I didn't...

    Contactor. Proving dead . 3 phase .

    When working in a control panel. If I needed to replace a 3 phase contactor do I need to carry out a 10point check to prove dead on just the mains isolator. Or do I need to 10point check the mains isolator and then another 10point check on the contactor before removing. Many thanks

The device starts at 690 volts which is ok for my Megger 2 pole tester. My fluke clamp meter has a limit of 600 volts. The second problem...

    Recommendations for a Voltage Indicator and Proving Unit

    I’m looking to save for a Safe Isolation Kit, we done the Safe Isolation procedure in College using a Martindale Kit. But would anyone have any recommendations for a kit to buy? The Martindale was good but I’ve seen a few other manufacturers that seem to offer more features but are they worth it?
