    Invertor Error - FE Not Connected

    Hi guys. So, we've had solar panels installed on the roof for about 3 years now, and just recently, had an issue where the Invertor in the loft was bleeping. Went up to investigate, and it'd stopped... So, a few days later, heard the bleeping again, went up to check, and could see the...

    Theoretically... cables must be fused down when a lower size cable is connected to a larger sized ca

Yes i know this Now current doesnt go anywhere it isnt in demand for so if a spur off of say a 6mm for...

    500v Insulation Resistance Test ok?

    Hi all, still training so please forgive my very simple question. Why is it ok to test an appliance at 500vdc when PAT testing but great care should be taken to remove all equipment when IR verifying a new circuit installation? Is it simply just because connected equipment will make a nonsense...

    Inverter on earth stake?

    Been asked to replace an old consumer unit, PV installed so bonding etc up to scratch. House supply is TNCS, however with the PV wiring the inverter (Fronius) is on its own earth stake! So that makes 2 earthing systems in close proximity! Why would they want to earth stake the inverter?

    Supplementary bonding question

    hi all, I know there are many questions on this topic but I'm unable to find my answer. Can I connect my 4mm supplementary bonding cable to the cpc in my shaver socket which then links directly back to the light (and via the cpc back to the CU)? Sorry if it's a basic question, I am still training
