Fuse is tight! Struggled to get it out to see the ampage! Hard to tell with the brown wire as it's melted, the fire had been blowing for a good four hours though before i smelt the dreaded burning plastic! Lol
 
Cheers everyone, I'll let you know what I find tomorrow out of interest.

I'll try plugging something else into the socket and see if it gets hot, or I'll buy a socket tester
 
Think I've made a schoolboy error

Running a brand new 2kw electric fire from the mains via an extension.

Smelt burning tonight and found the plug and socket housing red hot after the fire switched itskit off.

Checked the extension plug to find it has only a 5 amp fuse inside.......

Is this the most likely reason the plug and socket got hot or is there something more sinister with the fairly new socket?

Cheers
Was the extention lead coiled up?? Any loose conections any where??
 
looking at that, i'm going to design a coal fire that looks like it's electric. will be all the rage among the "keep up with the neighbours" brigade. this time next year i'll be a millionaire.

and it will revive the ailing construction industry as builders will be busy fitting chimneys to the silly new builds where the developer has forgotten to include them.
 
[ElectriciansForums.net] Schoolboy Error 2kw electric fire If you look at the attached curves, you will see that a 5A fuse will run at 8A for a considerable time before blowing, but the fuse will be getting very hot which is probably what caused the insulation to melt in the plug top.
People think that if you stick a fuse in it will blow as soon as it hits the rating of the fuse, this is simply not the case.
I went to a school a few years back, the DNO’s fuses were rated at 300A, but for most of the school day in excess of 400A was being drawn, fuses were failing about every 6 months due to fatigue and the cut-out was so hot you could not put your hand on it!
