Where do you get the idea that 3 phase would lead to lower electric bill?
It all depends on your consumptions. You still own the same electric and electronic devices that consumes the same amount of electricity while on 1 phase or 3 phase.

Btw, back to the topic. Look at your "fuse box".
If it's only 1 row of fuses than that's single phase. If it's 3 than it's 3 phase.

Nowadays, most house comes with 3 phases especially landed properties. However, for condos or apartments; a single phase is enough as you do not have many plug points. Ppl uses 3 phase because they have lots of plug points and do not want to overload one single phase of fuse.

DB box is quite expensive.
My friend is changing the DB box for his single fare and it cost around RM600 IIRC.

My house is with 4 airconds and sometimes all 4 are on at the same time.
Single story house with 3 rooms and 1 living to give an idea why 4 airconds.
Lots of laptops hanging around, at least 4 and 1 PCs. So far with everything on at once including the washing machine; the single phase set up didn't give any problems.

err, maybe you can try post in Mandarin and we try to translate.
Because I don't really understand what you meant. I bet others are also blured with your statement.

What I understand from your post is you're saying most electric appliance doesn't come with 3 pin plug thus it is not meant for 3 phase? Is that what you are saying?

Thanks for the explanation. Much more clearer now.
So can we conclude that it doesn't save as far as the myth of 3-phase wiring is concerned i.e. only reaches the DB box.
