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. DaveD [Non-text portions of this message have been removed]
