it's <3yrs old.

i haven't sum the total possible amperage, but right now can confirm at least 5 a/cond running at same time, sometimes all 6. and people and tnb said general guide to consider 3 phase is more than 3 a/cond.

morning and evening - 2 heaters also running.
with internet, home automation, lighting, fans, cctv, freezer, coway dispenser, etc etc.
haven't moved washing machine and dryer yet.

so i am just exploring if 3phase is necessary before the house gets unwieldy to do anything anymore.
my wife bought house without consulting me; was coerced by developer to submit TNB form when collecting keys. I would have asked about 3phase upfront if i knew it.
it's late and expensive now, but i still have to enquire since i expect more appliances.

Hi all,

My new 'semi-d' house came with single phase electricity unfortunately and am currently exploring options to have it upgraded to 3-phase. From what I heard from my electrician, it seems that the supply from TNB to my house meter (at the front gate) is already 3-phase but this dumbo developer, for somewhat reason, pulled single phase from the meter to DB / house.

If I need to upgrade to 3-phase, need to hack the internal wires / cables in my house? Means from the meter all the way to the DB box? (in store room).
