CED Plug in Socket Tester (S76975F)

One of the first items that you should use before working on any socket, either to repair it or to check if it is working is a plug in tester


It goes without saying that before you work on any electric socket is to check if it is live, and no that does not include sticking your fingers inside it.


If you just plug the plug in device in to the socket it will do two obvious immediate things, the first if any of the lights come on, indicates the presence of power at the socket, and the second dependent on what lights come on, what fault is at the socket.


To a certain extent the average home user will just want to know if power is at the socket, which as explained the plug in tester will do, but always test the tester by plugging it into a known live socket before using it so that the lights on the tester work.
