I have posted a piece here which is also on the TT topic, but is more general and I think a new thread would be better. Your voice is heard. See below.
How much longer does a metal consumer unit contain a fire for? I imagine the building still burns down, admittedly it might give the occupants a bit longer to escape. But if your asleep and your board catches fire its not going to make much difference surely? The real issue, like you say Dave, is the cause of the fire that should be addressed, not the containing the problem for a bit longer before it breaks out and burns the house down
