    Surge protection

    Morning all, Quoting for a garage supply and I’m needing too add an additional 1 way board too supply it. Due to space in existing board. Is surge protection required for such a job if I don’t undertake the risk assessment? Or only required for board change and rewires? Thanks in advance

    Advice on surge protection

    I've got a fair bit of computer equipment at home which I need to protect as best I can. I use surge-protected extensions and these have been needed a couple of times.
