Earth Potential Socket Tester for UK 13amp 240v Power Socket – Checks Live, Neutral and Earth Connections and Polarity with Automatic Status Display – Includes an RCD Breaker Tester

Absolutely vital if you do electrical work on yr wall plugs. Just plug this unit into your plug pint on yr home circuit and it will test the complete supply to that socket. The light sequence will tell you if there are any problems. Good tip is to use this before you start on any work and then switch off the supply to do any work. Once work is completed turn on supply and test once again.

Already used this to make sure that my extension cable was working properly. It's nice to be able to plug something in that shows that the circuit is working properly, and that nothing has tripped off. My EV Charger was not lit up, so thought something was wrong, plugging this in instead showed that the extension cable is working, so I tried plugging in the charger again, and it fired up as it should. Guess I was doing something wrong, but no matter, it's all working now. Good to be able to figure that out with the minimum of hassle.

Arrived on time. Item as described and works well.

Worked a treat

Arrived sensibly packaged in a small recyclable cardboard box, and is exactly as advertised. Very easy to use and to read. Valuable tool to make sure I didn't fry myself or burn the house down when swapping out an old plug socket.

Since I’m an adequate diy’er I wanted something to help me make sure the wiring was correct and I wasn’t poking around in a dangerous wayThis is just plug and readInformative

Gives peace of mind to know that all sockets are safely in use.

Very good product
