Manufacturers will be producing non combustible plastic boards very soon. Non combustible insulated boards like the old respected solid Wylex 604 IVY. Now, they would not catch fire easily, and if they did get very hot they smelled like fish as a warning. I loved 'em. Z.

Most of the evidence surrounding consumer unit fires suggest that in the event of a overload or fault the fire originates outside the oxygen starved unit where the cables are, soft plastic, dirt, dust and other flammable materials such as wood then migrates to the consumer unit, whilst it is true that metal will not suffer in this sense at least you can wire brush and paint the unit with hammerite saving your customer some costs. Definition of non-combustible: BS 476: Part 4: 1970 Non-combustibility test for materials. This test classifies materials as either 'non-combustible' or 'combustible'. It is the most stringent standard for the fire performance of materials and gives a measure of the heat and flames generated by the material under standard heating conditions. Non-combustible materials can be used without restriction anywhere in a building. Their use ensures that hazards due to smoke and toxic gases are "minimised" and that the fabric of a building will not make a contribution to a fire. regards ------------------------- "Take nothing but a picture, leave nothing but footprints!" ------------------------- "Oh!
