Installing KNX which is frankly AWESOME!!!!!!!😎😎😎 | Thomas Nagy

[@AlanLumsden]

That must be (is) the tidiest consumer unit installation i've ever seen, and i've seen a few. Well done Tom.

[@mlapamc]

the board looks so tidy, i love it

[@mikes6844]

Getting more and more like cars, just as the mechanics get reliable it will be the electrics and software that lets it down. Great job, thanks for sharing.

[@habkhal]

Hi Thomas, thanks for the video. At least one of the few on youtube that are in English. Is there a way to do a detailed KNX installation perhaps on your next KNX project. Thanks.

[@davidcollinge509]

Hey Tom I'm an electrician in canada, can't stop watching your videos even tho they have nothing to do with canadian electrical, but you do some fine work boss, keep it coming.

[@c31979839]

david collinge are you residential elec, or commercial/industrial elec? Do you see much lighting controls on your jobs?

[@kearneyboy]

That second fix didnt disappoint Tom. The D boards are a work of art. I install industrial CAN network and ProfiBus equipment fairly regularly and can see KnX/Dali appearing more often on Domestic/Commercial installs. Great work mate.

[@sparx2391]

Nice to see such a neat consumer unit.

[@deps314]

We were installing knx and recessed long light 20 years ago in my country. Welcome to the modern World Thomas!

[@stevenstroud]

The consumer unit looks fantastic Thomas, you can tell a lot about a sparks by looking at their DB board and you obviously take a lot of pride in your work. :)

[@peterjambricska3337]

Great job. Nagyon ügyes munka, most kezdem, remélem még sokat tanulok tőled.

[@billythespark7477]

One of, if not the neatest consumer unit I’ve seen. 👌🏼

[@tonfarrugia]

The board looks awesome, I like how the wires are dressed.

[@SamButlerUK]

We’re a special breed aren’t we. I once opened an old GPO box termination in a 1920s building in Manchester - marvellous bit of telephone wiring, back when people took pride in their work, unlike Openreach(around)

[@Neo8019]

I have not seen such a tidy board in the UK for a long time. Nicely done. Looks great.

[@erickkrenkindemoura7411]

Knx is innovation for residence and buildings, I'm at the beginning of my 17 year old! Brazil!!!

[@lorconhildred1591]

Nice video! My OCD was very satisfied with your fuse board terminating 😍⚡️

[@lewisbrand]

There are different schools of thought about load distribution in a consumer unit. Personally , I don't put all the high current circuits closest to the main switch by default, after all, how long a time period is a electric shower going to be active in any 24 hour period in a domestic setting ? I tend to balance the loads ( heat wise ) across the consumer unit rather than concentrate them.

[@avocado71]

Lovely wiring inside the CU case!

[@stevebrindley]

Great video ! Good look at the Knx stuff ! I miss installs like this having moved into maintenance!

[@Fifury161]

I like the effort you made to keep it neat - why don't all electricians work this neatly! Thanks for sharing.

[@JimWhitaker]

Beautiful neat work. Tidy board -> tidy mind -> tidy job (I suspect). Choosing which tradesman to ask to do a job is always a challenge; on all the available evidence, your work looks great.

[@RuneInternational]

Works alot like our Danish LK IHC and IHC Wireless. Have plenty of empty pipes in all directions. Customers always want to expand the system as soon as the start using it. That’s why we have the wireless modules now.

[@johnschlesinger2009]

Very nice! And thanks for your opinion on ring circuits. I agree 100 per cent, except where a lot of sockets are on a very long cable run, in which case an intelligently layed out ring can be better in terms of volt drop. But even then, one could start the radial with a larger cable, and reduce the size later in the circuit (a 32A could start in 6mm and reduce to 4mm further down).

[@Khanjan-si8me]

I am training to be electrician all our love to all for you . Your the best

[@lylewatts6370]

Nice, We are getting into the electronic switches too. Wifi switches and receptacles seems to be popular here. Electrical trade is going more electronic all the time as new ways to do old things. Every receptacle in a house here must be arc fault protected so that adds about $1000+ to the electrical installation bill. Love the videos and please keep they coming. Would like to see the mains coming into a house from the utility and going to the meter socket. Conduit is used to the electrical panel.100 amp services here is common for average house with 200 amp for bigger residences. Thanks from this old burnt out electrician in Canada.

[@peterwentworth9181]

Nice install. I have a wylex isolator switch which allows for two sets of tails out of the bottom. Much nicer looking than Henley blocks.

[@cargunnutuk]

Quick hack for you if you measure the current output and drop it by 25% using the correct resistor on those drivers you'll barely notice the drop in light level but the LED's will last longer

[@kaizerchief2280]

Nice neat work , keep the vids coming . Awesome 😀

[@MartiA1973]

11,000 views in 12 hours! Go Team Nagy. Great Vid - thanks Tom.

