1400W Mower: Choosing H05RN-F/H05VV-F 1.5mm2 or 2.5mm2 Extension Cord for Optimal 40m Length

Hello

I have a problem with buying a lawn mower extension cord. I bought a 1400W mower.
The instruction manual states that the power cables must be of no lower quality than the H05RN-F or H05VV-F type, with a minimum cross-section of 1.5mm2 and a length of no more than 25m.

The problem is that I need a 40m extension cord. If I buy a cable, e.g. PS-US 3x1.5mm 40m H056VV-F, will I not damage the mower?

On your forum I read that the longer the cable, the more power is lost.
Shouldn't I buy a 2.5mm extension cord, and if so, what kind? 2x2.5 or 3x2.5mm2?
I can't find those 2x2.5 anywhere, and the 3x2.5 ones are extremely expensive and on the drum. I don't know what to do with it anymore

Therefore, any help is appreciated :)

Iwona

Hello, 2 x 1.5 mm is enough, as long as it's not Chinese, best regards.

H05RN-F or H05VV-F designation are rubber insulated cables, recommended due to operating conditions (moisture, frequent coiling). At 1400W, the mower's rated current (without load) is 6A, from this it can be calculated that for a length of 40m the voltage drop is about 5V, in the manual, the operating voltage is usually given in the range of 230V-240V, so this decrease is within this tolerance. the number of wires (plug model) and the working time with one mowing, in a mower with this power now an additional protective conductor is required. Summing up, an extension cord in the H05RN-F or H05VV-F standard 3x1.5mm should be sufficient (budget). If other receivers with higher power are to appear in the future, it is worth investing in 3x2.5mm. You should definitely pay attention to always mow with the cord fully stretched, the fuse should not be smaller than 16A, the residual current device 30mmA.

And if our friend wanted to connect a receiver in protection class 1, what to buy a new one. Because the one that my friend recommended has only 2 veins.
To Mrs. Iwona.
Sockets with protection pin only in the case of an extension cord.
Such an exemplary extension cord.

Why bigger?

To @prpd:
working time with one mowing is about 1.5 hours, with my old mower (1000W).
However, as for the extension cord, I was thinking about something like this:

I just wasn't sure if it shouldn't be 3x2.5mm with this length, just to be on the safe side :)

To @K-rzysztof Reszka:
The extension cord will only be used for the mower. I do not plan to connect anything else to it.

The latter model should be ok.
I would also take this 3x2.5, but seeing the price of it, I cooled down a bit ....

I also tracked down a 3x2.5

and now i'm in a bind :)

Which one to take ??

Ha! I use a similar one myself. the cable is a bit thicker than the previous one (this cable has to be stuffed somewhere) but the drum is comfortable
if the difference in checkout is not a problem - take this one.

1.5 hours is not so little, you should also add power surges with unexpected loads on the mower. 3x1.5mm is theoretically sufficient, but it certainly does not meet the requirements of complete safety. This 3x2.5mm reel extension cord is the most suitable for your needs, in addition, convenience to roll up and store, and little difference in price. There will only be a problem with the connection, the mower has a socket with a protection (plastic tabs for the plug) and not every plug fits.

A colleague is joking with this piece of wire with 2 plugs?
Such a thing is very dangerous and does not meet any safety requirements.

A colleague of the post below wrote that there may be a problem with the connection, but since you are using it, I understand that this problem was not there and everything was fine?

Maybe he'll get me for it .My neighbor owns a 1300W mower and powers it with a 50m "dedicated" extension cord similar to this:

1-socket mower extension cord with grounding

Some also use universal rubber extenders:
Construction rubber extension cord H07RN-F 3g2.5 40m
but here there may be a problem with the plug (embedment depth) and its connection.

You can also buy them on well-known auction sites.

@ Iwka13 We have mowers of the same power and I use 1.5 mm2 - mowing time at least similar. You can easily buy (as you get) 2 x 1.5 mm2 for the mower - it will be lighter.
The extension cord on the reel is easier to roll up, store. Just remember that before connecting a device with this power consumption, you will probably have to expand it before use (important). Look for orange, white - not green

Ok, but is the extension cord length also similar? Because I have to buy as much as 40 meters.
So I wonder if it would be safer to buy the one on a 3x2.5 drum (as @prpd advises).
Colleagues above also wrote about the loss of power over such a length and about safety itself.

And how is it with the power consumption? Does a 2x2.5 extension cord pull much more than a 3x2.5 extension cord? I am totally green in these matters, which is why I keep asking, because every electrician in a shop is a different story

Because if you buy anything Chinese, he does not have the assumed 1.5 mm2. That is why some of them are so expensive, because they have security and appropriate sections. The ones that I showed you meet these standards. Maybe you can buy it cheaper, I do not question it, but remember that we buy an extension cord for years.

