Fluke RCD Socket Tester with Beeper, 230V

The Fluke ST240+/UK RCD Socket Tester is a professional-grade diagnostic tool designed for electricians and DIY enthusiasts to quickly and safely verify the wiring integrity of standard UK power outlets. With its clear beeper alerts and bright LED indicators, it provides instant feedback on whether each wire—live, neutral, and earth—is correctly connected to the building's electrical system, giving you confidence before proceeding with any electrical work.

This compact tester can identify several common and potentially dangerous wiring faults, including reversed live and neutral connections, missing earth, and earth faults. It performs a simple one-button RCD (Residual Current Device) test, a crucial safety check for circuits protected by these life-saving devices. The unit features a fast visual identification system for all six key wiring conditions, utilising one red and two green LEDs in conjunction with an easy-to-read chart.

Rated for CAT II 300V applications, the tester is built to safely handle typical domestic and commercial electrical environments. It operates at a standard UK mains voltage of 230V AC (+/-10%) with a low 4mA current and typical power consumption of just 0.92W. Housed in a robust casing, it incorporates a standard UK Type G plug, making it ready for immediate use in the United Kingdom, Ireland, Cyprus, Malta, Saudi Arabia, and other regions using this plug standard.
