The Martindale socket and earth loop tester, RCD tester detect 28 faulty conditions and voltage level indication. It has a nominal operating voltage rating of 230V and current rating of 32A. This is also used for trip testing 30mA RCDs. It shows how safe the earth wiring, checks for polarity swap at the incoming supply.
Features and Benefits
• Quick and easy testing of polarity, loop impedance and RCDs • Red/green LED indication for fault • Buzzer indication when electrical fault occurs • Non-trip earth loop impedance test • Incoming electrical supply polarity swap test • Tough sculpted design for easy removal • Earth loop threshold accuracy: ±(10% + 0.3:) • Power consumption: <2.5W • Operating temperature ranges between -10°C and 40°C
