Saw this on a camping website......

[Euphony]

Apparently it’s a visual reminder as to why you should completely unwind your hook-up cable, I can’t see either end so can’t confirm or otherwise....

Was that on a p1key site where they were stripping the copper out they’d nicked ??

Don't do it wind up your EHU frome facebook

this is from Facebook but a timely reminder Just a reminder if you use an extension lead no matter how short a distance you need it, always uncoil all of the lead, otherwise it can overheat and catch fire, An extension reel is an extension lead that rolls up, usually into the socket end...

A wound cable is basically an electric fire. Think of the old 3 bar fires of old, that cable must of been carrying a fair old load (amperage) or was covered with something stopping the heat dissipating. In an another life on another planet I powered up the Glastonbury festival market areas and saw this sort of thing every year. If you are only charging the batteries, running the fridge and watching the telly then not really a problem BUT good safe practice saves lives and money. PS. If you don't know what to do with the spare cable, loop it into a figure of eight and tuck it under the van. Sorry for lecturing but I have seen some appalling consequences of this kind of foolishness.

nah its Wildbill attempt at making an electric char grill, he posted it last night, but I cant find it on Amazon yet.

I have never never ever ever fully unwound my EHU cable any of the rare times I plug in my van to the mains.

The small amount of amperage my van draws will NEVER EVER EVER create an induced current that will heat up the cable enough to cause a fire...

There are those who worry themselves to a frazzle over all this nonsense... I feel sorry for the Worriers.

Don't you dare come near mine to help wind it up. been told off by electricians and sailors alike, I coil mine in neat loops, nothing annoys me more now than the twisted figure of 8 created by winding round shoulder and elbow

I'm sure we've had this discussion a few times over the last couple of years: the induced current (and magnetic effect) is ZERO because the current which is flowing clockwise/anticlockwise in the "live" lead is exactly cancelled out by the current flowing anticlockwise/clockwise in the "neutral" lead, at every moment in time.

It is a little bit like an electric fire because the current flows through a resistance (or pair of resistors if you want to consider live & neutral), which although small CAN be significant. Obviously, any heat generated has difficulty dispersing so the coil of wire may get very hot.

I feel sorry for those who can't be bothered to look after themselves and, more critically, their innocent neighbours.

I think that anyone who still does not know the dangers of not uncoiling the cable should simply be thrown off any site that they are seen on

 

[Pete5996]

I have a (admittedly rather ancient) Homebase 30m 13A cable reel. On the side is the following warning:
Do not exceed maximum allowable load
720W/240V fully wound
3120W/240V fully unwound
Unwind fully before use

Presumably the warning is there for a reason?

A few years ago my father used a reeled up extension cable and plugged the automatic washing machine into it, the cable melted similar to the first post.

How many of us have an automatic washing machines on board?

Did your father cause any harm to his innocent neighbours?

Thank you for feeling sorry. But don’t feel too sorry because I feel worried about those who are sorry.

Unfortunately not everyone is as laid back,or maybe as knowledgeable,as you.

A lot of us don’t understand this leccie stuff. I do know that I found a half melted coil when we used it at the village Fete a couple of years ago........but it was running to a tea urn,sound system,fridge,and maybe more....!!!!!!

And....better to be safe than sorry,my Ol mum used to say....but she didn’t have a motorhome.

Coils can get hot - I've felt one that did. It was tightly and neatly coiled and had been supplying 3kW of power. Even so, it didn't catch fire.
If you consider that cables are being abused much of the time, yet the number of incidents reported seems very low, we may be over-emphasising the risk involved. Even so, better to avoid such a problem than tempt fate.

I always use the shoulder elbow method, but I unplug first.
Keeps me warm in the cold weather.

Wow Mr dickydo... your insults have no effect on me...

When you have been with us a little longer you might learn this.

Why not answer my questions?

I bet you have never seen a fire started from a coiled EHU cable connected to a mororhome.


JJ

 

[ABZSteve]

I asked our Electronics engineers if it was OK to leave the EH cable coiled. I big fat no was the answer. I trust their expertise and always fully unwind.

You are correct, I have never seen a coiled cable catch fire connected to a motorhome Likewise I have never seen a Blue Whale in real life but I read and learn from people who have

Other peoples experiences and knowledge is the easiest way to learn all manner of things

You should try it sometime unless of course you know everything...

 

[Realist]

I’m an electrician by trade, trust me unwind all your extension leads.

Current flowing in a cable generates heat. This causes the temperature of the conductors to rise until the heat lost balances the heat generated. If the temperature gets too high the insulation on the cable softens and eventually melts.

When you pack lots of cables that are all carrying current (whether multiple seperate cables or multiple loops of the same cable) together heat dissipation suffers resulting in a higher temperature at a given current.

Reels are particulally bad because they tightly pack together a large number of passes of the cable. Excess cable in a loose jumble on the ground is far less likely to overheat than excess cable wound tightly on a reel.

You get away with it most of the time because most of the loads people plug into extension leads are small and/or intermittent. From time to time though the right combination of circumstances come together and melts one.

You are correct, I have never seen a coiled cable catch fire connected to a motorhome

I thought not... but maybe this might be because you have not done much motorhoming yet.

I have had a motorhome of one sort or another for over forty years. I have lived full time in a motorhome for over thirty years. I have motorhome friends who been full timing longer than that.

My knowledge of van life is mostly acquired from experience, both mine and that of many of my friends.

The current drawn by the equipment used in a normal van is not high enough to set fire to a normal EHU cable even if it is not stretched out.

When the outside broadcast trucks come to the Studio where I used to work (and where I still spend time during broadcasts) and plug into all the equipment inside the TV theatre, they don't stretch out all the hundreds of metres of cables they use. Any excess is left coiled up neatly.

I live my life based on experience and not on a load of opinions and info gained from the posts on the internet.

But PLEASE... if folk feel happier laying out all the cable, do so.

Just leave those of us choose not to alone.
