    OK I was an auto electrician back in the 70's and 80's so under stand a lot about batteries, however at that time the sealed for life battery was rather new, and you may have had a VRLA in a fire alarm, but not in a vehicle, the AGM battery was unheard of. So did have stage battery chargers for...

    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?

    Neutral to earth voltage

    Favour for a mate has turned into a nightmare. Really appreciate any comments on the below! Was asked to look at some sockets which have apparently been "sparking"....... 17th edition board. 100amp/30ma RCD as main switch and only additional protection for 11 circuits. Unsure if that conforms...
