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

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

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)

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.

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

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.

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.

Yokes Magee cut them down and ferrule them

Do tell more about it please

Pre apprenticeship course then look for a apprenticeship jib should be able to help

thanks

Love the videos though keep em coming

solid cable in the uk seriously?

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

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

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

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

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

its a custom led strip. Not a regular one

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.

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......

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

ralphsterz on the llyn we still have oil lamps, using whale oil.

Jamie Porter the light wave rf software is a load of crap. Very outdated

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.

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.

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

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.

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.

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

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.

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

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.

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

Jan Henkel I was thinking the same thing, here in belgium we use also 1 board. I use de eltako switches were you can connect an all-on + all-off swtich

Here in US, we use 3 phase, or "rails". I'm not sure of the benefit of running them horizontal? 208 on 3 phase, 120/240 in single phase, and 277/480 for our lighting/ motors/vfd's/etc

@@pure3nvy272 didnt see the video but pretty sure they are talking about the rails where you physicaly place the cables not the phases of the current

Dont forget the 30% Backup place inside the fusebox.

Lutron Beats both

KNX over Cbus and Lutron!

I attended a TAFE collage that built their own. Effectively each class room had a DOL for the lights. 1 click half the lights the next click all the lights, using nothing but relays.

Dean Reddy you're only paying for a Lutron name. Once your system is installed you'll be paying exorbitant amounts of money to get one of Lutron's techs in to your home to change any setting, or troubleshoot is anything goes wrong. There are so many better systems that a Lutron system in any kind of residence like this.
