16A Extension Cord: 1mm2 Wire Thickness Safety & Connecting 35m Series for 15A Load

vodiczka I do not impose anything on anyone. I present my opinion.
What you prefer does not matter because what the user chooses counts.
And he will choose to be lazy because developing the entire extension cord is over-zealous.
And when he reads your posts in this thread, he is convinced that he knows everything because he is infallible.

My Zelmer has less than 5 meters of 2x1.5mm2 cable, so it unfolds practically in its entirety. And the engine power is 1500W max and will not increase as in an extension cord with more than one socket.
It's just to show that the comparison of the extension cord on the drum with a vacuum cleaner is wrong.

As a rule, load a partially unrolled cord only as it is fully coiled in accordance with the warning on the drum, and in the absence of such a warning, unwind it completely.

America's colleague did not discover this "principle". After all, there is no other option but to connect to the extension cord at its end.
There is a colleague for (development) and also against :lol:

Because it's cooled
And there are no cooling extension cords yet.

I checked several times by touching the entire drum with the cable after 30-40 minutes of work and it was always cold, in hot weather only slightly warm (but only minimally). The vacuum cleaner has a power of 1800W.

Don't be kidding yourself. There is no such option as the engine is air and drum cooled it will always warm up even from the air and not from the flow of electricity. This only increases the heat.
And the fact that after 30 minutes it is cold, put it between fairy tales and do not tell them here.

Hello.

Well, it's time for tangible evidence.
Construction Katowice, ul. XXX:


In another case, on another construction site, the caretaker decided to get some sleep.
He burned the extension cord completely. Unfortunately, there are no photos

The engine power is 700-900W. Even industrial karchers don't get any more.

But for the cable from the vacuum cleaner I added a 2kW heat gun because a long cable and a solid plug and I will tell you that the cable heats up completely unrolled.

A simple matter, if someone burns down the extension cord, they will learn to develop the next time. Science must cost.

You impose on your friend, even with this entry:

So stop deliberating on warnings because you can't do something like that.
The extension cord must be fully unrolled !!! Always!

It is not the same as saying: "I always develop it to the end and recommend it to others"

You shoot yourself in the knee again because no one has made such a comparison. And if the rolled up extension cord in the vacuum cleaner does not heat up (which, along with others, I do not believe), it means that its cross section is matched to the engine power so that it can work when rolled up.

First, you need to calculate the resistance of your extension cord

Rolled up and unfolded are identical, the amount of heat released is the same. What will tell us that we lose, for example, 28W of power on an extension cord? The decisive factor is the greater ability to give up / dissipate heat in the unfolded state.

And stick to that

You try to impose your opinion again When the extension cord has the specified current carrying capacity in the rolled up and unfolded state, I use this information, just as I do not drive in the city constantly at a speed of 50 km / h when the road sign allows 70 km / h on a given section.
That is why God gave reason (and the PRL eliminated illiteracy) to use it.

We close the topic because the author has not spoken for 5 days. If colleagues interested in the discussion, we transfer to electricians.
