Regards,

Seems like a lot more panels than necessary.

And you only have one line shown to each panel? That seems odd, but I'm not sure what your voltages are there.

Are all the panels only supplied with a single line-neutral supply? Is one pole of each of the two pole breakers for the neutral wire?

My guess is it is similar to what you see in European systems, maybe a 415/240 wye system. To each sublocation is just one phase and neutral. Having 6, 10, and 16 amp breakers in there suggests it is not an NEC application either, but the 40 amp kind of seems odd for IEC applications also.

G'day kwired,
Sorry for not getting back to you sooner- thanks for your comments appreciated--had few days off---feets up---lion hunting trip !! 30deg sunny --:D
Let me clarify:,
Yep. Voltage system is 415/240Vac Euro system. I agreed with you & Steve66, it is a bit of overkill to do this way, i.e one panel for each room..while we could do that 2 - 3 rooms shared one panel... but this is what the owner wants and i guess he's more concerned the electrical maintenance down the road and shortage of skilled techs in his area compared $$ few dollars.
The reason we are doing this way is to save energy - people tend to leave hotel rooms Aircon and lights on! to reduce this energy wasteful thing each room will have "energy saver" box that gets connected to each subpanel...Just as the guest inserts their key card into the door lock will gain access to the room...In hotels outside the U.S., it is common to find energy-saving technology for turning off the lights and power in a guest room. Insert your hotel room key card in .....finally, Steve66, the plan is to have one phase and neutral to each sublocation as kwired guessed... The breakers are for room lights, sockets w.heater and A/c...size will depend upon the appalinace ----Subpanel main breaker could be 32Amp as per IEC...hope this getts me off the hook:happyno:

regards,
Mustafe
 
Why are you using 3Ph MCB’s for 1Ph loads? In the event of a fault in a single room three rooms will loose supply.

If this is to be done to BS7671 you need to revise the OCPD or the cable feeding each room. 63A is way too high for 4mm².
 
Somaliland falls under the IEC umbrella not NEC. 30mA RCD’s or RCBO’s will be required for all socket outlets.

A 32A SP+N RCBO for each room feed will satisfy the 4mm² over current and earth fault protection requirements.
 
If using said energy management equipment and turning off an entire room when not occupied, sounds like an individual distribution panel for each room is likely one of the easiest ways to do that.

Outside of that most any other details you seek approval on are outside NEC scope and this is primarily a NEC based audience here, most of us have no clue if your design is up to the codes/standards where this will be installed.
 
I’m sorry I should have stepped in earlier, the IEC and NEC are at times at odds with each other.

The basic requirements are the same but the methods differ.

C'est la vie.

However safety issues may be pointed out on the basis of code (which I did in my last post) and leave them to OP for his consultation with concerned authorities. I think that is intention of OP also.

Tony, point taken, i should consider that and use SP breaker at each end, the feeder for each room will be revised accordingly.The only minor debacles i could see with that arrangemnts is the need for a bigger panel...i.e, there are more than 30 rooms on each floor....
with regards to the IEC and NEC i guess they vary according to place and social setting...i could be wrong.

You have to use which ever code applies where the install is taking place. Does no good to use NEC on European style supply system because you will run into some issues that NEC doesn't account for with those systems. With NEC in a hotel room 210.60 will require certain 15 or 20 amp 120 volt receptacles, yet your supply system doesn't even have any conductors with 120 volts between them. There is also conflicts between the two codes concerning GFCI, AFCI and RCD requirements. You need one code or the other, not a combination of both.
