We use this type of terminals 15 years ago, we swapped to Wago clamp terminal for speed and long lasting. A clamp terminal will keep the wire inside when you have vibration and a screw therminal need to be screw again to secure the connection once a years or less often depending on vibration. The clamp termnial save us so much time when wiring a new panel it's incredible.

I used a DIN cabinet when I changed my consumer unit. I actually installed the DIN cabinet on a small piece of plywood next to the new CU and ore-wires the DIN rails to the MCBs on a bench. Much easier. Then ripped out the old CU, installed the plywood as one and terminated the house cables to the DIN rail connectors which were all labelled and ready. Looks nice and neat and the CU swap was much quicker - it needed to be for my situation. It was my house.

I have to confess I have never seen brown, grey or black terminals and deffo not red. Usually a sort of olive fawn colour. I am surprised as are other followers of yours JW that you are not using end locks. I always use the bootlace ferrules on the control cables when I wire these things up, much neater and easier to fit wire into terminal. Have come across these terminals in days of old where strands of wire have been cut out to ensure too large a cable fits into terminal... lol. Good vid as usual JW, cheers

I have used thousands of these all makes all sizes alough the big ones 70mm plus tend to snop off. There is one point I have spent a lot of time in panels when they have been installed upside down when the springs age and work loose if on the rail the wrong way round any vibration causes then to fall off with obvious consequences this is even more of a problem with G rail which will lock the correct way but fall straight off if inverted. If you look at the bottom of those terminals you will se they are known as universal ie they will fit both top hat or G rail (asymmetrical) rail. If ordering make sure which type of rail they are for.

Yep, especially when you crank down on the screw on the earthing terminals to get a good bite on the rail, they really open up. That's why its always nice to like you said, put an endstop. Preferably an endstop with an embedded metal strip in the clip so it bites the rail as well and stops it from sliding down over time. Allen Bradley as well as Electec (ABB) are the end-stops I like as they have this embedded metal strip in the clip. The A/B ones are kinda sharp and they REALLY bite into the rail. They don't slide at all and if you try, they dig into the zinc coating on the rail and get even more secure.

I have the older style , rather than screws they use spring lock clips and to join multiple together you have a pin that drops between two. The grounds have a metal bar that rests on the rail rather than the locking screw that these ones use. I think I might get some of these new ones, they look more user friendly. Also have some fuse holder ones also.

The exposed end should always get a blocking card. Terminal block systems are not designed for the earthing block to provide covering for a live adjacent open terminal block. The covers snap in place so if the terminals work themselves apart and form a gap, the card moves with the terminal block and the contacts are always covered and protected. Also as well, earthing blocks should never be used as endstops. It should go earthing block, end-stop, blocking card, terminal block, terminal block,.....,end-stop.

The worst thing you can ever strike is that useless G-profile DIN Rail, that was a thing in the 1980's. It was used in factories and try as you might to remove the terminals from the rail (with the supply still live) without snapping the bottom plastic clamp off, rendering it useless. Top Hat is the way to go.

Linking them together to join more wires isn't there a danger you will exceed the 25amps rating?
@Marcel_Germann4 жыл бұрын
Nope. The whole circuit is fused with 25A at maximum. In case of 2.5mm² wiring I would rather recommend fusing it with 20A. You'll have to ensure that the incoming wire is fused properly. It doesn't matter how many wires there are, they can all not draw more than 25A if the whole circuit is fused with 25A. The overcurrent protection will prevent this.

They would be typically be used in an industrial setting, so everything connected has a known rated current and will likely be fused. So not a problem assuming it's designed correctly.

If you create a circuit you'll have to design it that way that the fuse/MCB rating depends on the weakest link of the chain. Let's say I design a german outlet circuit. Wiring is 2.5mm², under best circumstances it's rated for 25A, normally 20A. Connectors in junction boxes, let's say Wago 221, are rated for 32A. The outlets are rated for 16A, so the circuit is fused with 16A at max (circuit breaker B16A). No matter how many outlets are connected to this circuit. In rooms like living rooms or bedrooms one 16A circuit covers all outlets (and could supply the lighting too without any kind of trouble), and that's sufficient because there are normally no appliances with a high demand. In the kitchen you require several circuits, mostly dedicated circuits with only one outlet for one specific appliance like a refridgerator or a dish washer. The thing is not about demand, you can also hook up the dish washer and the refridgerator on the same circuit, but if you require to switch-off one circuit for whatever reason the other appliance would also have no electric power.