Iwka13 wrote:

Nothing is pulling only 2.5 mm2, you can load it more and give it a longer distance.

@ Iwka13 I also use with this mower: 1.5mm2 50m.
The 3 x something_tam extension cord will be more universal, as he wrote @K-rzysztof Reszka .
However, something for something. Universal but heavier. I use extension cords 3 x something_tam, but I need to connect, for example, a transformer welder. However, my (because I do not know if each) mower, areator, vertukulator, tiller, car charger and even a pressure washer (as I remember) are in protection class II, so I can power them with a 2 x cos_tam extension.

They wrote well. See in this post there is a link to the calculated voltage drops: http://jackiewiczowie.blogspot.com/2014/10/spadek-napiecia-w-zaleznosci-od-dugosci.html I will write this: definitely do not buy a 1 mm2 extension cord - there is probably most often in supermarkets. As for voltage drops, whether it will be a problem, it depends, for example, on the voltage in the sockets on your plot. In turn, to ensure safety, it would be necessary to invite an electrician who will check the extension cord and select the protections for it - then a separate circuit would be useful to power devices connected via the extension cord.

The area to be mowed is the area next to the apartment building, so I guess there are no too great surges in voltage. At least I haven't noticed anything like that at home, and there are some of these devices :)

As for the cable - then there is nothing to skimp on. I'll buy the one on the drum. The difference in price is small, and you don't buy such a toy for a year :)

And not a petrol lawn mower better? 40m is a long distance and the eternal trouble with winding the cord, not to mention the nuisance of mowing. You have to be careful not to cut it, so as not to get tangled. When the grass is wet, it is scary to mow, and maybe the cord is worn somewhere. I don't trust security in 100% either. I do not know. For me, an electric mower has a raison d'?tre in the case of a mowing area of up to 4x4 meters.

The petrol lawn mower is not an option, because first of all I have already bought an electric one, and secondly, oil change and other flowers of this type are not for me. These are not my vibes.
Electric is OK for me. I never mow when the grass is wet, and as for the rope - I'm used to it

And I forgot one thing about that drum and extension cord.

It depends on the mower - some have their own cable, several meters each. and then no problem.
However, some are made so that they have either a 0.5m "stump" or a plug prosthesis to which you need to connect the end of the extension cord - then you would have to buy something about 3-5m to connect to the drum.

But wait, I don't understand something here. So, to connect the mower to the drum, do I have to buy an additional cable? In my case, this is the plug.

We do not know the mower model and the method of its connection.
And the drum near the mower or driving with it as additional ballast is quite a chore.
I think you will have to compromise and consider two options:
1. purchase this "dedicated" mower extension cord (no problematic connection, Polish product - full 3x1.5mm? as stated above.
2.Buy a drum 3x2.5mm? 25mb and a 3x1.5mm? 20m mower to it (a plus is a thermal fuse in the drum, safe operation for the engine at this distance, the possibility of connecting the whole thing without additional interference, not always full 40mb, better winding) if you already have one of them, just buy the other one. .


Garden or mower extension cords have the advantage that they are especially bright in color so that they are visible in the grass.

The mower you purchased is a Stiga Collector 40E

The second very interesting proposition to consider
Thanks for the idea.

I have another concept, but for a "dedicated" extension cable
and I would like your opinions.

Sometimes it happens that I cut for 2 turns. And now one part is practically under the house and a 20m cable would suffice here. I'm talking about a 3x1.5 extension cord
http://pajm.pl/ps-us-3x1-5mm-20metrow-h05vv-f...w-pomaranczowy-acar-ps-us3x1520mp-p-1604.html

The remaining part requires a 40 m extension cable.

And now, is it better to buy one 40 meters long or twice 20 meters each?

How do you view it?

This mower is definitely not a market product and I can see that you are investing for years. I do not know if you took any stock for these 40 meters, and it is worth having one (various obstacles). If you do not mind winding the 40mb cable and you do not plan to connect other receivers in the garden (evening lighting, electric grill, power to the pool, music sources, insecticide lamps, etc. even occasionally) or powering a pressure washer or vacuuming the car in the driveway, then the choice is one section 40 meters.
Two sections have one more advantage, the most vulnerable is the one next to the mower, and in the event of damage, the cheaper and shorter one is replaced, as well as the entanglement of the 40m section.
And if the drum is a 25mb better purchase.
I add a drawing of your mower connector and extension cord that fits there:

OKAY. I bought an extension cord.
Subject to be closed.

Many thanks to all gentlemen for their advice, suggestions and time :)
