The DNO (UK Power Networks) has specified that the duct that will carry the DNO supply to a new SFH has to terminate into a 1-hour fire-rated cupboard.
The duct will terminate in the basement, and the supply will be 3P 100A each.
Which pre-made cupboards would meet the required specs, or if we want to build our own cupboard how would we achieve the required fire-rating? An industrial steel enclosure is not permitted by the DNO.
The cupboard may be mounted either directly onto a concrete wall, or onto a concrete wall that has some internal thermal insulation.
Thanks
