DB for hotel in Australia
DB for hotel in Australia
(OP)
Hi,
In some countries they use one DB above the false ceiling for each couple of hotel rooms. So each floor will have one DB and several sub DBs along the corridor, above ceiling.
Can someone please tell if this practice is used in Australia? would the location above ceiling next to an access hatch be approved or considered as restricted under AS3000-Section 2.9.2.5?
Just why do they use this kind of sub-distribution in a hotel environment? Why not just straight circuits from the floor DB?

RE: DB for hotel in Australia
I can't answer the question since I'm on the other side of the world -- but I have a question for you, just for my personal edification: What is a DB? I suspect you mean distribution board, but I've never used or read that term myself.
Thanks and good on ya,

The reason for doing smaller boards is because it is much easier to add a new circuit, rather than run all the way back to the floor db. That and it would save on cable runs. I personally would be a bit concerned about putting them in the ceiling.

but i think it is good idea to make it on thecelling

PS. Yes DB is Distribution Board and that is/will be the new term for it in IEC 61439.3. Refer this link:

That is the name also given to them in AS 3439.3 and IEC60439.3. Refer the last two words in the extra long title:

After the introduction if Section J8.3 in BCA and the requirement for separate metering for lighting, power and HVAC, the use of one DB per room or one DB per couple of rooms is very complicated.
Thanks niallnz for the tip regarding the RCBO. I think the first GPO in the room can have the RCD on board, as in hospitals (AS3003).
Cheers.
