Emergency Power System
Former Community Member
Say you had a building that needed backup power. Do any British Regs require that the loads be subdivided onto different branches and different automatic transfer switches based on type and priority?
I think that you may be looking at the problem back to front. I know that some industries/types of building (good examples being a hospital or a nuclear reactor safety system) will have requirements for the back up/emergency supplies, but this will be set as requirements/guidelines for the power supply to be provided to certain services rather than stating the subdivision of a provided emergency supply. The requirements will talk about the independence of the supplies, the required duration and the services to be fed. There may also be differences in the automatic change-over switches as some services may allow manual change over (e.g. a nuclear reactor won't go from safe to meltdown instantaneously so manual change over may be acceptable but a patient on the operating table in a hospital might die in the same time duration so automatic change-over would be more appropriate).
You will need to look at the industry you are interested in to see what requirements are there.
