Hi, can any one please advise me. I have bought most of my electrical stuff at Bricodepot. All my RCD's are Debflex and so are my breakers. (Disjoncteur's) My question is. How do bridge from the RCD to the breaker. (Disjoncteur's) Is there some type of barres that you can use. Or do you just bridge it with 6mm cable. I have been told this with not pass the consuel. I have asked this question in Bricodepot and received no answer. I have seen a type of bridge in Leroy Merlin, and bought it. But these will not fit Debflex. Thanks in anticipation for your help.

Never used Debflex, but the peignes de raccordement of Legrand are rather universal. See also this recent topic. RA

I am not an expert by any means, but not sure about what you were told that a cable bridge is not acceptable. One of the experts will confirm this when they log on!

I confess to using Deblex in my pool room and out house. They are a nuisance in that on their IDs the connectors are on the same line so that one cannot even use a 'bottom in' and top out using the universal barre to the MCBs. I used 'top in' and bottom out' using 10mm cable carefully bent to go behind the ID and up into the first MCB and then a barre across the five additional MCBs.

Nowhere as neat as Legrand programme, but nowhere near the price either!

On the odd occasion that I have had to use this method, I would use 10mm or higher. This method has never failed a Consuel inspection for me.

Hal, sunday, confession time, accepted. But please use Legrand, Hager, Schneider and other quality equipment. These peignes de raccordement make life easier, and prevent anyone from making wiring faults or using underdimensioned wiring: simple. But as far as I know, these peignes are not obligatoire, just searched the French electrical code, perhaps overlooking something, please let me know, so my understanding is that both methods are allowed.

Robert - yes, on my main house, it is all Legrand, latest stuff with all the up/down and across barres, a real work of art, in fact I have not even screwed the coffret covers on yet as I take them off so often to show my visiting mates who reckon to knowing a thing or two about building, how far ahead the French are in consumer units! Never fails to get admiration!

But the budget starts to run out and suddenly Debflex MCBs at 3.90€ take on a different beauty! I will change them maybe when funds build up again.

I missed the OPs 6mm request, yes it should be 10+ according to my electrician and confirmed by Le Dolly. It is all very well to say that the peignes and barres overcome undersized wiring, yes they do, but until everyone makes their devices to a standard, it will never work. Having said that, if I were M. Legrand and just developed a very smart system that does away with wire on all the device feeds in a box, I would be pretty peed off if Debflex suddenly came up with a pattern that would use my design.

I remember seeing for sale in Brico Depot pairs of flexible 10mm busbar leads for connecting the RCD (Inter.Diff.) with the MCB (Disjoncteurs). They have pin crimps on each end....I'm not certain that they will fit Debflex, but worth a looksee.

Usually I stay away from Debflex products, removed them several times, but I don't remember exactly how they look like. I noticed however that on the Debflex website they say the following about their range of disjoncteurs: Adapté pour peigne de raccordement. The same for their interrupteurs différentiel. And in their section "Raccords de modules" they surface once again. Question: is there a "premium" range of Debflex products, or might it be that the bricosheds are selling an older range of Debflex products? Buy now, pay now, surprise later? RA

Legrand reference 404 904 - they can be used as suggested, or I use them to link from DIN rail mounted main switch to the vertical peigne system:

Well done Badger....Those are similar to those I've seen at Brico Depot.
RA....I took out a Debflex ID a couple of weeks back which didn't work, though I did have to replace a Legrand one for the first time ever which also didn't trip when tested.
I just wander....how many people actually test their Inter Diffs?

I continued my search for Debflex documentation, how to bridge from the interrupteur différentiel to the disjoncteurs. Their "Declaration de conformité CE" shows on page three an interesting piece of non-information. Interested in knowing what they prefer, alimentation par le bas ou par le haut, we see under the item: "Method of electrical connection" nothing useful: a grey area. So probably this means: do as you please.

The Debflex ID doesn't allow you to use the standard peignes to make the connection to the disjoncteurs. The connections of this ID are not décalés, the disjoncteurs are.

So using Badgers wires as alimentation par le bas, you'll need two additional short ones for the connection on top to feed the row of disjoncteurs. RA

Hi, thanks for all your reply's. I shall be off this week to look for some of these connection devices. Unfortunately it's the budget thing with me when I came to using Debflex. Such a big difference in price. I have seen Debflex in Leroy Merlin also, and thought they couldn't be too bad. Thanks again to you all.

Bad luck!

On a serious note, you will not fail the Consuel. There are rails for linking from RCD to MCB, but the position of the fittings on these is specific to the manufacturer, so unless you have all ther MCB's of the same make, AND and RCD either the 'parallel' (supply in and out on the top) AND RCD's designed to take rails, do it as you said; 6mm cable.
