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...

That consumer unit is not 25 years old, that would make it 1999. We were on 16th edition regs back then and a few things were different. The whole all metal consumer units thing was 2015, before then, you could get metal but there would be plastic flaps on the front most of the time. BG were not...

I've not heard of that happening with ABS type plastics, but there are cases of it happening with the phenolic type platics with cutout fuse carriers becoming live if its suffered overheating over its life! (rare, but happened enough that its got its own fault refence code on the sheet that the...

Just a normal half round file, Pinch the edge of the return to taper it down to nothing at the end, dress with file, if available, finish with some sandpaper (be careful not to rub the surface and take the galv coating off) finish with a bit of cold galv spray

Obviously the other downside to sub metering and charging them yourself, is that the tennents would then have no choice in tarriffs, maybe that wasnt a big issue 10-15 years ago, but now you can have things like agile or tracker which some people can save a significant amount on over standard...

You need to make sure the lights are on an RCD before you start adding sockets to it, provided they are, you'd be well advised to mount the socket out the way and make sure you label it somehting like "CAMERA PSU ONLY - SUPPLIED ON 5A CIRCUIT" You can get a permenent feed off the lives in the...

BG actually do a 1Module compact RCBO that breaks the neutral, but thats not what is shown in the pic https://westbasedirect.com/products/cucrb40dpa?variant=41386457563341 Pic shows CUCRB40A which only breaks line. You need CUCRBDP40A for an evse. Although its missleading I think to refer to...

An Un-sanded dog kennel?:unsure:

No, only having one end earthed will result in higher loop impedance, which could in some edge cases make some overcurrent devices less likely to operate, if the fault itself has a significant resistance. (Thats a bit of an asside and not really revelant to your question) But not earthing the...

Other than it would be a little awkward to make the busbars work and would probably require a short tail and a connection block. Presented with that arrangement ofincomming conductors and single neutral block. I guess electrically, there would probably be nothing wrong with having a three pole...

When the supplier's metering company fits the two extra meters they will sort how they are going to terminate the neutrals. You electrician will sort out how he's going to terminate the earths when he puts the switch fuses in and completes the rest of the installation. The cutout is owned by...
