    Can I omit the SPD on this rewire? + Rant

    I'm about to rewire an empty house, with no electronic equipment or anything else plugged in or installed. Does this mean I can omit installing an SPD because the value of the equipment that could be damaged is less than the price of installing the device? "For all other cases, a risk...

    Which surge protector.

    I know about type 1 and type 2 surge protectors,and which one to use. But what criteria dictates the rated amperage of the device. Are there any parameters to consider, other than the load I am trying to protect. Information on these devices is hard to come by. Any help appreciated. Thanks

    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. At least I think they have, the warning lights have come on, presumably because they've diverted a surge once too often. Is it...

    Lost neutral and surge protectors (TN-C-S)

    Would a surge protector (on an RCD) circuit protect from a lost neutral overvoltage? I know that isn't the aim of them (transient spikes only rather than sustained overvoltage) but I am thinking it may be possible (although very alarming if there isn't a thermal fuse in the surge protector)...