[@alvina69]

A 20-way Main Switch board... That’s one expensive board but something’s tells me money wasn’t an issue on this job 😉

[@happygilmore7115]

Nice job Tom.

[@billhickswasgreat3421]

I need to know what the recessed lights at min 5:55 are. Can anyone help me out and point me to the product name?

[@TheDaf95xf]

Another great talk through Tom 😊 I’m not an election but I find your channel really interesting and informative with fun attached to it......😆 It’s sunny out side and we’ve not seen your bike out yet lol 😆 Stevie.

[@TheMitchellShort]

That consumer unit is incredible, love it if you can share your method

[@simonc772]

Out of interest, if you don't fit ring mains, how would you wire a socket circuit where you need in excess of a 20A radial?

[@anti4354]

I don't know if there's something special about UK regulations regarding this, but in rest of Europe you just use 4mm2 cables instead of the standard 2.5mm2. Then again, why would a standard socket in a flat or house be over 16A? Just out of curiosity because I've never seen a standard household socket strip have over a 16A breaker. I would understand for devices not connected to sockets (like air-air or water-air heating pumps) to have over 16A, but never a regular standard socket where you would plug in like say, a TV. As a side note, wire size for household socket circuits are often bigger than 2.5mm2 if you have long lines, because the short circuit current becomes too low so the breaker doesn't trip and one way to increase short circuit current is to increase the cross section.

[@michaelhodges4222]

Where did you learn to wire with knx and other kinds of smart home technology?

[@ruaridhmacin]

Out of interest what band of knx stuff are you using? Controller/switches etc. Thanks

[@michal2788]

I have no idea what your talking about for half the video but its still entertaining af

[@Helveteshit]

@Thomas Nagy, 5:00 , I've installed a few of those at a large construction place. They are horribly tight for our wires. Normal 5G1.5 cables with Phase, Neutral ,Ground and two Dali. I prefer the cheaper knock off Chinese like product they opted for instead. Much better spacing and works just as well.

[@NowBeginsLife]

Scrolling through the comments - I cannot find what make or model those led light fittings are.. they are beautiful and we want them ... you point me in the direction of where you got them or their exact name ??? Please and thank you.

[@danielbairstow]

Do you only have one live/fused feed going into the KNX board? Is that because there's only one floor of lighting circuits? If you had a larger property with multiple floors and perhaps KNX heating and blinds would you have more live feeds coming from the distribution board?

[@gscott1604]

Your board is so neat and tidy, but as a panel builder in Ireland I am happy that the set-up of board/trunking/board etc would never happen here, normally contractor has a bespoke board built complete with all switchgear and knx in it together usually all wired to terminals with usually about 25% spare space for future use, it means you only have one thing to mount with one door and all in one enclosure. Board also comes complete with terminal matrix which explains all circuits. Drop me a line and I'll sort you out😂😂

[@jamesa6091]

Doddle to replace....assuming you can still get the same size/model in 5yrs or so :)

[@saabuldin]

Even if it was available, it'll be special order item at triple the price.

[@gavinhoulston7910]

It's just led strip just cut a new one easy lol

[@23bobjr]

its a custom led strip. Not a regular one

[@constantine5208]

very interesting you are connecting KNX to Dali LED driver.

[@symosys]

Great information, just ordered a few of those Contactum Defenders they look awesome. What trunking are you using between? Can you do more on KNX and Automation on this channel?

[@Ethanboyf]

That fuse board though 😍😍

[@dgb5820]

Awesomeness

[@brianoceallaigh8714]

KNX, CBUS and Dali!! Fitted a dimmer switch for an elderly couple a while back whose son recommended it would be a good addition to their living room lighting plan... Had three call back's from the couple saying it worked the odd time and sometimes the light was not bright enough!! In the end you guessed it I replaced it with the old on/off switch... Smart lighting is not for all... Guess it will take a few generation's to completely adapt to it...

[@c31979839]

Brian Kelly it sounds like it would have been better for them if you install components that actually worked instead of one's that intermittently didn't function the way it was programmed to.

[@Interlinked404]

When downloading the program to the device, the download fails and it prompts that there is an error writing to the memory block. What is the reason?

[@deathmaniac95]

Nice work!, Greetings from Chile :)

[@MartiA1973]

What's the antagonism to ring circuits? I'm genuinely interested.

[@lasseebooi]

What are those long lights 6 minutes in to the video? They are awsome, would love to have those!

[@MarcUK]

Us poor folk have to go the cheap way. "Alexa, dim the living room lights". xD

[@joshuahack3231]

🤔 Things that are fustrating in the uk.. Ring circuits, solid core cable, bare earth, 110v on site, metal back boxes 😊👌

[@joshuahack3231]

Love the videos though keep em coming

[@AbdulKhan-tq8pm]

solid cable in the uk seriously?

