guys, i'm still confused about 1phase to 3phase.

landed house. supply is pulled serial stretching 4 houses. pre-existing 1phase with 60A fuse outside.

right now from reading TNB website, it sounded like i can magically change only meter and nothing else. please enlighten me.

--

(1) do i need to change meter etc outside? yes

(2) do i need to change fusebox inside?

(3) do i need to change lightning breaker?

(4) do i need to change breakers inside?

(5) is there new additional -whatever- at board inside?

(6) do i need to change wiring to wall switches, 3-pin sockets, and fixed appliances (including air conditioners, lightings, fans, heaters)?

--

just additional info; 8hp spread over 6 inverter airconditioners.

if all it takes is just to play with the 60A, possible for to get higher fuse, example 80A (i just tembak a higher figure as illustration of the intent)? or no possible with 1 phase? of course need to replace the related fuses and breakers, inside and out.

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.
