so there other night i used my new 3 kw iol rad in the back of van overnight,
went to look the next morning and it wouldnt turn on! thought the rad had broken so unplugged it from the extention reel (also brand new) plugged it straight into the wall power point and it worked!
so what the heck is wrong with plugging it into an extetion lead?
help please

-
they turn off when they reach a certain temp
-
did the extention have a built in RCD switch ?

na, it wouldnt turn on even when i turned the themostate while plugged into the extention reel!
-

Darran
is that the same as a reset button? if yes then it does have one of those yes!
-
i know its a stupid question but is the lead working have you tried something else in that lead?
-
Your overloading the extension lead

oh really! so i need a better extention reel?
-
Does it say the maximum load on the extension lead.
3kw is quite hefty
-
Have you checked the fuse in the ext lead? Can't be anything else, unless faulty wiring.
-
I reckon you are over leading the extension reel.
A lot of the domestic cheaper one's are rated for about 2 kw.
Might be worth checking.
-
Goerge am I missing something here? the title of your thread is Oil fill rad failed!
If it's an oil fueled heater why the heck do you need electric ???
-
Oil filled still needs electric to work.
Not unless he held a seance to try and get it working that way ;D
-
my new extention lead says the following...
Max current
fully wound 4 amp (960 w)
fully unwound 13amp (3120 W)
hope this can shed some light on it
thanks
-
Was your extension lead fully unwound when you used it?

no, was this the problem? how the hexk does that make a difference? ???

As far as I know you have to unwind the extension cable fully. Might be worth trying to see how it performs.

seems strange but yeah i'll try it tonight! thanks mate

can anyone explain the reasin for this?
-
Cables can overheat if coiled up on a reel. I don't know if this is what happened with yours?
But it sounds as if the problem may be related to your extension lead somewhere along the line.

oh right ok, thanks for the answer mate

If you don't unwind all of it, you are making a giant electro-magnet. And it gets very hot, very quickly.

oh right, thanks alot for that mate! right im off to unwind it all! now!
thanks again everyone!

OK ;D I thought you Guy's were referring to paraffin type heaters :o I'll get my coat ;D

you need to fully unwind any extension lead, or they become a serious fire risk. Your lucky the van was still there in the morning.

but at least what might be left would be nice and warm........... :-X

bloody hell im luck y then ! :o

no really GB that is why your reel has an rcd to cut off before that happens ;)

oh right, i see! by the way what does rcd stand for please? thankyou!

residual current device, if it gets overloaded it cuts power, but cheaper reels will not have it so you must have a half decent one

thankyou. yesh its not the cheapest one from wikes ;D but not the most expensive either!
ive just been to check on it and realized its cut out again due to the fact its pluged into a thin 110 v light cable! so ive plugged it into the other powerpintint which has a thicker 320 v cable! at least thats my new theory! 8)

can anyone explain the reasin for this?
A coil of wire such as your cable on a drum can create a magnetic field with a high current draw. It works the same way as a field coil in an electric motor. The magnetic field can cause the wires to get very hot and melt. We used to see this quite often in the power tool industry where motors with high current draw were on unwound cable drums.
Happened more so at high altitude (6000' above sea level) and in the hotter months.

Always unwind leads, especially if running 3kw and double especially if using on something like a rad where it'll be running for hours unattended.
