    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

    So I have been asked to provide surge protection to a group of sockets in a PC area within a house. The sockets (7 doubles) are presently supplied from an FCU off the ring final. An easy solution would be to replace the FCU with one with surge protection built in. Problem is, they don't seem...

    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.

    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)...
