[QUOTE="Fleeting, post: 509547, member: 33702"] The simplistic way of looking at it is that the enclosure should not promote/spread fire hence a metallic enclosure or containing a plastic consumer unit in a metal enclosure. You need three things to aid fire, fuel, heat and oxygen remove any one of those and the fire cannot happen, plastic consumer units are the fuel so replacing it with metal removes one of the elements needed for fire. Consider fire extinguishers, water removes heat and foam removes oxygen these are the basic principles for fire exhaustion. [/QUOTE]