[@joshuahack3231]

Abdul Khan I wish someone would introduce stranded cable with an earth that already has insulation on it 😊

[@TheGreat185]

Only solid when house bashing, stranded cable used in propper electrical work i.e industrail electrical work 😉😊

[@thomasnagy]

play nicely or you will be asked to leave the ball pool!!! ;-)

[@adamjones3249]

Why are you mounting on ply?

[@robinpenny3193]

Do you have a link for those recessed LED strips please?

[@TheeJoshJ]

Why do you not like ring circuits? Do you think radial circuits are a better job?

[@promedia7696]

Do you have to have a red colourd braker for smoke detectors/fire panels as at the place that I work at thay have them

[@idi0tdetectioninprogress]

Not the breaker as such. The Fire panel circuit is kept separate to everything else, and you can label it with a red ident so its hard to mistakenly isolate it. An engraved fused outlet is installed adjacent to the panel.

[@TheEulerID]

I will only have RCBO systems. Incidentally, whilst I can understand electricians not liking ring circuits, for kitchens, utilities and workrooms 32A circuits are still what's needed for flexibility so make those 4mm^2 radials.

[@marvuz552]

Putting the heavy load from right to left? Here in Sweden, we do from left to right. To be fair you're driving on the wrong side of the road as well. Thank you for uploading :)

[@superseven220]

Gonkie you Swedes used to drive on the correct side until you made the mistake of changing😉

[@colinhaggett]

The reality is it doesn’t make blind bit of difference where the loads go. It’s just something all electricians do on single phase boards, get to three phase boards or bus bar chambers and the loads will be all over the place.

[@absolutebin4611]

It’s always been good practice to install the higher current rating MCB’s closest to the main Switch to descending current loads. We Drive on the left because predominantly most people during the medieval times as of today are right handed. So knights passed each other on the left to utilise their right hands which would draw the swords. It’s remained the same ever since. As your Swedish, you should be more concerned about the cucked state or your nation.

[@wescarter2921]

Have you tried alexa to control the lights? They can be dimmed, timed and automatically switched on when you arrive home.

[@JrgenEidem]

Which brand are the recess lights?

[@sjs202able]

Hi Thomas hope all’s good. Wondered if one day you could explain what the neutral wire does? Lots of conflicting info. on the net and everyone has their own way of explaining and would be good to hear from you. My understanding is that it is common to all three phases and is connected to the star point at the local substation. The neutral therefore carries current but no voltage as there is no potential difference as the phases cancel each other out. You therefore don’t get a shock by touching it on its own. The star point is also referenced to earth at the substation providing additional protection against shock. When connected to a load and a phase conductor there is a potential difference present at 230v and current flows. Is that understanding correct or not? Kind regards, Steve

[@jasonantigua6825]

Have you ever wired up a grow?

[@dadtothebone4859]

Yeeaahh a new video 👍🏻👍🏻

[@dplummer35]

Hi Thomas, never installed this lighting but it looks like addressable lighting, a bit like the addressable fire alarm systems that just sends a data signal to the actual fitting which you want to control....neat idea!

[@robmc3338]

[@sampegg9915]

Where did you learn to do KNX systems

[@andywarrington4738]

If the LED units are getting that hot could this become a fire hazard ? Nice to see that crazy Italian sparky does do your DB's (cables like spaghetti every where ) Nice neat boards .

[@ningis21]

Hi Tom....Nice job....Could you tell us all about the maximum demand on the 20 way boards you are installing...and do you have a 100Amp main fuse on that little lot?

[@juliannesermon8057]

Have you heard of LCN? Is it even a thing in the UK? It's a more affordable, simpler to install alternative to KNX, and I personally love it...

[@yosserg9389]

Hi Tom, what sort of training course did you do for the KNX and do you do the commissioning as well?

[@marceljoseph7416]

What's the evil of ring circuits?

[@AWolf-iv3zm]

You run DALI over the green KNX cable?

[@stevenstroud]

A. Wolf looks like, it but its not correct

[@eire4207]

Same fuseboard I fitted last week I personally hate RCBOs for terminating. Them windy earth and neutral tails are a pain to keep straight an tidy. How did u manage to keep them so tidy? Mine are usually filled with cable ties

[@alexcantley9137]

Yokes Magee cut them down and ferrule them

[@MT_T991]

Is that multiple flats. If so would have expected a ryfeild

[@stevehenke678]

What's wrong with ring circuits?

[@JasonShowell]

Technically nothing but its a lot of wasted cable. The old fashioned way of a ring per floor is just pointless these days. Every room should be on its own RCBO. That is how I wire everything these days and it gives so much more flexibility.

