Smoke without fire?

Not on fire just yet

Overheated doorbell transformer with soot marks up the wall This doorbell transformer has obviously overheated, causing a black mark on the wall and ceiling above.

It was still connected to the mains supply when this photograph was taken - the switches only being turned OFF shortly before.

The MEM fuseboxes are for night storage heaters and the normal light and power circuits. This installation dates from the 1970s when the building was constructed.
