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
Hi guys,
So I have a domestic scenario where off peak E7 storage heating is installed.
Client has asked for a DB upgrade and has opted for surge protection.
Currently they have separate ON and OFF peak Wylex fuse boards tailed individually from the origin, the meter is 2 metres away.
If I...
Evening all,
Just attended elex exeter and see there's a big push on these SPDs coming as standard now in domestic consumer units. Hager, Lewden and Contactum to name just 3.
I have had at least 2 clients in the last few months whose appliances have been damaged by apparently surges on the...
Thought I’d do a bit of browsing on this subject and stumbled across this video from the grand old US of A by a guy who calls himself the ‘Surge Protector Guy’.. great I thought this could be informative... I watched and was left thinking ..Why?
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...

Hi there. I’m looking for some help on how to wire up a SPD for a 3 phase machine. I’ve been told by the company that supplied the machine that the SPD must not be any further than 10 meters away from the machine. The SPD connections are—- L1 L2 L3 N at the top and...
Hi guys, hopefully someones going to be able to point me in the right direction here.
We do a lot of work for a small retirement home locally that has recently decided to fit lightning protection. We've pretty much been strong armed into fitting SPD's on behalf of the lightning firm (LF). Being...
I used to fit these as a matter of course on my of the installations I did overseas, and understand that you can now get them to fit into a C/U if I'm not mistaken.
Mrs Pete999 has been whinging about getting one fitted, now I want to fit one for whole house protection, not sure of what to get...
Hi there, I have recently had an issue where there was a power cut in the village we found out that a pylon had blown. When the power came back on it caused a surge around two properties that we own in the village causing the circuit boards on our boiler to blow and the till and boiler in our...

Can anyone tell me if its a requirement to install a surge protection device to a sub Distribution Board if it serves external equipment ie a roof mounted extract fan even though a SPD is located on the Main Panel?

Try not to do PA Testing but had to do it today!
Was doing the above today after a cottage got flooded. Lead didn't appear to be wet, but failed the insulation test @ 0.7Mohms, this was at a test voltage of 250V.
Re-tried it with my installation tester at 100V and 50V and got the same...
morning all,

hi guys,
is there no such device that is sold where you can wire your two mains tails into then out to the cu to offer surge protection..say you have a dodgy supply (i know very unlikely in UK) it will just trip out and protect your appliances from burning out from 280 or 300 volts in worst...
We recently had a lightning strike. The lightning conductor workedwell, as the fabric of our Church was unaffected, but it took out our interiorLighting Control System. We managed a temporary repair to get lights on,but it took us about 3 weeks to repair the system.
I now am thinking of...
