    EICR R1+R2 testing requirements

    What’s your thoughts on this, house testing I would say no argument against this, mains isolation & tests can be carried out. Commercial properties where isolation is not possible i certainly would not do a R1+R2 test, also knowing the EOL near impossible. Electrician’s are now deducting the Ze...

    ZS testing - dangerous?

    I have read somewhere that performing a zs test where there is exposed metalwork and people around can be dangerous? Is it something that has to be avoided? Or does it say anywhere that it must not be done? Should i be worried about carrying out Zs tests now? :/

    Hi all hope everyone’s well. Sorry this a long read but I really want to get my head around this… simplified questions at the bottom of the long read… I’m struggling to understand it as there’s not many videos explaining it and lack of diagrams in GN3.

    How can I teach myself inspection and testing in preparation for my AM2S?

    I have my AM2S next month, and testing is my biggest weakness by far. I’ve been asking my company to put me on jobs where there is testing work available but it rarely ever happens. Whenever those opportunities do appear, they are very quickly completed by the experienced sparks on the team...