[@westinthewest]

Ring final circuits don't give enough additional capacity to justify the extra work during Initial Verification and Condition Reports when you have to confirm that there are no deviations from the various restrictions in the layout of spurs etc. If the ring doesn't show continuity, finding the break can be time consuming. Radials offer flexibility in their design and alteration. If there's a break in a radial, its presence is immediately apparent. A faulty ring circuit will continue working but the cables will not be protected from overload. Most socket circuits in dwellings are fine with 20A. I might one day do an A1 ring for a kitchen circuit if 4mm cable is not convenient and if the kitchen is close to the distribution board. Running two 2.5mm cables from the front of a house to the rear and back again is a waste of copper.

[@zumber2811]

4mm Radial on 32Amp RCBO is waaaay more practical to use and easy to install.

[@ratchet1freak]

it's safe against single faults but one of the failure modes is continuing to work with with reduced protection and with no indication something is wrong. For example when the live get disconnected somewhere breaks the circuit is now a double branch circuit with and a fuse that is rated at 150% of what the wire is rated at. But power continues to flow until the house catches fire.

[@JeminoWayde]

If you have a fault near the consumer unit you then have a 20A radial with 32A protection and no indication something is wrong. Two 20A radials are far superior.

[@tomtenberge]

your putting a knx cable into a dali device? i hope you mean dali on dali, since youhave a dali knx gateway... also, i see you use the of the best things about KNX, its open, so different manufacturers, your using GIRA for the psu and the gateway, and theben for the switching of the normal non-dali lamps, quite nice. i used dali in a big gym to control the lighting, in a building that has KNX, and i build out a little gimmic making the light "wave" trough the gym, now the maintainance guy can show of the lights using that. they even use that function to get attention if the break on a game is almost over and stuff, to get people back into the gym.

[@cj0815]

And mixing DALI and KNX in one cable probably?

[@benknights286]

[@tonyjones9442]

On the llyn, we still have oil lamps using whale oil.

[@Thompson-from-Finland]

Do you do a lot knx systems?

[@Elch2912]

The switches and dimmer you showed are DALI types. Normaly you have to use HV cable, not the green KNX one. Because KNX is low voltage -> 28Vdc. I dont know what your regulatory says about this. In europe its not allowed to use the KNX cable for potential High Voltage devices. And DALI wires have to be treated as they were live wires. We have here 5core cable for that. N,PE,L + DA&DA. For example: NYM-J 5G1.5

[@robmc3338]

I don't believe it's forbidden to use knx cable as Dali cable as the outer insulation is 1000v rated but I agree it's a really bad idea to do and massively is increasing the chance of miss wiring, equipment damage etc......

[@c31979839]

That's strange, because DALI here in North America is all 18/2AWG wiring. Dali only has low voltage travelling within the wires. Maybe our Dali devices have better isolation between line voltage and Dali signal than your

[@norbertvarga8621]

Hi Tom. I would much apriciated if you could give me the product name and the supplier for the recess lights. Kind regards Norbert, PS. Love your videos..

[@MrElliotCoates]

Really like your channel it’s a good insight to what it’s really like to be an electrician. You may get this question a lot but what’s the best way to be an electrician when you’re already in a full time job. Is an apprenticeship a good start or college or a home study corse?

[@tonyyoung3437]

All boards from 100A supply. Too much demand comes to mind, but maybe not too many showers and electric cookers ?

[@andljoy]

How do you fill a 20 way in a flat !

[@evilutionltd]

Andrew Joy in London, it’s never just 1 flat. 1 house usually become 4 flats.

[@idi0tdetectioninprogress]

This flat is a bit special, and it`s much better to split circuits when opting for full RCBO breakers. Tom`s made a stonking job of it by the looks of things.

[@Pugjamin]

Well he pointed to 4 AC unit breakers for a start.

[@andljoy]

Oh its a fantastic job , but when you live in an old 1940s house that has had at best 2 re-wires in its life your used to everything being on like 4 and wiring your own fuses :P replaced a few years ago with a dual RCD unit ofc.

[@tonysoprano9370]

Andrew Joy a London flat is more like a whole floor of a hotel.

[@ACombineSoldier]

I can't get my head over how they use control wiring for panels and machine cords for wiring.

[@KSSilenceAU]

G'Day from Downunder! RCBO's all the way, we used to have a single RCD protecting our breaker box but everytime something like a kettle tripped it, it would take out the all the power outlets in the house including my IT equipment, so one day when mum managed to get shocked off a light circuit, for reasons yet unknown we said, fuck this, thats it, replace ALL Outlet AND Light circuit breakers with RCBO's, problem solved, next time the offending device tripped out the RCD. it only affected that circuit. RCBO's also avoid the issue of combined leakage currents causing nuisance trips and excessive trip sensitivity. RCBO's ought to be standard these days IMO.
