Loose connection in the LH henley?

 

[RF Lighting]

That looks like a rather puny incomming cable.

I guess it over heated and shorted out?

 

[333rocky333]

no afraid not, nothing loose or shorted, in fact supply on and everyting working just fine

 

[RF Lighting]

Has it just boiled all the pitch out of the bottom of that old cast iron cutout?

 

[333rocky333]

It has got vey hot and the pitch is all bubbled up now so they are gonna upgrade it asap

But something else caused it and it wasnt the head and no it wasnt a fire in the cuboard that caused it

 

[ricicle]

Water leak ?

 

[RF Lighting]

The seals are missing from L2 and L3. Has someone shoved bigger fuses in one or both of the fuse holders?

 

[plugwash]

My first guess was that some numpty connected two phases to the linked out main switch.

 

[Lectrician]

A dropped wire coat hanger?

By the shape of the plume up the board and the cabinet above it, it looks like you've had an 'eruption' from the bottom, and by the soot on the 2 left hand fuses it's come from under them. As RF has already guess a cable overheat, I guess it's the modern earth clamp at the bottom of it has caused a problem and simply by chance after the eruption, the supply has stayed in and the 'fault' has burned itself dry.

edited to add......Mind you if the clamp has produced a fault from being too tight, after some current flowed, I can't see it being still on the wall

Actually caused by someone using an angle grinder about 2 foot from the board

What was being grinded, ( or ground ) ?

The PILC cable, by the look of that soot!
