Proving Units

Proving Units are essential safety devices designed to verify that voltage testers are functioning correctly before and after use.

They are widely used by electricians, maintenance engineers, and safety inspectors to ensure compliance with safe isolation procedures.

Use cases include confirming tester accuracy on site, meeting regulatory requirements, and reducing the risk of false readings during live-dead-live testing.

The benefits include enhanced safety, compliance with health and safety standards, and peace of mind that equipment is operating as intended.

YESSS Electrical stocks reliable proving units from leading brands such as Kewtech, Megger and TIS trusted for accuracy and durability.

Customers often search for specifications including output voltages from 50V to 690 V AC/DC, compatibility with two-pole testers, compact portable designs, and battery operation.

For safe working and regulatory compliance, choose a proving unit as part of every electrical isolation procedure.
