Sliders mate

@@maddog-na3685 the sliders that link the bus bar to the rcbo

They make good fire proof silicone too you should have hanged that on the wall and acted like it's a fuse board

@@Jordan-yc3fs yeah they called sliders not little isolators john

@@maddog-na3685 you even a spark or did you just sleep with one. People have different names to stuff

he is from Austria orgionally

Not an electrician, but I believe I know enough of the UK regulations to answer your questions: Not actually sure about the switching of the neutral. Our meter tails are double insulated, but additional protection is only needed for buried cables - The reason for additional protection when buried is because you cannot see where they are. The protection can be conduit and is either there to provide an earth so that it trips when you drive a nail through it, or to provide physical protection. Armored (SWA) cable is an option instead of conduit for buried cable, but not in this case as they are meter tails which must be double insulated singles in all cases to the best of my knowledge. We also have "safe zones" which define where cables are expected to be run within walls, defined by the switches and sockets that you can see on the surface. Any cables running outside of these zones must be run within conduit for the same reasons above. The focus is on showing where cables are so that you can avoid them. Yes this is a 415V / 230V installation, but remember that with the higher voltage comes lower currents. There's nothing wrong with MCBs and RCBOs in this application, the main isolator is rated to 125A per phase and it looks like the largest MCB he's used was 32A as far as I could see in the video. It looks like all of the exposed branch circuit wiring is using armored / SWA cables, although it's unfortunate that proper glands weren't used in this installation. Plastic consumer units have not been allowed in new installations for a while now, since 2016 I believe. We use metal now and the one shown in this video is no exception. What's wrong with busbars? These days they are all covered and you're going to get a far more reliable connection than looping a wire between each circuit breaker. Electrical safety is taken very seriously over here. We have fused 13A plugs, 13A plugs which prevent accidental touching of the conductors as you remove them, 13A sockets which are always shuttered, RCDs on everything with few exceptions (At least in a residential setting).

@@yngndrw. In the united states we must use molded case circuit breakers they are rated 10,000 AIC of fault current.Main breakers even in residential settings such as 100 ,200 amp are rated 22,000 AIC. In most single family US residential settings. You have a service drop overhead or a service lateral underground this first goes to the meter socket[ the meter is round and has 4 spades on the back] this plugs into the meter socket from the meter socket it hits the panel within 5 feet .Some meter sockets work like this you take off the cover lift the leaver to the right of the meter up this spreads the clamping jaws putting the meter socket in bypass mode with the main breaker opened you can safely put the leaver down. You just killed power to the panel.For your panel the meter would have 7 spades on the back 3 phase 4 wire wye. The meter socket would be the jaw clamping leaver bypass type in my area . From any meter socket in my area you would have 2 inch rigid metal conduit going out of the meter socket box to your 200 amp main breaker panel your main breaker would have to be ratted 22,000 AIC and sometimes even higher. If a breaker is rated 10,000 AIC and you have 22,000 AIC at that breaker ITS GOING TO EXPLODE AND DO VERY SERIOUS DAMAGE. This is why in the US we NEVER protect branch circuits with miniature circuit breakers like you show in this video. If i used your breaker box you show in your video in the United States the inspector would consider is as very dangerous and demand i use a panel containing molded case circuit breakers. I looked at your video and the main isolator is 4 pole which means your breaking the neural conductor which is a big no no hear in the us. In the Us starting 2020 code cycle the main breaker or a fused disconnect [isolator] must be on the outside as part of the meter socket [meter main] or mounted next to the meter so the fire department can cut the power to your burning building. Your double insulated meter tails in the Us would be a blatant code violation at the very minimum those would have to be a part of a multi conductor cable. In the installation in this video being 415 volts 277/480 volts in the US those tails would need to be in CONDUIT no exceptions. In the US the installation in this video would be considered VERY DANGEROUS and get red tagged instantly. I enjoy looking at electrical wiring in different countries this is very interesting to me. Since your part of Schneider look up SQUARE D QO load centers and Square D panelboards for the United states . The panelboards rated 277/280 have CURRENT LIMITING BRANCH BREAKERS from 15 amp on up all molded case.This stuff is WICKED check it out. I like Square D QO because the 15 amp breakers will instant at 150 amps on a short in one cycle .These things are WICKEDLY SAFE.

EspenTremonti That gland has 4 ways in the rubber, wiska make them!

This method eliminates the possibility of Eddy currents that can occur when using single entry for each conductor through steel plates..

What IP rating do you think the bottom of the db should be?

Mr Badger ip2x for side and bottom ip4x for top ?

@@paulb4423 so you are saying that the magnetic fields of each phase will cancel them out. Using a cable would have been a better choice. and still with one gland for the cable. The magnetic field working on this fusebox is negible due to the size of the current passing through the conductor. .
