anyone know how much is the wiring cost if i want to move the electric meter from inside house to outside? old house the meter is inside and tnb can't take reading if nobody at home.

Outside as in at gate or autogate pillar?

When testing my house wiring, i switch on all my 6 units of a/c + 2 water heater, My ELCB did not trip, only my main fused beside the meter blow after about 10mins of used. That is because the fused was rated 40+ amps (think it come from 3 phases) free from my electrician. Change it back to 60Amps, that should allow me to handle up to 14,440 watt. More than my 6 a/c + 2 heater. 

ELCB is Earth Leakage Circuit Breaker

Yes, and earlier is my typo error, is the main CB (c63) in the DB box that did not trip.

I always play with this motor or heater and conduct actual test of the ampere running. With the instrument checking, I can see how much the current rushing and how fast it will drop. Even I can put in the same amp fuse without blow it in short time.

Don't worry about the rushing current or bla bla bla. Even if the single phase running max amp, I can simply replace the fuse with a bigger 1. 

Anything with 415v will required 3 Phase. There is no 400V load, country like UK tolerarance voltage is betweet 390v to 440v, and usually the equipment that need 3 phase will have such tolerance level. I believe Bolehland also similar.

415V was yesterday. now 3 phase voltage is 400V phase to phase.

A single phase for a house can take up to max 63Amps. Theoratically If all the house in the same row run the load at max, the incoming cable will not be able to take it. Even for 3 phases.

Too bad, its a bad design. My boss will fark me if i do dis kinda work in the panel. Sum of the downstream should not more than the incoming

Please read back what you wrote.

3 phase is not needed, if:

a) ur load can be handled by single phase
b) u dont need 400V supply

For load, i don't deal with 3 phase, maybe is a new trendto use 400v, it does not matter because the equipment should be design to have some tolererance level.

The main TNB wire anytime can handle over 300A. The wire that come into your elcb can handle 100A. And it is very short lenght. The load it not for a single device and it is for distribute. (the whole house)

The changing of the fuse is not like change it to double the amount. And this is for the knowledge people to do it. Not advise for ordinary people.

indeed very true

Are you sure now the voltage drop to 400V? My working place still showing 415-420V. And the single phase still give crazy 250v.

call in and ask the person incharge

Tha changing seem like no meaning at all. 400 + 10% and 415 + 5% ?

And mostly now the electrical applicance manufacturing don't put the voltage at 230v anymore. All state at 240v. Have you realize it? I have long forgotten when they change it from 230v. It seems like opposite way?

Mostly I deal with Japan voltage which is 100v for single phase and 200v for 3phase/2phase. So I didn't realize what the TNB is changing. ( and seems no change at all)
