Maximum Power for 16 mm2 Cable Over 8 Meters with 28kW 1-Phase Heaters and Appliances

Question

I warmly welcome :) Please help oriented :) What is the maximum power to load a 16 mm2 cable with a length of 8 meters, assuming that 28 kW are 1F heaters, the rest are common household appliances (washing machine, fridge, kettle, several computers, sockets with devices with low power...

28 kW is the radiator power for sure?

Single or three-phase power supply?

karolq · Answer

I think 2.8 kW, because 28 kW at home is not feasible even on 3 phases Pre-meter protection would have to be 50A! In a 1-phase system, you will not load 16mm ^ 2 to the maximum, because the protection will not give you. I do not know about other power plants, but we have a 1-phase fuse max. 25A. I assume this is copper. As for the maximum load:

This is the total sum of heaters that will work in the room, each of 2000W / 230V 3F power supply, but each radiator has a separate circuit and the phases will be evenly loaded on each of the circuits. YDY 5x16mm2 cable This is an 8 m long section of cable that will connect the meter with the indoor switchgear. WLZ has sufficient stock.

And what security do you have in the building?

Grzegorz_n · Answer

I do not have it yet, in the sense that I will apply for an additional power allocation and depending on how much I will apply, I will have such security. That is why I would like to know how much power I can put on the cable. By the way... I need tables where I can look at the cable cross-section and see what power, what current, etc. or, for example, what protections are used for different power values or the load in A, how many kW. In general, I am interested in a collection of such conversion tables for various electrical applications. Where to look for it?

Specify - here I refer to the author of the topic - the type of stoves you want to power. That is, brand and power.
In addition, you ask for details that you already know well because you have already done a similar installation.

Is it the same?

retrofood · Answer

The author of the topic disregards any comments from experienced electricians. He only asks because he wants to do as he thinks and only looks for acceptance of his ideas. Violates point 11 of the forum regulations, not presenting the whole situation for analysis, but sipping his problems, which makes the posts artificially punched. I close the topic so that someone looking for similar solutions would not be guided by his theories ..
