Hi! would like to seek for expert opinion,

If we change residential title 1 phase to 3 phase,  how much does it cost usually?

contractor got quote need at least 5k. really that expensive?

I ask TNB they just say caj sambungan RM250 and then deposit for residential is RM700 ( if u have deposit RM500 for one phase, then you just neef to top up RM200)

Please advise accordingly thank you!

Regards.

boss convert 3 phase because i have 7 air cond, possible on 5 at the same time, one of it is 2 horsepower.
if 1 phase can support ah boss

How do you know 1 phase cannot support it? have you calculate the power load?

It’s all depends on the equipment wattage. And if you overload, your fuse will blow. you will know you got too much load, and it's time to either 3phase to split load, or up the ampere.
