The requirements of the schemes generally come from the EAS, there is a document here: https://electrical.theiet.org/media/2726/eas-21-478-revised-eas-october-2021.pdf which explains what qualifications they should be accepting

I think in the end, it was decided that the client didn't actually require the switches, they had not been able to opperate for so long, that they'd just been left on for however long it had been, so I beleive they just got linked out and blank plated in the end. If they had wanted to keep them...

Whats the load? if its lots of electronic equipment with switch mode power supplies, then equipment being in standby will not make a difference to the inrush, the capacitors on the inrush stage still have to charge up, I expect you'd get the same if it had been off at the mcb for more than a few...

But saying that, I had a much worse experience once, with NPG again (The border betwen the Yorkshire and East Midland Supply board areas passes through the area in which we work - and its not quite where you'd expect it to be). It was in a smallish shop, the pressure fuses on the CT metering...

I think there is someone with an electrical background reviewing the tickets raised by the call handlers, at least at Northern Power, I can remember an interesting PME fault I had where there was about 180v between the DNO PME terminal and the physical ground, 5 minutes later, I got a call back...

Why? As long as its in good condition then its a perfectly serviceable board and if the lack of RCD protection to the lighting cirucits is an issue then a couple of Wylex Miniture RCBOs will fit that board and can be fitted within half an hour. Its alright saying hes a landlord, hes earning...

We are working for the managment agency that look after the property for the landlord, not sure they are the same one as five years ago, but apparently she was told it was unsatsifactory by the guy doing the EICR but no one got arrangeed for remedials. I get the feeling a lot of these may be the...

But it always used to start at Red for any complete new edition of the regs, starting the 18th on Blue was unusual and likely because they hadn't been allowed to finish the 17th off without their workaround, and that would then mean that they never issued any blue or brown books again. I've...

As far as I understand it, a British standard is only allowed three amendments before a new version must be brought out, 14th and 15th were prior to it becoming a British standard so not relevant and if you look at your screenshot more closely you can see that it seems there was a bit of...

Think the boards were still going in as late as about '89 so could be anywhere 70s - 80s. The writing on the breakers is a little clue to the age, originally white, later ones were yellow, with the white being M3 breaking capacity and the yellow M4.5. All breakers were to BS3871 type 2, however...

Personally I'm happy with the standard type shower pull isolators in a lot of situations, generaaly to swap out to the crabtree style you have to mess around with where the cables come through the ceiling, so I don't often use them on maintenance work. The situation I feel they come into their...

Do you mean he has something which resembles the ironing board fixed into his boot lid? :ROFLMAO: How old is he?

Mine had jumped from £515.50 last year to £697 something on renewal. Which was odd because the same insurer was comming up as £633 on go compare (for the standard policy/5 stars defaqto rated, not the cut down esstentials range that cuts things like hire cars and legal cover out etc), some other...

Might need a few shooting stars up there..... #smash mouth

However, there are many ranges all badged schneider, from both the Sqaure D and Merlin Gerin ranges, and it can be a little confusing to ensure you are ordering the correct range, hell there are even two versions of acti-9 RCBOs and backwards compatability only works one way with them!

Unfortunatly I beleive it is a rule governing British Standards, however I think they used to do a a fresh version of the british standard that didn't co-incide with a new edition number: 16th edition was rreprinted as BS7671:1992 (red cover) then became BS7671:1992+A1:1994 (green) then...

Stop giving the plumbers ideas!

I take issue with the rather generic "Circuits require RCD protection C2" without any further explanation of which cirucits (and therefore where the requirement comes from) In my view its multiple issues: Sockets without additional protection likely to supply equipment outside is always a C2...

I'm not sure the vitesse is the right bit of kit to shoe horn in there, unless you are also ripping out the kliks and putting it in its place. You have four outgoing channels from the old delmatic, do you have emergencys on them all or just one. Looking at how its wired, you have three reds...

This notice is near the 800A main panel at one building on a customer's site, below it, is the main earth bar and there is a disconnectable link at both ends: This doesn't seem to make a great deal of sense to me - how do the genrator windings end up in the fault path for something supplied...
