Recessed downlight installed incorrectly

Recessed downlight installed incorrectly

Everyone likes a recessed downlight, but they must be installed correctly.  These cables came from a loft where the builder had covered the downlights in insulation.  The heat from the downlight had no where to go and built up until all the insulation on the cables melted and there was a big bang and flash.  Turned the connection block a nice colour.
