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 --
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
