green LED’s signal a correctly wired socket, and a third red LED identifies a fault. If either green LED fails to light, or the red LED comes on, a fault is present and will require further investigation.

The MST210 can be used for initial identification of socket faults following socket replacement or re-wire work of any kind. Simple miss-wires or missing connections can be quickly identified prior to full BS7671 electrical test and inspection, so saving time during the testing and certification process. The MST210 may also be used during installation or commissioning of electrical equipment connected to 13 A sockets (such as white goods) if a wiring fault is suspected.
