The Kewtech KEWPROVE3 is essential for proving circuits are dead before commencing work. The high output will drive low impedance testers such as traditional test lamps as well as modern two pole testers. The one to have to be confident that it will work with your tester. It even steps down through the voltage stages to prove each stage as well. It includes batteries, instruction manual and certificate of conformity. KEWPROVE3 proving unit with up to 690V AC/DC output then steps down to 50V proving each level. · · · An essential part of safe isolation kit · · Works with any 2 pole tester

A mains socket tester with loop check, mains polarity and RCD test. It includes a standard socket test (checks the wiring configuration at the socket), a loop test (the standard socket test checks the presence of the earth connection, the 107, more importantly, also checks the quality), a mains polarity (check on the correct polarity coming into the building) and a 30mA RCD check. · · · A standard socket tester does not check for the quality of the earth connection · · A standard socket tester cannot detect a neutral live reverse at the incoming supply · · Checks correct socket outlet wiring · · Checks the quality of the earthing that is essential for safe installations · · Checks for the polarity of the mains supply · · Checks RCDs with measured current · · Bright LEDs · · Easy to use – anything other than green needs checking out · · For front line personnel
