The cables we use for wiring up our houses in the UK can be quite stiff and springy. There is a knack to wiring up a socket, from experiance struggling to wire up sockets for ages, before watching the pros do it and figuring out the knack, the following are the usual things that make it a...

Power supply leakage.

Class 0 refers to equipment that is not "single fault safe", that is a single reasonably foreseeable fault could render the enclosure live in a way that will not be disconnected by protective devices, I'm pretty sure class 0 equipment is not supposed to be sold in the UK/EU. Class 1 achieves...

Earthing provides a path for fault currents, tripping a breaker in the event of a fault, that is better than the fault causing the case to become and remain live. However, there is still a brief window between when the fault makes the case live and when the protective device trips. Furthermore...

In principle they can. In practice, actually installing class 2 metal lights to existing UK lighting circuits while maintaining their class 2 status is problematic. Often resulting in those lights being installed in ways that effectively render them "class 0".

AIUI the problem with immersions is you have a very large screw thread in a relatively thin tank with the result that sometimes attempting to unscrew the immersion can tear the tank, at which point you have a large emergency plumbing problem on your hands.

Interesting article, I'd guess some style guide required an image on every article and some non-expert skimmed the article and tried to draw one up.

I don't know where precisely that image came from, but it happens all too often that a supposedly reputable oganisation puts out content written by some hack who doesn't know what they are talkig about. Does anyone remember the shining turd that was the IEC "world plugs" page. If they can't...

IIRC if the situation with the cutout is deemed unsuitable for live-working they will usually dig up the service cable and cut it to isolate the cutout.

For works done "dead" I would think the phases of a work most likely to cause "more disruption than planned" would be when you try to disconnect a section and/or re-route power and/or move customers onto generator supplies at the start of the works, and when you try to re-energise that section...

But concentrated on the hours when planned works happen, and particularly the hours in which planned works start and end and hence network switching operations are performed. I very much doubt that if you plot unplanned outages VS time of day you will see a uniform distribution, but what the...

I expect that some are more random than others. There will be failures due to random events sure, but there will also be failures due to overloading (which I'd expect to happen either in the morning when people go to work, or around teatime when they come home) and failures due to planned works...

I think the problem is it's hard to give specific advice when peoples circumstances are so widely variable. Do they live urban or rural? Do they drive? What is their budget? Money no object - solar system with batteries and islanding capability to maintain power. Starlink to maintain...

Basically anything electrical, is the "service head" and meter still there? if not is there a largeish cable somewhere that looks like it has been "capped off"? or a run of wires on poles? Note: in the UK wires carrying domestic mains voltage on poles are usualy either bunched or stacked...

Neither the 221 or the 222 series of lever terminals have a four-position connector. They do offer some four position push-ins though.

Wago terminals are designed for a single conductor per hole. Doing otherwise would be going "off-label". Now I don't think there is anything in the UK that outright forbids going off-label (heck for many years we all used terminal block that came with bugger-all in the way of labelling or...

Not sure what you think was "strange" The sharing of current is proportional to the cross-sectional area of the conductor but the surface area of a conductor is proportional to the sqaure root of the CSA. So with conductors in paralell the larger conductor will tend to overheat first. I would...

The (recently discontinued) "schnider lisse" range of switches came with a loop terminal (or sometimes multiple loop terminals) to park your neutrals in. Not sure if any ranges still in production do.

I don't know if it's "proper" but the soloution my parents and I have used to this sort of problem is to screw/nail extra wood to the fence panel to fill the gap.

In your particular case no. BS7671 nowadays specifies (with some exceptions) a maximum protective device rating for ES/BC/SES/SBC lampholders of 16A. It doesn't specify anything in particular for light fittings without user-replacable bulbs, but in the absence of other instructions from the...
