Hi expect need your advice on the electrical stuffs.
Previously I did for water heater point x 2. The wireman never add extra at the MCB but instead tap from the existing point. If not mistaken they tap from my 13amp but they change the fuse to 20amp. They mention one point tap from 2 13a soure, eg neural tap from one 13a and life from another 13a. That time I also blur blur believe Ok.
Now I want to add 2 extra air con point at my upstair room. I know many of them tap from standard 13a plug. But since my 13a plus already been tapped for heater.
My idea is, add one MCB for upstair to support 2 x heater point (rewire) and 2 x aircon point.
For my my lower ground extension, i want add one oven point, 1 x 13a with 2 socket loop, 1 x 2.5 for lights and fan.
Agak agak how much. I think need to change my current MCB, only got 2 kosong tempat.
So far so many forums ask advice, has anyone already start their reno work?
My plan is end of the year or early Y2013. Must wait after 2012.... haha.

very dangerous water heater looping....eventhough the contractor change the fius, this make even more dangerous cause the system will not tripped and will burden the wire.....the wire will generated heat..long term can cause fire and shorting..VERY DANGEROUS....
if you wan to be save if do not want to rewiring the heater, you can buy the tool heat scanner/gun that can measure the heat of your wiring (on both the heater and shoot with the scanner)....
for aircond and heater must pull direct from DB....
since you want to put extra DB..better change the heater wiring....
one more thing...DO NOT USE CHINA BRAND WIRE.....use only Sirim Approved such as Mega brand etc...
below is basic formula for wiring for you and other forumer...consider this also as TIPS:
Wiring
Downlight(lighting) around RM60-65
Downlight (lighting) loop RM40
Aircond cable 2.5mm RM150
Socket cable 2.5 mm RM120
Fan Rm70
Water heater 2.5mm RM150
Wall light RM60
Upah pasang light RM5-RM8
Upah pasanag fan RM20
Oven 4mm cable RM200
My house i design my house with 2 DBs...at back DB using 16 mm wire size....my advised to you...for your upper DB must use at least 16 mm cable from meter....
want detail inform me...
good luck
