The Kewtech KEWISO4 Safe Isolation Kit is a practical, regulation-compliant solution designed for UK electricians and electrical technicians who need to carry out correct safe isolation before working on electrical circuits. Built around the KT1720 two-pole voltage tester, this kit provides a reliable and battery-free method of confirming dead before work begins.
The kit includes a high-output proving unit, a universal lock-off device and a dedicated carry case, ensuring all stages of the safe isolation procedure can be followed correctly. With AC and DC voltage testing up to 400 V, the KEWISO4 is ideal for domestic, commercial and light industrial installations.
How does the KEWISO4 support everyday safe isolation?
The KT1720 tester requires no batteries and uses clear LED indicators to show voltage presence and polarity, reducing the risk of tester failure. Combined with the KEWPROVE3 proving unit and KEWLOK lock-off device, the KEWISO4 helps electricians work efficiently while maintaining full compliance with UK safe isolation best practice. The carry case allows access to the proving unit without removal, reinforcing correct procedure on site.
