EM908 Socket Polarity RCD Tester

The Faithfull EM908 is a compact socket polarity and RCD tester designed for electricians and contractors who need to verify mains socket wiring safety and RCD functionality. This essential electrical safety tester determines whether UK 240V 3-pin sockets are wired correctly, helping to identify potentially dangerous wiring faults before they cause problems. The tester uses three neon indicators to show the status of Live, Neutral and Protective Earth connections, working alongside two additional indicators to provide a comprehensive five-light diagnostic system. Used in conjunction with the supplied coding table, these indicators quickly reveal the true wiring condition of any socket. The integrated LCD display provides crucial ground error indication, alerting users to dangerous contact voltage present at the protective earth terminal. An additional RCD testing function allows electricians to verify the operation of residual current devices rated up to 30mA, with test times between 60-300ms. This dual-purpose capability makes the EM908 particularly useful for electrical installation testing, periodic inspection work, and troubleshooting socket circuits in domestic and commercial properties. Rated to CAT III 300V for safe use on distribution circuits, the lightweight 70g tester fits easily into a tool bag or pocket.
