But now I'm curious about THAT explanation...
Why is a separate RCD necessary for the computers? Normally the computer just sits somewhere, plugged into a regular outlet,... does the hairdryer and toaster also each get their own RCD? I just don't understand that. And why does the required space in the control cabinet increase so drastically with 15 additional outlets? As said, either it was completely planned wrong from the start, or it's a rip-off.
Regarding CAT without conduit in the wall: I'm also curious why anyone would do that
And there's absolutely nothing against good power strips and proper use. Visually, many want to avoid that as much as possible in new buildings, but that’s purely a visual matter.
Here I attached his explanation for you. It sounded logical to me, my husband was skeptical though.
I also don’t know why a separate RCD for the computer should be necessary, but he insists on it vehemently.
I also find the thing with the outlets strange. That would mean the control cabinet was already planned 100% full beforehand, which somehow can’t be right. But I'm not an expert. :/
Sorry, but why CAT cables without conduit in the wall? Total nonsense.
And you can measure even without a patch panel.
Certainly, you won't get a certified report either.
For 600€ you get a Metz patch panel including keystone modules and still have money left.
Is the panel supposed to go into the office too? Like with a small server cabinet or something?
No, the panel and switch should also be in the utility room. It seemed way too expensive to me as well, we definitely will not accept that offer. I don’t trust it either, but since we want to live in the house for the next 30 years we somehow have to sort out now what we really need (for us), and where the electrician is trying to make a few extra euros.
Of course a PC does not need its own supply line, but the stove and the e-car charging station do. Generally, a power strip is not a good solution. That should always be avoided. The number of outlets doesn’t matter physically. You just have to know that you can draw a maximum current per circuit. A standard fuse is 10A. So I can only "draw" 10A. That can be 10 x 1A or 2 x 5A etc. My PC (please don’t get upset!!!! video PC) draws nearly 1kW.
To explain: 240 volts x 1 ampere = 240 watts.
And btw: There can be no fire risk with a properly installed system. The built-in protective mechanisms reliably prevent that!!!
That’s where my knowledge runs out. Can we still operate both our computers on one circuit, and at the same time have the fridge, freezer, and so on running – basically our household is like other normal people’s, just that we have 2 gaming computers.
I can’t imagine the extra cost being necessary, since we currently rent a 30-year-old house, with a 30-year-old (single) circuit and only one RCD, and everything always works perfectly here.
for 600 € you can get
19" wall cabinet, 8-12U: 100€ (basic) up to 220€ (better)
MetzConnect modular patch panel including 24 keystone modules: 180 Euro
Zyxel 24 port gigabit managed switch: 130 €
a handful of CAT6a / PIMF patch cables in colors with Hirose connectors
and whoever buys all that cheap can also squeeze in 2 hours of installation time
within the 600 €
So if the electrician bangs the CAT cables into the wall without the required protective conduit, he should later pick them back out and lick up the dirt from the floor
I don’t like that either. How do I get them to do it properly without getting into a fight with them? I also don’t want trouble with them, I fear they’ll mess things up if I act too much like the nagging customer. :/
There must be a main circuit breaker before the meter in the house, i.e. the main fuses. Also, a fire protection switch is required (must) in a wooden house. With photovoltaics, a surge protector must be installed. Then at least 2 RCDs. And extra space for expansions (e-car), additional breakers, energy management, possibly actuators or a timer... Sure, a PC has 700W. Have you ever measured what it actually needs? What is your current yearly kWh consumption? 700W is not always the input power, sometimes it’s the output. A normal office PC doesn’t draw more than 40W (thanks to SSD and Intel power management). I currently have a few ESXi servers for virtual desktops at work, each with 2x1.6kW, but the Tesla GPUs are really intense under continuous load...
Back to the topic: why more outlets = more space in the cabinet I can’t understand. The cables don’t run together in star formation, nor are groups realized. In our case, each room has its own supply line with its own fuse. Then the stove separately... But that’s basically a matter for the general contractor and electrician. We didn’t have to pay anything extra for the larger cabinet etc.
So far we have purchased about 4000 kWh per year. He wanted to charge us for the 2nd RCD as well, but the general contractor is now clarifying that.
