Hint for the lines on the Wires: I usually use a thick Line to indicate 5 Lines, to make counting easier (4 same sized lines is the upper limit of what you can easily count at a glance. but 7 Lines could easily be confused for 6 and the other way around).

I tend to use one along the length of the cable rather than a thick line.

[@AintBigAintClever]

Any regulatory reason why the Wagos are in LNE sequence rather than LEN which would match the T+E cables? Other than that, as long as cable bunching as part of the relocation doesn't open its own can of worms they look like a good piece of kit. I expect that high IP rating would also come in handy to correct some of the more controversial installs seen on KZbin, where for example a room's been turned into a bathroom but the CU's still in there, just behind a panel.

Are these relocation boxes maintenance free so they can be hidden in the ceiling? Or would I be better to use MF junction boxes on all the circuits maybe?

[@-Xaverius]

Hello, I have a quick question about the regs, I am thinking of having the consumer unit modernized but would it be possible to place an isolator switch between it and the mains? As this would make it much safer to work on it afterwards.

[@reeceoverton1421]

Yes

[@AintBigAintClever]

A REC isolator is what you're looking for. Despite REC standing for Regional Electricity Company they're not the sole supplier of them; even Screwfix do them (part 321FR). There are also 3- or 4-pole versions available for polyphase or Economy 7 installations. They also make it easier if the tails to the new consumer unit would need to be extended, as the existing tails can simply be brought into the isolator and new tails run from there to the new board. No opening of the meter cover, no tripping of the meter cover tamper switch.

[@deang5622]

Many CU's contain a double pole isolator. You don't necessarily need a separate one.

[@Martin37vg]

If you struggle to find the Wago range, Phoenix Contact make the same and I use the pre-printed circuit identifier label that clip in just under the small squares which are used with bridging combs to common up terminals. You could also mention the test point just above those squares. I use these extensively when building control panels, they are great.

[@OldLordSpeedy]

Yeah, the products are equal - but Wago offer different sizes same Phoenix Contact. They offer 1to2 terminals too - so you can put a ring to this box and use one line to CU only. I think for more as 4 mm² (specially more as 10 mm²) is this a better solution. BTW: For testing are the holes - the red square are for put together more as one product with special nuts. 😉

Wiska Consumer Unit Relocation Kit FFS IN REAL TERMS A JUNCTION BOX

[@gbelectricks]

Got a board change tomorrow morning, I’m going to use a sharpie to number the line conductors. I usually flag lines with insulation tape, its a nuisance if a tape breaks off whilst removing the old board👍👍

[@mra813]

I have been making these for years using an adaptable box and Klippon terminals.

[@effervescence5664]

Seeing this reminds me of the one Artisan did awhile back where they took radials from the new CU to one of these boxes where the rings where. Thankfully labelled up to test in future from the Wiska CURK. That said I feel like unless you can get 2 separate din rails top and bottom in there it's not actually big enough for most properties, not to mention if you have to size down for fine stranded conductors, wouldn't you just ferule them? Yes you can join the protective bonding conductor, it's just down to jointing method, my preferred methods are crimping or brazing. If you could run a new cable that would be preferred but cost and accessibility are the limiting factors.

[@pel787]

They need to just make a bigger box with more ways, much cheaper to buy an adaptable box and a box of wagos

[@h8ryj]

Brilliant for an installer, makes life a hell of a lot easier for sure.. I made my own one with din terminals a little while back to extend couple of ring main circuits. Downside will be its ugly and customers will not like a grey box housed on a wall in a hall way or lounge. Perfect for understair cupboards or housed in boxing in. 👍

[@Rosscoff2000]

Wherever it is, it will probably be less obtrusive than the CU it's replacing!

You can extend a main equipotential protective bonding conductor if you use a crimp connection. Same would apply to the earthing conductor

[@Blackf1ngers]

While the regs do not demand that this sort of enclosure be made of metal wouldn't it be better? It doesn't make sense to me to for a plastic consumer unit to be replaced with a plastic DIN rail enclosure considering the amount of connections.

[@gibberingidiot]

While this looks a nice idea, it's really only going to be useful for moving smaller or older boards that don't have too many circuits on. Given that RFCs take up two sets, it doesn't have to have many before there are not enough connections. (Yes you could mount two side by side but then the original cables likely won't reach into both) I've just relocated a standard 10 way Dual RCD board from a hallway to a cupboard for aesthetic purposes, and this would not have been adequate (3 x RFC, Oven, Shed, 3 x lighting circuits) even though the original board had two unused ways. Hopefully in time suppliers will stock wider boxes and let you mix and match the connectors to suit.

I would use a crimp connector with a bit of heat shink for extending a bonding conductor so it can be said to be permanent.

[@acelectricalsecurity]

[@OldLordSpeedy]

The problem is that the grounded earth/saved earth was in the history one point for all together. It was never a problem to bonding it together till we create RCD's. I wonder why Wago not produce yellow-green products same the gray or blue in plastic only. A plastic DIN-Rail is a wonderful solution but IMHO not a correct way. I self would let in this parts how I use only, empty Wagos looks like something forgotten here. Do you can buy numbers for the Wagos so count it 1,2,3,4, aso. Then the table looks exact correct - nobody know the next electrician put it under or left and right. The only problem are the UK fire rating where do you should seal the hole. I am unhappy that CU should be metal for fire safety but here plastic is okay. Do you have crazy regulations in UK. Just a hint! 🤔🤑

[@zoltrix7779]

I would have thougt that a non bonded version of the DIN rail connector would be available in earth colours.

I confeus (You removed the all breakers ) you tell clear .. This is a breaker? If are shot circuit .so ther cut off my indoor spley ?

[@boblewis5558]

Just a question that only just occurred to me ... Why "move" the CU if all you're going to do is replace it with **another** box occupying the same space? There are usually two reasons for wanting to move a CU: 1. Convenience of a better location 2. Being able to free the space occupied for **other** purposes This method provides no help for the latter however. Isn't it about time that extending cables with appropriate simple, reliable, in line connectors was sorted out? The poor consumer has to pay enough for Microsoft bloat without domestic wiring doing the same! 🤔🙄

[@mikewhite5936]

the 2 reasons you gave are 2 of the least used due to cost of relocation the most common 2 are home renovations/conversions and the second is because the current consumer unit is no longer fit for use and the new one wont fit in its place so the new one has to be installed only a short distance away the fast connections of the wiska allow for a regulation approved connection meaning your home is in less chance of (a) catching fire or (b) having wiring faults. sounds a good reason to hit the consumer with another small charge instead of him paying a large bill out in the future us sparks are only looking out for ya wellness.

[@ms.electrical]

Be good if it was metal not plastic being as we have to fit a metal dB .....

[@smitcher]

Those are great bits of kit, especially the ones with the lever Wago connections on the lower side. If I were to criticise one thing though compared to the previous box - I personally would have installed washers with the fixing screws to reduce any chance of the screw being pulled through if it bets bumped but other than that it was a flawless install!! Maybe i'd have left the wires a little longer too but that's just down to personal choice...👍

[@eeyxeb]

If I can remember rightly there is something in GN8 about main protective bonding conductors needing to be unbroken. But I'm sure somewhere in the Regs it contradicts that by an exemption if using MF connection or appropriate compression joint and it also being accessible for inspection.

[@xcruell]

I recently found this channel and i'm really pleased with the quality! Thank you guys :) Ahh finally someone who pronounces Wago the right way!

[@solidus784]

I might be being stupid here, but I don't see the purpose in this. You still have a box on the wall and are running cables to the new location anyway. Why not just put a larger board in the same location and run the additional circuits back to it.

[@GeeTheBuilder]

Agreed it would have been useful to explain the reason to move the consumer unit. Usually I see this solution, as in my case, because the existing runs won’t reach the extra few inches to where the new Cu needs to be mounted. 🤷‍♂️

[@steve11211]

With things like SPD's and the increase in circuits sometimes you need a larger board, some older boards are put in cupboards or even the meter box where even if you wanted to there physically is not enough room so the consumer unit needs to be moved.. It is relatively rare..

[@yngndrw.]

As you've mentioned in an eFIXX video back in April 2021, regulation 421.1.201 in BS7671 (17th) states that "Within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439-3 and shall: 1) Have their enclosure manufactured from non-combustible material, or 2) Be enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12 Note: Ferrous metal, e.g. steel, is deemed to be an example of a non-combustible material." For the purpose of the regulations, does the Wiska 818 consumer unit relocation kit not come under the classification of "similar switchgear assemblies"?

[@zoltrix7779]

Hmmm... interesting. But I guess is not a switchgear assembly. Its a junction box. That is how I read it.

[@yngndrw.]

@@zoltrix7779 I should start by pointing out that I'm not an electrician by trade. To me it seems that in order to understand the regulation it helps to consider exactly why it exists and how there might be a difference in risk. I believe the following are the main drivers for this regulation specifically targeting plastic consumer units: 1) Consumer units in the UK are typically located in hidden areas (Under the stairs) or fire escape routes (By the front door, a hallway or under the stairs). 2) The risk from a large number of screw terminals (I.e. Not maintenance free). 3) The presence of particularly high currents in comparison to other locations. (80/100A for meter tails / bus bar, shower / cooker supplies) 4) The presence of MCBs which have to break high fault currents. I'm not entirely sure if all of these are drivers for this particular regulation, nor am I sure exactly what ordering they would be given or if I've missed any. Consumer unit relocation kits would appear to me to suffer from a couple of these risks: 1) They are typically used to relocate a consumer unit from an older traditional location and therefore remain located in these higher risk areas. 3) Not quite the same risk as the supply doesn't pass through this, but there are typically still going to be some high current circuits. #2 is not relevant for this Wiska 818 as maintenance free terminals are used, but if regular screw terminals were used then it would also apply #4 is not relevant for relocation It's an interesting point you make about it being a junction box, where do you draw the line? Is this a special case due to its location and higher currents?

[@zoltrix7779]

@@yngndrw. I don't disagree with your points. It would probably be better for the regulation to cover this scenario specifically. The electrician really, should not have to understand why a regulation is what it is (even though, in practice, they do understand why most regulations are what they are for due to training), just follow it to the letter, or at the very least, to the best of their ability. I don't think it is clear enough to expect an electrician to use a metal enclosure. However, I am sure many would choose to do so, just to be on the safe side.

[@efixx]

The connections in the junction box are simple through connections. In a consumer unit you are distributing power from higher current terminals to lower current ones.

[@alan2804]

@@efixx Interesting point but where do you stop, would a spur off a socket on an RFC come under the metal enclosure requirement as there is switching and higher to lower current circuits?

[@faisalmoghal4055]

Would it make more sense to prep the enclosure with the new cabling in the connectors before offering it up? Makes it a lot easier to handle the cables rather than working with it in situ. Obviously it depends on the installation and where those cables run to after the trunking

No breakers though ... Apparently the "source" of most CU fires by all accounts ... How ironic is that! Duh! Kind of makes my point that I have repeated ad nauseam for years ... Fit a disconnect temp sensor INSIDE the CU. Plastic needs a source of extreme heat (>200°C) to ignite. Remove the source of overheating LONG before it reaches that 200 plus temp (say 75°C) and PREVENT a fire from ever starting in the first place! None so blind as those who will not see!!
