My Wireman mentioned i will be charged higher in the TnB bills if i convert it from single phase to three phase, despite the usage (Kwh) is same.

I wondering whether is it true? as my house title is "Residential" and i check with TnB Traffic Online, it only have one traffic table for residential houses. Therefore i presume the TnB bill will be remain the same after i convert it to 3Phase.

anyone have the before and after experience regarding this?

Thanks.

Noted. Thanks. I am going for 3Phase then. Easier and feel Safer on the overloading.
Banting Area, Still having 3Phase Promotion? will go over and apply by year end.

Upgraded, it just a simple process as drop by kedai TnB to obtain the list of contractor, then pay the services, then come and install the new meter in 2 weeks.

as residential, Imbalance Power Factor Ratio is no applicable to Residential Account Right?

Total RM800 only, including constructor fee RM300 and TnB Application + Deposit Topup.
The rest will be your own internal cabling. This is is depend on your house electrical design already.
