Socket Testers

A socket tester is a small, hand held device that is plugged into a socket to quickly confirm that an AC wall outlet is working and can provide the power that is needed to power the devise that will be plugged into it.


Socket testers are used to ensure that the wiring is the correct way round. It will detect when there is no earth but will not check if the earth is in good condition if it is there.


The lights on the front of the mains outlet tester will light up in different combinations, this will indicate if there is any type of fault.


There are different types of socket testers:

Simple testers can detect a number of different faults but they cannot indicate or measure effective the earth fault loop impedance. They are normally the same size as a 13A plug.


Advanced testers have the same normal functions that a simple tester has including reversed line and earth, or reversed line and neutral. They display the range of numerical values that the earth fault loop impedance falls.


Professional testers have the same normal functions that a simple tester has including displaying numerical value of earth loop impedance. They also be used to measure the values of earth loop impedance to certify or report on the installation that has been carried out.


Who would use a socket tester?


Electricians, maintenance personnel, DIY enthusiasts, handymen and equipment installers would general have a mains socket tester in their toolbox to check the safety of the socket and prevent shocks and accidents occurring.
