How to assemble an AC solar safety box to NF standards?

Why an NF-standard safety box?
For me, there's no saving to be made on safety components because it's probably the most important part of your electrical installation. On one hand, it's connected to outdoor solar panels that can potentially be struck by lightning, and it directly connects to your electrical panel, in almost direct contact with your power outlets.
Even if components that seem identical at a lower price might give you the impression of similar safety, having the NF label is a must. If it had no value, everyone would pass the certification easily.
This is not the case, especially with all the products coming from the other side of the world with a CE sticker placed at the border as proof of good intentions.
Your installation will likely be under tension 24 hours a day for the next 20 years, and what works today at half the price might not be the case in 10 years. The problem is knowing how it will fail, hopefully not by catching fire.
So, I decided here to choose only components with NF certification. Other manufacturers like ABB, Siemens, or Hager also offer solutions that meet this standard.
What is the maximum acceptable power for this AC safety box?
I settled for a safety box capable of supporting 3000 watts, which is the basis for all solar self-consumption kits. Of course, you will need to size the cables differently if you need more power.
Normally, if you follow the different steps in this video, your installation will be able to pass the Consuel without any problem.
What does the NF-standard safety box contain?
2 x Legrand C20 circuit breakers to protect the surge protector and micro inverters. amzn.to/3X0PpZF
1 x T2/T3 type surge protector. amzn.to/4dXF4UD
1 x "high sensitivity" differential switch amzn.to/3KmQcN6 (It can be a standard model if the installation is already protected by an Enphase Q-Relay amzn.to/3yNpBpP).
1 x connection comb. amzn.to/3X2WGse
1 x kit comb to differential switch. amzn.to/4e2mris
Optional in the video, you see:
1 x DIN earth connection bar amzn.to/3Vl378E
Tools required:
In addition to a cutter, a Phillips screwdriver, and a wire cutter,
I recommend these crimping pliers for the terminals that accept 16mm², and there are even terminals included! amzn.to/4bEYGuY
Which box to create your safety box?
If your installation does not require 16mm² connections, the first box I tested is this Debflex version with 8 rows. amzn.to/4c1FYO9
It shows its limits quite quickly, and it is probably better to start with a larger model like this one. amzn.to/4bDHypF
This will allow you to place your Q-Relays as well as an electrical outlet for your control center and other current/voltage meters.
To go further:
Feel free to contact me to express your disagreement or congratulate the content of this article.
I do not cover here the part connecting to the main electrical panel, which must be done with caution by adding a circuit breaker directly to the wires coming from your Linky meter.
There is also a step that involves placing stickers on the different parts of your installation when it is connected to photovoltaic panels.
Documents from Siemens remain the property of Siemens, of course.
I have no special ties with the Legrand brand and paid for all the components of my electrical panel myself.
