"Le PROMETTANT a fait établir un état de celle-ci par la société XXX DIAGNOSTIC, susnommée répondant aux critères de l’article L 271-6 du Code de la construction et de l'habitation, le 26 mai 2019, annexé.
Les conclusions sont les suivantes :
" L'installation intérieure d'électricité comporte une ou des anomalies.
Anomalies avérées selon les domaines suivants :
x L'appareil général de commande et de protection et de son accessibilité.
x dispositif de protection différentiel à l'origine de l'installation / prise de terre et installation de mise à la tere.
x La liaison équipotentielle et installation électrique adaptes aux conditions particulières des locaux contenant une douche ou une baignoire.
x Matériels électriques présentant des risques de contacts directs avec des éléments sous tension - Protection mécanique des conducteurs.
x Matériels électriques vétustes, inadptés à l'usage."
Yes, it's spelt "mise à la tere" here, sad to say.
My stab at this is "installation's entry point". Would be nice to hear from an LX specialist (you know who you are, Tony ...).

at the input to the installation
Or even 'on the incoming feed to...' — but I think 'input to...' is better.
The point is, the differential circuit breaker is the boundary between the supply utility's feed and the subscriber's own installation, and thus it is from this point onwards (only) that the surveyor is concerned. Their interest here is usually that the sensitivity of the ELCB (as we used to call them!), whilst perfectly usual, is not atched by the resistance to earth of the installation that follows it.
I have this exact-same problem in my own house!

Thanks, Phil! I'm afraid I can't agree, on technical grounds: 'entry point' sounds more like where the cable physically enters the building, which may not necessarily be the same point we are concerned with here.

A distribution board (also known as panelboard, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure. Normally, a main switch, and in recent boards, one or more residual-current devices (RCD) or residual current breakers with overcurrent protection (RCBO), are also incorporated.

Note : le terme « dispositif de protection différentiel » n’est pas approprié pour une DDR. Il désigne un dispositif industriel protégeant les générateurs, le réseau de distribution et les transformateurs associés :
Une protection différentielle est une protection électrique qui consiste à comparer le courant entrant et le courant sortant d'un appareil. Si les deux sont différents, la protection conclut à une fuite à l'intérieur de l'appareil et commande son retrait du réseau électrique, on parle de « déclenchement ». La protection différentielle est une protection très répandue. Elle sert à protéger en particulier les jeux de barres, les générateurs et les transformateurs.

A residual-current device (RCD), residual-current circuit breaker (RCCB), or ground-fault circuit interrupter (GFCI) is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.

RCDs operate by measuring the current balance between two conductors using a differential current transformer. This measures the difference between current flowing through the live conductor and that returning through the neutral conductor. If these do not sum to zero, there is a leakage of current to somewhere else (to earth/ground or to another circuit), and the device will open its contacts.

Yes, Google hits can mislead us as they can come from different areas. But when there are so few hits for a suggested phrase, then this problem of fields does not exist as there aren't any!!! You have to draw some other conclusion then
How can you say to someone?
"As I said before, this is not really idiomatic in EN, and many examples actually derive from too-literally translated sources."
based on the ghit figures as "at the origin of (the) installation" scores in the millions, albeit with this problem of field.
Regarding your comment about my own answer, I don't know where you get your "1 Ghit" from — when I searched, I got over 3 million! It does depend a bit how your group the phrase, as some phrases are too specific, or the syntax is too particular to yield many results. You do also have to bear in mind the context in which an expression occurs... there's nothing to say that certain expressions cannot exist, and can have an undoubtedly similar meaning — but it takes deeper research + specialist knowlegde to check thoroughly that the contexts are comparable, and it is then you get a wider picture of how the expressions are used and are able to see if the contexts match.

"Entry point" gets a lot of hits too but not always in the right field. But it still beats the 1 ghit above. Yet it gets treated as "sloppy" and "poetic licence". To that my reply is at least it's English
See:
"entry point to the installation" About 657.000 results (1,00 seconds)
Why you did not propose this?
A point of method not open to any negotiation / discussion.
In correct technical parlance, we would never say 'the electricity enters the installation via...'
It is important not to be sloppy in the use of what are after all technically-precise terms, especially in a document of this contractual importance!
This is the point at which the power connection comes INTO the installation — it is the input.
It's very important not to get sidetracked by wider issues that are irrelevant to this context. We might be talking about 'incoming supply feed' etc. etc.
For this specific context, we are talking about the boundary point at which the particular installation under consideration starts: think of the installation as iof it were (say) a hifi — when discussing the hifi, we could refer to its 'input' as being the starting-point for consideration. Looked at from another angle (not helpful here!), we might equally talk about it as being the 'output feeding the amp' from somewhere else...

This document is very clearly a 'diagnostique technique', again, a very common document these days, a kind of cursory 'survey' that is obligatory when a house is sold; this is pretty much boiler-plate wording, so we can tell that this is a residential property, typically with a 15 / 30 / 45 A circuit-breaker with 500 mA differential; in itself, this belongs to the supply utility, so is not part of the survey, except (as here) inasmuch as the downstream wiring is not consistent with its ratings.
