Circuit Tester Reviews

A circuit tester or outlet tester is a device or gadget which is plugged into an electrical socket to check if it is wired properly. A circuit tester basically has a single light or series of lights that show the state of the wiring in the outlet. This device is used by the technician to verify that the wiring has been installed properly in the outlet. The light attached to a circuit tester glows when it comes in contact with AC i.e. (Alternating Current) and ensures the proper working of a wired outlet.

Who Needs Circuit Tester Can?

The main reason to use a circuit tester is to ensure that electricity which runs through an outlet is actually AC. Most of our household devices run and work on AC. Using a circuit tester ensures that an electronic device only receive AC not DC i.e. ‘Direct Current’, which can cause damage to different electronic devices. DC can cause harm not just to the electronic devices but can also prove to be fatal for human beings and other living things. So a circuit tester is a very important device used to ensure that DC will not come in a wired outlet.
