I'm sure  I remember reading somewhere that electrical cables don't like  
polystyrene, they need to be sheathed perhaps


The plasticiser in the cable sheath reacts with the polystyrene insulation,  
causing the polystyrene to dissolve. When the polystyrene has reacted  
sufficiently, it reaches a point where it stabilises - that and the fact that  
the 
polystyrene eventually dissolves sufficiently for it to move away from the  
cable so the plasticiser can no longer reach it and so the reaction will  stop.
 
However, it is best to do something to prevent cables from reacting, such  as 
putting some sort of barrier between it and the polystyrene.
