Not sure how France has become involved who cares what they do.Read back on the thread. Whole house over-current protection.

Sorry if I side-tracked the chain. I asked just from curiosity.Why on earth are we discussing France?
It looks like he has a user whole house over-current device. The French have them as standard. How others are doing matters is what a good electrician would want to know. We can learn from them.And this helps the OP how?
We are not in France it is irrelevant.It looks like he has a user whole house over-current device. The French have them as standard. How others are doing matters is what a good electrician would want to know. We can learn from them.
Anything electrical is relevant. That is your personal opinion, which I do not subscribe to. As I wrote: "How others are doing matters is what a good electrician would want to know. We can learn from them."We are not in France it is irrelevant.
its a 15th edition board with RCd mai switch feeding another 15th edition board woth RCD main switch, such boards were made redundant due to 'nuisance tripping' hence we ended up with 16th edition boards with main switch and RCD for sockets, As for the French, they dont use CPCs hence all the double pole isolators and RCD main incomers, which at 500mA is enough to kill people which only requires about 50-60mA.It looks like he has a user whole house over-current device.

The French do use CPCs. Every modern circuit has a CPC going back to the earth bar in the CU. The CPC is a parallel N conductor as the cpc and N are connected, as in the UK. The vid showing the insides of the French CU I posted with the Wago type of push fit connections shows the cpc's.its a 15th edition board with RCD main switch feeding another 15th edition board with RCD main switch, such boards were made redundant due to 'nuisance tripping' hence we ended up with 16th edition boards with main switch and RCD for sockets, As for the French, they don't use CPCs hence all the double pole isolators and RCD main incomers, which at 500mA is enough to kill people which only requires about 50-60mA.
Why would I want to when I have a board full of RCBOs? Nice to hear the French have updated to cpcs.Whole house over-current protection. You can actually buy the French main RCBOs in the UK. OR main your own with an RCD and MCB in an enclosure.
Many reasons.Why would I want to when I have a board full of RCBOs? Nice to hear the French have updated to cpcs.

The French are ahead of us. It i worth looking at the best ways. Staying static is no answer.

DNO will still care about their supply system and what's connected to it, they only allow something like 25 amps per house.Many reasons.
1. A main RCBO is a safety net.
2. It protects the system while 30mA RCD/RCBOs protect people.
3. Also it ensures the main fuse will not blow, with an expensive DNO call out, when with all appliances 4. on it will exceed the main fuse's rating.
5. I fitted a whole house main MCB and an S type 100mA RCD in an enclosure in one job as with electric underfloor heating and DHW the 60A supply was pushing it. Diversity said 70A.
6. Looking at the lifestyle of the occupants, diversity usually covers it, but on one instance it may not, then bang, the main fuse is blown.
7. I fitted a Bosch induction hob that operates off a 13A plug.
8. A whole house over-current device will make the DNO not care about diversity as their system is protected, which is all they are concerned about.
