Then explain what the problem is with powering the alarm from the residual current device for outdoor electricity?P Peter787 said:
It's only a problem if you ignore that the alarm both sends an alert for power failure, keeps beeping for power failure, and then ignores that it sends an alert for low battery voltage as well.
So sure, if the customer/guard totally ignores incoming alarms, it's better to power the central from the residual current device for indoor electricity. But I would say that you probably don't even want the burglar alarm at all if you ignore it when it alerts
Ok. When you mention the 60s, it's interesting.Demmpa said:
The area was built in the early 70s. When I checked ads for apartments in the area, some had those typical 2 outlets but with a 70s design (not new).
They must have started building from the house I lived in and then continued from there, but at that time changed the design of the outlets.
We should almost start our own thread with pictures of different designs through the ages 🤔
Could it be that the outlets were considered unsafe? Since they lacked the "socket well".
I described that in post #50.S SueCia said:Then explain what the problem is with powering the alarm from the circuit breaker for outdoor electricity?
It's only a problem if you ignore that the alarm both sends alerts for network failure, beeps for network failure, and then ignore that it sends alerts for low battery voltage as well.
So sure, if the customer/security guard completely ignores incoming alarms, it's better to power the central unit from the circuit breaker for indoor electricity. But I would say that you probably don't even want the burglar alarm at all if you ignore it when it alarms![]()
You might as well put the alarm central outdoors with your reasoning.
Your solution is not even alarm class 1.
What do you think the security guard who responds does if there's no power to the alarm central?
My guess is: checks the fuse and notes that the power has disappeared and records in the log that it's a power outage at the customer's, i.e., not the alarm provider's responsibility, and asks the central to contact the customer who is on a long-stay vacation in Spain...

I'm neither an electrical firm nor friends with anyone. But that's what I immediately thought of; I wasn't as sure about the other mistakes. However, even I could see that the installation looks unprofessional at several points. It's frustrating dealing with craftsmen who lack both skills and aesthetic consideration and still charge money. Imagine if everyone followed the cable clamp school or knew how to lay pipes without risking lasting impressions on the observer.S stefan57 said:

And this is the consequence of the Swedish way of placing meter cabinets and main fuses outdoors. It was (perhaps) justified when a meter reader came to note the meter reading. But today, all readings are done wirelessly, and the meter cabinet would be better placed indoors. And it would look nicer.Demmpa said:

I had a new central installed yesterday and I'm wondering if this installation is okay? I guess I should put some cabinet or something over it but want to first ensure that this is correct.
I'm personally a bit surprised by the placement but don't know myself if it's safe or not in terms of electrical safety
Why have you placed the HB at the bottom? It doesn't look good.Demmpa said:
I would have chosen a central unit with 26 module widths and 3 or 4 rows, so that the entire hole in the wall would be covered and there would be room left for future expansion.
It would also have been possible to make the central unit more clearly arranged in terms of which RCD covers what.
The surge protector loses some of its effectiveness when protected and unprotected conductors run alongside each other.
This is what our distribution board looks like after replacing an overcrowded diazed central unit and an external standard central unit.

I have left a three-phase spot free on each row before the single-phase groups begin.
The circuit breakers down to the right are extra/spares.
We have our surge protectors out in the meter cabinet

Those were straight answers, thank you. I always install a PSA but was completely sure the requirement only concerned overcurrent protection. I can understand the rule when it concerns multiple charging stations, but not if it's a central in, for example, the garage supplying other circuits with the same RCD. Strange rule.G GoGetLost said:No, it should not share an RCD. It should have its own.
"Each connection point must be individually protected by an RCD with a maximum of 30 mA, according to the Electrical Installation Regulations SS 4364000 section 722.531.2.101. This means that you cannot use an RCD that protects other parts of the facility to also cover the charging station. The type of existing RCD does not matter."

12 years in the game and you don't know that the alarm central should be within the alarmed area? ...P Peter787 said:I described that in post #50.

I've said all along that I can see advantages to having the power supply on the GFCI for outdoor electricity, not that I do so; are you choosing to misinterpret?
If you can't see an advantage in having an alert in a house if the outdoor lighting isn't working, then you're not particularly aware of which protective measures are most effective in preventing break-ins
Our guards check GFCIs, fuses, etc. If they can't reset the alarm, they call the customer.

I've always said that I can see the advantages of having the power supply on GFCI for outdoor electricity, not that I do it, are you choosing to misinterpret?
If you can't see the benefit of getting an alert in a villa if the outdoor lighting doesn't work, then you're not particularly knowledgeable about which protective measures are most effective at preventing burglary
Our security guards check the ground fault circuit interrupter, fuses, etc. If they can't reset the alarm, they call the customer.
I see no benefit in continuing this discussion with you.

Where does this quote come from? It does not say so in the electrical installation regulations. The requirement is that each charging station (=electric car) should have its own RCD if it is of type A or F. There are no other requirements. The text in today's regulations is a bit hastily written.G GoGetLost said:No, it should not share an RCD. It should have its own.
"Each connection point must be individually protected by a residual current device of max 30 mA, according to the Electrical Installation Regulations SS 4364000 point 722.531.2.101. This means that you cannot use an RCD that protects other parts of the installation to also include the charging box. The type of existing RCD doesn't matter."
Each connection point for alternating current shall be individually protected by an RCD with a rated residual operating current not exceeding 30 mA.
NOTE - This requirement means that this RCD is not used to protect other connection points or power-consuming equipment.
Notes in the regulations are not requirements; they are information. You should, of course, consider them anyway.
There are no technical obstacles to allowing an RCD of type A to share a charging station (with one socket) and lighting and sockets in e.g., the garage. An extra RCD might be appropriate, but I would report anyone who forces a customer to bear the extra cost of an RCD for fraud!
Nor is there any requirement for its own overcurrent protection. There are, however, a couple of conditions to meet. It's appropriate to have its own fuse, but as mentioned, it's not mandatory if things are tight and there's an existing protection that can be used.
But good grief...😮 Among the worst I've seen. Could hardly have been done by an authorized electrician?SoderD said:

He he no _definitely_ not okay, that just needs to be redone completely. Guaranteed not an electrician who did it. If it is an electrician, it just needs to be reported, prison for such work.SoderD said:
However, we haven't seen the other 1000 electrical panel installations that were done well at the same time as this one...RoTe said:
