Discuss Hospital Emergency Power System in the UK Electrical Forum area at ElectriciansForums.net
No break, or just Stand by?Nope, genuinely would like to know. Say I'm designing a hospital from scratch to modern code.
No Break, exactly what it says no break in the supplyOk, I'm learning all ready. What is the difference? The building never looses power vs just enough for what code requires be backed up?

Stand By, Loss of power, everything dead until Genny takes over.
The reason I ask, is this is a forum of mostly UK electricians. So will not be able vise on US code.
Normal supply run through an on line UPS, power cut, UPS takes over until Genny is up and running and takes over from normal supply, load shedding is in operation to shut off all non essential loads.Like an uninterruptible power supply with a battery? What loads get that or are required to?

Ok I'll bite, why do you want to know everything about hospital power supplies in the UK? I would genuinely like to know! After all;
I would say it's up to the Hospital Authorities to deem what constitutes essential and non essential loads, and of course the way the distribution side of things have been designed in the event of a power cut.What loads would the UPS supply?
Also are the receptacles serving patient care beds fed by a dedicated electrical branch or ATS?

Which suggests you know more than your profile is showing. I only ask as it is helpful to know your knowledge level to pitch the answer accordingly. As you have asked about a highly technical subject matter.I can tell you everything you would ever want to know about other places however.
No idea, was just responding to your question regarding what is "No Break" and "Stand By" by my understanding and experience.Do any specific regs govern the design of the system or what loads are deemed needing backup?
AgreeBS7671 is the general regulations that cover UK installs, but there will be more specific British standards to follow.
Your profile says you have changed flashlight batteries and lamps indicating you are not an electrician. At the same time

All these long words are doing my head in ,please speak down to earth EnglishI've learned about them, but now want to learn about the UK.
Pitch without a filter, speak your mind. Its the easiest for all of us.
And if you ask me its not all that highly technical. Get into epigenetics or quantum mechanics and that it really becomes esoteric.

Any helpAs I said, I'm not afraid of what ever you throw at me
There is some mention of hospitals in BS7671 in timing of generators switchover and earthing systems peculiar to hospitals.
but what do they mean by "risk grade"?
It's not law that would cover it, it would be Health Service Policy.And one question- I can legally supply backup power for the whole site via one ATS?
The level of Risk of an electrical supply failure causing harm to Patients and or the Business.
Example,
Loss of power to Car park lighing .
Risk Grade 4. Consequences, low risk of trips and slips.
Loss of power to Operating theatre.
Risk Grade 1. Consequences, high risk of loss of Patient life.
So what would mandate multiple ATSs?
Anyone have a single line of an actual UK hospital?
I doubt actual line diagrams of an in service hospital would be available online. However there may be theoretical ones.
It's a bit of a niche subject.
Can you define what you mean by ATS. I presume alternate supply?
Nothing government funded? What, the NHS is gov right? Then they should have single lines out there.
ATS= Automatic Transfer Switch
They will have single lines out there, but for obvious reasons, detailing supplies for hospitals are not likely to be available to the public.
In the same way military bases, water treatment plants aren't.

I'm still thinking this may be a wind up.
Why the particular interest in the electrical systems of various countrys' hospitals? Seems a bit specific.
