Leaving extra length of the armoured would make the job easier i believe .. Well done sparky 👍

great vid. Ive got to do one this week. what's the general thoughts on running the swa up the cavity?? If i cant get it up the cavity then I'm going to have to chase it into the block behind the dot and dab :/

DNO fuse is to protect the installation as a whole metering etc, the additional fuse is required to protect the cabling to the CU. Not required if CU is closer.

So is it purely because of the distance then? I think a saw another video about the same thing earlier today

Assuming the DNO puts a 100a in... your fuse needs to be max 80a. Selectivity and all that 👍

DNO will only fit 80a fuse in cutout. Your 100a fuse pointless. Really needs to be 63a to allow for discrimination between household circuit and DNO supply.

@robtmcL12

I'm DNO and can confirm we have recently had instruction to fit an 80 amp in the 100 amp cutout. The reason being it will allow 120 amp + for a few hours. The time/current curve for the BS88 will confirm this. As for discrimination, you don't need to bother. It's 50/50 which one will fail first and if it's the DNO one that gives up first, they will respond within 2 hours anyway. In some instances ( flats with submains ) we use a red fuse link in the flat as there's already fuse protection in the Distribution board ( eg Bemco/Rapell/Schnieder boards ).

What grips did you use please

Why was it not an 80amp fuse upstream of the 100amp main cutout? Descrimination/ Selectivity and what not

The meter provider won’t touch it. They don’t connect to a de-energised supply and on the basis there’s no room for an isolator, they’d walk away.

I've done a couple of these, it's easier to curl the wires at both lod and supply side. I always leave length on cables just in case and it looks just as tidy. Not sure why earth nut or banjo wasn installed from source side as less likely to get tampered or disconnected 🤔

@sebastiannielsen

Tampering with Earth or Neutral won't in any way get you free electricity, it will just make the life more dangerous. So putting them on "consumer side" is actually preferred, since then if the consumer or any electrician needs to make a measurement on for example earth or neutral, you usually need to separate these (NOTE: Very dangerous, should be done with isolated supply) and then you can measure, for example, track down cheater earths (cheater earths are when you make a fake earth out of the neutral on a socket - super dangerous!) - this by connecting a beeper transmitter on the now disconnected earth, and then making sure every socket beeps. If a socket doesn't beep, its a sign that the earth in that socket is fake. Disconnected neutrals and earths also have other usages, measuring resistance to find out cable lengths and impedance, tracing broken earths and neutrals and lots of other uses, and it would be a pity to have to call DNO or meter company just to do some troubleshooting on earth or neutral. So always leave earth and neutral easily accessible on consumer side.

Do you not usually use the grey for the earth and black for neutral or doesn’t it matter as long as it’s sleeved?

22/58 100a fuse is an European style industrial fuse NOT a domestic 22/57 house service type. Any short circuit fault would blow the DNO fuse and not the one in the switch fuse,I've seen this happen before,these fuses have a much higher watts loss and pre arcing values are higher

Those switch fuses are pants, just no room in there. I always buy the Wylex ones ,plenty of room in them.

This is technically not true in this case when a consumer unit is more than 3 m away from the main head there has to be an isolator of some kind

@@temp06j723-pmeighttq Because my understanding is that the cable size and fuse should match the setup. The DNO fuse is 100 amps. The tails are 25mm which support amps of over that size of use or thereabouts. If you then are going to build a distribution network then the DNO then expects you to go lower in cable size and fuse to protect their fuse. A 25mm cable matches the tails which isn’t the correct way to build a distribution network hence the question. I think the distribution network needs to be lower cable and fuse so that if there was an issue on it then it would protect the DNOs fuse and setup but I’m not qualified and learning so if you know the answer I’d be glad to hear it.

DNO's cabling protection is another complex story. CutOut is to protect Meter Tails etc. When given a 100A service Cut Out, you wouldn't be fitting a 16mm² Tails unless you Downsize the Switch-fused Isolator + fuse to a 80A then it will be fine. But then it will be a waste, considering the ability the DNO to Service up to 100A yet we downgrade our PERMANENT Cabling(meter tails) to a lower size that Forever is Binded/capped to 80A in the future (with using of 16mm²). Hope it makes sense.
