Mains Power Socket Tester - 13A

It checks for a suitable and safe earth connection and verifies the correct live and neutral polarity of the mains socket.

No, this tester is specifically designed for 13A UK mains sockets.

It operates within the 200-250V range and indicates correct polarity, but it is not a voltage meter; it does not display the exact voltage reading.

It typically means the socket is not receiving power, or there is a complete break in the live circuit. Ensure the socket is switched on and properly wired.

Yes, when used correctly on appropriate sockets, it is safe. It is designed to indicate safety faults, not create them.

The tester provides a visual indication when plugged in. Generally, a correct earth is indicated by a specific light pattern (consult the product manual for exact indicator meanings if provided). If the earth indicator does not show correctly, the earth connection is not considered safe.

This tester is intended for indoor use in dry conditions. Avoid using it in wet or damp environments.

Ensure the socket is switched ON at the mains. Check that the tester is fully and correctly inserted into the socket. Verify the socket is receiving power by testing with another known working appliance or using a multimeter.

Do not use the socket. This indicates a wiring fault. Immediately disconnect the tester and consult a qualified electrician to inspect and rectify the socket wiring.

Ensure you are using a standard 13A UK socket. If the fit is still loose, the socket contacts may be worn. Do not rely on the tester's reading in this case and have the socket inspected.
