Why do I have to test my sockets?

The grounding products will only work if the socket you are using is earthed, so it is important to know that the wall socket, adapter or extension lead you want to use is earthed. Legally properties in the US have to be earthed, however if you would still like to check for peace of mind you can do this with a Socket Tester. Not all countries have a legal requirement for properties to be earthed so if you are using your grounding products abroad we always recommend taking a socket tester and earthed travel adapter with you to test the socket you want to use.
