[QUOTE="boltonsparky, post: 506033, member: 4678"] Interesting input from everyone, cheers. I've seen a few remnants of consumer units after fires online and one in the flesh and the breakers seem to fair quite well and not act as a fuel, they melt a bit rather than burn whereas the plastic housings are non existent so must burn well. Being metal removes a large amount of the fuel. Taking that into account other than the cable insulation I suppose there isn't a large amount to burn so spread from the consumer unit is less likely and why fire sealing the backs isn't worried about too much. Obviously prevention is better than cure so proper terminations are key, surprising how many tails I come across that are loose in the main switch. All the metal ones I've come across have had the metal lid over the MCBs that annoyingly won't stay open, is this part of a British standard to help fire proof the front, unless being held open the lid will be closed covering the front?
