pickytan,

this will depend on what kind of a/c and what temp-range. i am running 6 a/c (total load 8 HP), 3 fridges, PC, laptops, TV, dishwasher, oven and some other stuff on sgl phase - no problem. but all electric is inverter/AAA energy rating. all used at the same time. temp range for a/c is 29,28,27 degrees only

thanks for the info. i will check this out for my house

i cant answer any of your questions besides 4) though. 5 a/c should not be a problem if you dont use full power setting and inverters. i am running 7 HP inverter A/C 24/7 (but on 28° only) and the normal remaining items (all AAA and above) on single phase wiring and dont have any problems at all.

AAA is the energy rating. we make sure any appliance we buy is at least AAA or higher (lowest consumption). saves a lot in the long run.

numbertwo,

that totally depends on what phases are hit. my area : rarely one phase or two only hit. most of the times all phases are off. but yes, if only one phase hit (and i have no power) my neighbours are with 3phase are lucky still can do whatever cause they have power. but then again TNB is very quick in fixing issues. hardly ever have outages that exceed 30 minutes and outages are really quite rare these days it seems. maybe 1 tops two per year.

sorry yi_min82, but that makes no sense at all.

i have around 8 HP total A/C on single phase on at the same time. no problem at all - but i use inverter A/C.

it's not the quantity but the total peak load. all the other statements are blanket statements and dont give you a real insight. they are "guesstimates".

its probably best you check what appliances you intend to use and how. then you can assess your maximum load and choose accordingly. with today's electrical appliances you use much less power in total and more importantly peak loads are lower (remember the old aircons with a seperate starter point, the start-up load was too high so they couldnt be used with a normal 13 Amp plug, now even a 2 HP inverter doesnt have a problem with a 13 Amp plug). I think the wisdom 4 (or whatever) aircons or more = 3 phase wiring comes from the old old high start up loads.

i can even run all a/cs, my fridges, pcs, etc. and on my oven to bake a cake and 1 phase is still fine.

the heaters might be an issue. what heaters precisely? i have "traded-in" the good old electric heaters with a whole house gas-water-heater from rinnai.

some of the heaters suck over 3000 W and they have huge peak loads.

i 100% agree with weikee - no reason for any "sound mind" to say differently. unless you need it (which in most cases you wont) there is absolutely no need for 3-phases.

2 a/c only and not even on 24/7? why is your consumption so high? you must have serious room for reducing your power consumption.
