I would like to know if it is fire protection technology to combine an extension cable (coming from a wall socket) with a multiple socket and then to supply power to the multiple socket, laptop, TV, router, sewing machine and desk lamp? However, everything would not always run at the same time, except for the router (24/7). Example: When I'm working on the laptop, I may still have the lamp on. The rest were on standby. It is the same for the sewing machine in combination with the lamp.
Basically, this would be possible without problems if the extension and the multiple socket were built with cables with a cross-section of at least 1.5mm². Because such cables are able to safely carry the current that the 16A fuse in the fuse box allows without switching off, without anything becoming too hot. However, there's a special regulation that allows the connection line of multiple sockets or the extension to be made with thinner wire if these are not longer than 1.5m. That's why it says everywhere that you can't put them one behind the other. The parts with the thicker cable are more expensive because there's more copper in them. If you want to be sure, get those components.
No problem, as long as the total 'consumption' (power consumption) of the connected devices does not exceed ~ 3750 watts. So two hobs with 2000W each would not work, but the devices you mentioned are all 'small consumers'.
That's fine.
This is very difficult for me to understand, I have 0.0 knowledge of electrics. So the thicker the extension cord the better? My multiple socket has exactly a cable length of 1.5 meters.
Even a laptop counts as a small consumer? And even with a sewing machine I would never have thought that.
You should refresh your half-knowledge a little by reading DIN VDE 0100, because that is only permitted under "conditions".
That may work, but fire insurance will have its own opinion in the event of an emergency.
If you look closely at the cables, you will find a label that tells you whether the cable is 1.5mm² or 0.75mm². If both cables have 1.5mm² everything is fine.
Your half knowledge
Says the hairdresser to the electrician.
I don't find any of this information. The extension cable has the information: 16/250, 1561 AP, FI, N, S, Vde, acras 937-X 16/250
On the other extension cable I could still choose: 3680 W, DG - YDB0I, 16A / 250 V, YP03, 1766AP
The multiple socket gives the information: 250V - 50Hz, 16 A, max.3600W
This man is not talking about the cross section of the cable, the length of the cable!
A bad electrician is still a very good hairdresser
I found it now, the writing was barely recognizable, both have 1.5 mm²
I understood that then, but unfortunately I couldn't find the label and as a layperson it is a bit confused
Then everything fits!
Dear WillEsWissen64,
if I were a hairdresser, I would keep my mouth shut when it came to safety-related questions regarding electrical equipment and fire protection and would be silent. As a lecturer for hardware and software development and operator of a computer repair service, you are completely familiar with the regulations for the protection of power supply lines according to DIN VDE 0100 T430 and the associated special and exception rules, because this knowledge is essential for writing software, circuit boards to develop and replace defective computer plug-in cards with new ones. Although you don't even do it practically, you only teach about it.
Shoemaker stay with your lasts and in the future only comment on topics that you really have a clue about, because apparently you have never read the regulations relevant to answering this question in your life, otherwise you would know why most of the multiple sockets sold in Germany are not permitted for cascading. I hope for the benefit of your audience that your knowledge of software and hardware development is more solid. Fortunately, the fire risks are significantly lower in this note. But please refrain from writing software for nuclear power plants or self-driving cars.
As for your comparison of bad electricians and good hairdressers, I can only say that a bad hairdresser at the shop door is waiting for the hair of the clientele to grow back to try again, but a bad electrician is waiting at the cemetery gate for the mourners comes out again.
Sewing machine under 100W, laptop 45W, computer 400W, vacuum cleaner according to EU specifications up to 600W, (formerly 1600W), coffee machine 1000W, iron 2000W, air conditioning 2300W, fan 60W.
Everything that heats or cools (which also works with heat) is rather critical, what only moves is rather uncritical.
Laptop, TV, router, sewing machine and desk lamp
And what kind of scaremongering is done here because about 500W end consumers are to be operated on a household extension with a multiple socket… How incomprehensible is that and how disproportionate.
First, please consider that you are giving advice to total laypeople. You take responsibility. And the sewing machine in particular is a potential source of overload, because it is most likely that a series motor is built into it, otherwise the pedal would not be so easy to construct. And this is exactly where the protection of the lines against overload by the upstream line protection is essential to prevent fires. It is therefore essential to use components that are matched to this (16A) back-up fuse.
You should first think a little and maybe even think about what if before you risk another user losing their home due to an avoidable fire due to your "good advice".
