What cross-section of the wire for a clinker with a 50W bulb?

Question

Hello I would like to know if a wire with a cross-section of 0.5mm2 is sufficient to power a clinker with a 50W bulb? Regards

It is not used in installations with a cross-section smaller than 1.5mm2 ... What do you want to use to protect a circuit made with a cross-section of 0.5 sure B10A or more :D Power supply and security probably went into the forest.

You must be joking here, there is nothing to think about, what kind of cable do you want to give, probably YTYKSY to which the mains voltage cannot be applied. I do not want to believe that it will not fit in YDYp 3x1.5 plaster

If the diameter is can and catches the cross-section of 1.5mm2, however, it should be 0.5 fi not mm2 ;) There is also something like protection, receiver power is not everything that must be provided SWZ and I suspect that on such small cross-sections IPZ will not be within tolerance ;) You don't need standards for this quote from the manufacturer's website: Notes: The cables cannot be used in power installations. The peak value of the cable's operating voltage must not exceed 50V AC and 75V DC. Bitner, in turn, quotes: Rms value of operating voltage V

It is enough, which does not change the fact that it is better to give more than regret later that we gave too little. It's not better to give 1.5mm? and have peace of mind.

The problem is that the clinker will hang on the reinforced concrete wall and I will have to cut a groove in it for this cable to the box, the thinner the cable, the more convenient it will be to cut the hole, but I will think about it. Thanks for the help

adar0 · Answer

You're right, I've read a bit just now and I'll give YDYp 3x1.5. Really, thanks for your help. I would have made a huge mistake

Piotr2608 · Answer

Now answer two more questions: - what kind of installation do you have at home? Aluminum or copper? - where do you want to plug the power cords into this wall lamp?

If you don't know what he wrote wrong, I'll tell you. He wrote that a 0.5mm? wire is enough.

Piotr2608 · Answer

I knew what I wrote. The precise question was whether a 0.5 mm/2 cable would suffice for a 50 W load? A wire with a cross-section of 0.5mm/2 has a load capacity of 6A, which gives us about 1200W. The author did not specify how he would make the connection - he could do it using a night lamp. Everything was fine until the issue of the cable installation was explained in further posts. The author wrote: The problem is that the clinker will hang on the reinforced concrete wall and I will have to cut a groove in it for this cable, the thinner the cable, the more convenient it will be to cut the hole, but I will think again. Thanks for your help And here the rules played on everyone's nose. Intervention on my part turned out to be unfounded because my colleague mawerix123 explained the topic to the author. Now that the topic would be closed after my answer - I understand the philosophy and the way of conveying the information as well as its interpretation would be harmful. Of course, the point of view depends on the point of sitting. Developing the topic of plugging anything into an electrical outlet. Well, this does not apply to generally available power cords. The vacuum cleaner with a load of 2000W uses 0.75mm/2 wires to power audio equipment. Power cords of the eight type approved for sale in the territory of the Republic of Poland - length 5m, diameter 0.5mm/2, often used to power Audio amplifiers with a current consumption higher than the author's bulb. For electrical installations inside buildings, insulated wires are used for permanent installation, called installation wires. Common installation cables are manufactured for rated voltages of 300/300 V, 300/500 V, 450/750 V, 600/1000 V and have copper or aluminum conductors with cross-sections in the range of 0.5-300 mm?. There is no standard prohibiting the use of 0.5 mm/2 wire in the wall. The relevant standards only regulate the thickness of the conductor to the load, the thickness of the conductors in the ground. Fellow moderators either don't know the rules or misinterpret them. Secondly, as I believe, most electricians use 3x1.5mm/2 wires with a real cross-section of 1.1-1.2 mm/2 calculated from the new cross-sectional formula to save costs and increase profits. Such cables allowed by Polish law are generally sold on the territory of the Republic of Poland.

There is information in #1 of the author of the topic. Sconces usually hang on the wall and not on the dresser

Piotr2608 · Answer

Read the legal standards or show me one that will prohibit me from using the YTDY 2x0.5mm cable
in the wall. If no one has indicated such a standard by Monday, the case will go to the arbitration court.

The cross-section of the cable has been selected with an appropriate excess to the mounted load. Secondly, in the era of lights and LED lights, why not immediately install 3x10mm/2 wires.

Do you realize that you may have ordered a 3-core cable to be connected to a 2-core installation, and even worse, to an aluminum one?

Piotr2608 · Answer

I read and did not find it, but apart from the topic, is it written somewhere that the wall lamp will be powered by 230V? You are not there. Maybe it will be connected to a 12/24V low voltage system using a transformer or step-down power supply.

Example:

http://www.skapiec.pl/site/cat/2953/comp/12619388

I understand "trash" but a warning for 365 days? If this warning belongs to the Administrators group. When creating a topic, the author should answer a few questions, such as: what kind of installation are we dealing with (12/24V lighting installations are becoming more and more common), what electrical protection do we have at home, what type of network is used in the building/apartment, how do we want to install ... cable, receiver, with what load/power.

And so we would have:
- 230V installation
- let's say a 10A fuse
- 2-wire network system (I do not require a layman to recognize the type of network)
- wall mounting
- 50W bulb

We know everything, no guesswork and clear as day.

Give this shop a warning too, because a layman does not know what he is doing.

mawerix123 · Answer

Have mercy on what else you come up with. The layman asked if he could use it to make installation wire with a cross-section of 0.5 mm2, the answer is one CANNOT use such a wire. You can't suggest doing a botch. It was necessary to ask before answering, not to foam now.

Piotr2608 · Answer

I invent? It's you who invent. And did you give him the cable laying zone according to the standard? I don't invent anything, I drag the subject, I draw unknowns like in mathematics - an equation with two unknowns or worse, a canonical equation :) Added after 3 [minutes]: No. The Polish teacher always taught me to answer the question precisely and concisely. In the RTV department, they knew how to force the authors of the topic to answer questions about the purchase of a TV set. The question asked was precise as was the answer to it.

CYRUS2 · Answer

Only a complete amateur without knowledge claims that wires are laid in the ground. He can't even understand the rules. Too high a bar. Amateurs - you can't lay wires in the ground. With your level of knowledge, you compromise the service company in your profile. Ps. Red moderator entries are not deleted. No comment.

mawerix123 · Answer

No, I did not specify how to cut the plaster, forge the excavated material, fasten the cable, turn off the circuit, insert and connect in the junction box, make the necessary measurements after the installation, hang the wall lamp, screw in the light bulb, turn on the voltage, press the switch key, check whether lights, write out the protocol and invoice and why because there was no such question. You shouldn't have answered if you didn't understand something :) PS: I am not trying to repair electronics and household appliances .... why because I don't know about it ;) For me, the topic is exhausted. Regards.

Piotr2608 · Answer

Start reading with understanding electrician for 3 pennies. First, to be able to lay the cable in the ground, you need to calculate the diameter of the cable according to the load - PN-E/76-05125 and PN-E/98-04700

kozi966 · Answer

Dear friend, you would receive another warning for such a statement. This statement contradicts what is written in the PN-IEC 60364-5-52:2002 standard in table 52J. In fixed installations (such as the wall lamp power supply installation), wires with a minimum cross-section of 1.5 mm2 should be used for lighting / power circuits. And the supply voltage doesn't matter here. Flexible connection circuits (connections and not for permanent installation), for SELV, PELV voltage, must be made with wires with a cross-section of at least 0.75 mm2.

What cross-section of the wire for a clinker with a 50W bulb?
