    Hello!

    Which cable should be used to connect the LED as shown in the diagram below? I bought an 8x0.5mm (intercom) 8-core cable, but will it be ok?

    How will it be ok? I am interested in a 6-wire cable so that I could lead it out of the lamp in one cable. There is something like that ??

    I found something like this: YLYS: 6x0.6 + 1x1; 6x1 + 1x1.5; 7x0.75; 7x1; 7x1.5, YLYS 7 x 0.75 + 1 x 1 mm
    LIYY 6x0.75

    which will be the right one ??

    From what I have read, the cross-section of 0.5 mm2 will probably be ok. Please confirm, or so?

    kkas12. You are a moderator, so explain why it will not be appropriate? Isolation breakdown voltage or maybe the conductor cross-section is too small?

    Only that the cores of this 8x0.5 (intercom) cable are most likely 0.5 mm in diameter and not 0.5 mm2 in cross-section. In telecommunications cables, the diameter of the conductor is given, not the cross-section (I don't know if all of them). You will have a cross-section of less than 0.2 mm2 per wire. I don't know what the moderator means but he has to endure it. The only obstacle may be the voltage drop if the distance between the controller and the lamp is long.

    Even 0.2mm2 has a load capacity several times greater than 350mA. I do not have a table at hand, but I do not like the answer. "No.
    It won't be ok. "Without explaining why?

    So find out what the minimum cross-sectional area for wiring in electrical installations is and stop spamming. Do you have to give lectures every week?

    It should be added that this applies to permanent installations. If he gives the driver in the lamp, it will be ok.

    retrofood. Read this http://perunwit.w.interiowo.pl/obcp.html. So according to you to install an infrared camera there should be a cable. What? This table is at hand.

    What does that have to do with this topic because I don't understand?
    The lighting installation is not a camera.
    Helpful post? Buy me a coffee.

    There are also lighting diodes. (Infrared). I power them via twisted-pair. To finish it.

    But which one will be ok? Ten 8x0.5 mm?
    I found two such cables: LIYY 6x0.5mm2 or
    LIYY 6x0.75mm2
    Will they be ok to connect the entire layout? I will add that the controller will be outside the lamp at a distance of about 1m. I can not find wires with such a cross-section, but there should be a wire in a single strand. Are they like that?

    Will someone answer? Which of the above cables should I buy? 0.75 mm2 is it enough 0.5 mm2?

    A power supply with "efficiency" 4A and a cable with a diameter of about 0.2mm.
    What else to translate ???

    A cross-section (minimum) of cables used in installations is a requirement, while the choice of luminaires and light sources is a "fad" (often depending on the current fashion) having nothing to do with the requirement.

    A power plant with a "capacity" of 20GW (example) and I have stupid wires in my apartment "only" 1.5mm2 and 2.5mm5. Maybe instead of getting smart, you would write something specific? More is required of a moderator than a regular user.

    You really have to be dumb to get hard on the power plant.

    You didn't understand the sarcasm. You probably don't know what the difference between LEGO bricks and sex is. Therefore, keep playing with blocks.

    LIYY is 0.5mm2 x6 suitable or not? Do you take 6x 0.7mm2? What diameter is 0.2mm?

    well, I read, but I don't know what to attach my diagram to ...
    according to calculator: Link

    it comes out that 0.5mm2 is enough. how is it? some say that it will be ok and acc. of these tables, I would have to pull the 6x1.5mm2 cable to these LEDs?

    The sum of all currents in the branches will flow in the red wire, so the appropriate wire will be 6x0.5 (individual channels, one wire will be free) + 1x1 (Output V +).

    You are to do installation between the power supply and the light source!
    Installation !!!
    And you are bound by the installation requirements and not the inventions of the ingenious Dobromir under the slogan enough or not enough .

    But we are talking now about the cable from the beginning of the topic, i.e. 8x0.5mm (not the cross-section)? I do not get it 1x1, link two wires for V +?

    And this one will be ok: LIYY is 6x0.5mm2 (cross-section) ??

    edit.

    what about this calculator?

    This is a data transmission cable, not for powering receivers !!!
    And in its declaration of conformity it is written:
    Quote:
    We declare that the products from the batch specified in point 5 are compliant with the reference documents mentioned in point 4
    (including all changes and additions) on condition that they are used in accordance with their intended purpose and with the applicable standards and technical recommendations.

    So please give me a specific model, I'm looking for a whole day ... I'm not an electrician. I will ask again and you can close the topic. What is the best 6-wire (what cross-section?) Cable to buy for a specific diagram from the beginning of the post?

    You insisted on the cable (not the cable, but rather the cable).
    Pull the appropriate number of wires with the correct cross-section into the conduit and you will have the "problem" solved.

    well, what kind of cross-section to use? there is nothing specific on the market? if there are no 6 wires then maybe 3 wires though.

    ps. the lamp is to stand in the living room so the conduits are probably falling off :)

Topic summary

The discussion revolves around the appropriate cable selection for connecting an 8-core LED intercom system, specifically questioning the suitability of an 8x0.5mm cable. Initial responses indicate that the 0.5mm diameter may not correspond to the required cross-sectional area, which is likely less than 0.2mm² per wire. Participants debate the minimum cross-sectional area needed for electrical installations, with suggestions for alternatives like LIYY 6x0.5mm² or LIYY 6x0.75mm² cables. The consensus suggests that while 0.5mm² may suffice for short distances, a larger cross-section is preferable for reliability, especially in permanent installations. The conversation highlights the importance of understanding cable specifications and installation requirements.
