    Is surge protection important?

    I seem to go through at least two extensions a year as the surge protection light eventually goes off. Is this because it's failed or because it has done it's job at some point?

    Really reluctant to buy another, however all my av equipment is connected to it.

    Thanks

    I have never had a surge protector fail so I am guessing it is doing its job!

    Well the green light has gone off so I presume it'd now dead?

    I always use protection on my sensitive equipment oO

    the uk has a good stable power supply. power surges are very uncommon here. realistically - your only likely to get a surge in a lightning storm.
    if the light goes out its more likely that the bulb has blown.

    So what, continue using it then and risk it?

    Had one for 17 years. Never triggered so I think not. Only ever used on pc but think it would be better on our £700 tv. We always flick switch off if there is lightning around and when we go away on holiday. I also have double pole house sockets so both live and neutral is can be off.

    Never had one never had an issue

    Yeah - they don't last that long, I have a Belkin 6 way that didn't last long, Googled it ages ago and apparently you're meant to replace something in the unit if you want to keep the surge protection.
    But we have a very stable power supply in this country, so unless you have very sensitive equipment you don't really need it.

    ​Same. Snake oil, those things.

    As previously stated

    Never had one - only had rcd protection for external gardening equipment (mower/strimmer)

    and

    The UK's supply is highly regulated and very rarely causes issues requiring surge protection - unless you've got a few £k's worth of specialist electronic equipment then I'd ignore all the sales jargon stuff. Your home insurance will cover any other issues except data loss.

    Just ensure correct fuse for device is fitted and sockets are not overloaded.

    ​I've no idea what muppets marked you down but yes, if the green light is out then the surge protector has burnt out. These normally last around 4 years hence the limited guarantee with them.

    The area where I live has black outs every so often so for me they're a must. Remember that these devices wont protect you from a direct lightning strike and only for low level surges. Robust electronics should be fine but these devices with small switch mode psus will take a bit of hammer.

    Surge protection is is like insurance,if you need it (as I have) they are both worth their weight in gold.
    Why do you think new houses have it built in from new.

    I read a very long and in depth article on is it worth having a surge protected plug board from an American chap. At the end he came to the conclusion if it gives you peace of mind then buy one, will it actually save your equipment if you have a modern day consumer unit mostly likely not.

    They're only really useful for odd small spikes and nothing crazy. Mains voltage unlike frequency flutuates so it's not really 240V but 230V +10% to -6%. Pretty much you could be getting anything coming through the mains or even get a brown out where the voltage drops.
    A lot like static damage your devices are less likely to die but to degrade over time. A lot of people wont see this though as we swap electrical goods that quickly.

    Effective protectors do not fail. Near zero joule protectors (with an obscene profit margin) fail. That gets the naive to recommend it and buy more. Since an effective protector does not fail, then a majority do not even know a surge existed - cannot recommend it. They do not learn how protection, even from direct lightning strikes, was routine over 100 years ago. This proven solution costs about £1 per protected appliance.

    What are the risks? Honest answers include numbers. A potentially destructive surge occurs maybe once every seven years. Much less often in the UK. However that number can vary significantly even in the same town. Factors such as geology, utility connections, and even nearby long distance pipelines can change those numbers. A neighborhood history of more than 10 years is necessary to say more.

    How often have you replaced a dishwasher, RCD, furnace, LED/CFL bulbs, clocks, dimmer switches, and smoke detectors due to surge damage? All those and even a refrigerator need that protection.

    More numbers. A direct lightning strike is typically 20,000 amps. So a minimal 'whole house' solution is rated at least 50,000 amps. Any protector that fails is ineffective protection.

    What does that light report? A grossly undersized protector circuit had to disconnect as fast as possible to avert a fire. While leaving that surge still connected to attached appliances. A surge too tiny to destroy an appliance also easily destroys a near zero protector. That gets a majority to recommend and buy more 'profit centers'. When damage does happen, they wildly speculate, "Nothing can protect from lightning." Reality over 100 years ago says differently. But that means learning from experience tempered by well proven science; not from hearsay, wild speculation, and advertising.
