1,2,3 is the standard job.
4,5 should be done during main renovation work, as it may need hacking job.
If you do the wiring now, the installer may just tap wire from 1 of your socket points which is quite dangerous on long run.
For me, I don't really like concealed piping as when problem happens, you have more headache.

thanks for your reply... the room is ready as it were... im not going to concealed the wiring...

is that item 4 & 5 is additional cost?

Laying new cable sure need to pay extra.
With such hot climate, when doing renovation, make sure every room have an air cond point.

normally they will do the entire thing cabling, insulation, piping (10 ft), bracket, setup & testing. the only (!) thing they dont do is the power cable from your DB box. either provide a blank wire (conceiled or otherwise) or a free power point to connect to.

little advise: keep the copper piping as short as possible for optimum performance and if you can talk to the installer, ask them to do two layers of the insulation. the foam is cheap. i always do back to back installation and ask them to insulate each pipe individually with double wrap.

Does the new cable laid from DB or from nearest electric point?

most of the time nearest power point..

actually its quite easy if air cond cable is similar to normal our lighting/ ceiling fan cable running...

cause my room fan i install myself including the cabling lolz

If the intention of putting extra points for small load equipment, is ok to tap on the nearest point (in their term is called looping). But if you intend to use it for A/C or water heater, need to run direct from the DB box.

not really, as long as u identify is the load for the point MCB for over or not...
if not u are safe to use...

You never know, especially after sometime, people forgot about it and plug in an hair dryer to dry the hair, while switching on the A/C. And MCB do fail time to time. Very common I see a bedroom with one MCB use and is tap for A/C and use with hair dryer. And some Powerful hair dryer can go up to 2000Watt

agree with u =)

i do the calculation already for the MCB will be using for my air cond... the 16A MCB only cater for my Ceiling fan and 1 Power Outlet, which i intend to change the power outlet to air cond outlet which means the MCB only cater for my air cond and a ceiling fan =)

shouldnt be any problem

meaning to say if power point MCB cannot support the load, need to add new MCB for air cond?

New MCB and independent wires to the a/c unit.

some reading to understand =)

Usually this electrical works to be left for wire man job.

well if you understand this, u may do it... but take note u die dont blame me... lolz my home socket and fan installed by myself lolz...

very easy actually.

Last time when my house after get key and only marking where I need for aircond points, lighting points, water heater points, exhaust fan points and add few more power points all tap from MSB Leh.
Even wiring for aircond they also explain why I used use it bigger size of wire.

If i die cannot blame oredi.. oredi 8 feet under ground.

Ya... normally i will go for 2.5mm cable or go wiring shop ask them what is the recommended wiring... sometimes pay more it is ok... since is ur own home...


lolz... i mean dont ask ur family sue me >.<

Shall be from DB for safety reason, unless you know the plug point wire they used is high quality type.

Sound like here really owner to self DIY...

Inb4 all job is belong to aircond man, wireman, electrical man and alarm man jobs
