The attached metal fuse box is in the escape route in a small block of flats (with an evacuation procedure). Is it sufficiently fire resistant, or does it need additional protection?
-
In theory yes, that was the point in the change in IEE Regulations requiring installations to use boards in non combustible housings.
-
When you say an evacuation procedure, I assume you mean simultaneous, so fire detection is nearby.
So, we can enclose (hide) it in fire-resistance and in the event of a fire it burns away until it finally breaks out of its enclosure (bigger fire) and activates the alarm. By that time we have lost the only escape route from the building. Or,
We leave it the way it is, people pass it every day and notice anything amiss, if there is an issue, the detection activates earlier giving people more time to evacuate past the unit.
Compliance or risk assessment?

Thanks for your replies.
Dave, according to your logic, we then shouldn't be enclosing any electrics in fire resistant compartmentation (unless there is detection within the cupboard) - which is obviously against all the guidance?

No, just in the specific example. Converted block with a single staircase with detection in the escape route.
You only have one escape route, I want to know about a fire as quickly as possible.
