QUOTE(sovietmah @ Oct 19 2021, 06:53 PM) any one knows there is any diff on electric tariff bill between single phase and three phase? Tarif would be the same for 1phase or 3phase. U need 3phase when ur load exceed 10kW or 50A https://www.tnb.com.my/residential/my-tnb-account/ sovietmah liked this post

QUOTE(yuen300 @ Oct 22 2021, 01:58 PM) Thanks. You are electrician? Haha, just wondering whether it is worth to do. When u replace ur single phase meter to 3 phase meter u should balance ur load accordingly & this might involved rewiring internal load.(read the cost could go to replace could go to 10k) Currently, have 5 airconds. But usually only 2 airconds will on simultaneously. Perhaps during CNY, will on like 4 units together, for a week. Or u can let it be but if like that what is the purpose of changing to 3phase? Or possible ur gonna planning for future sub-DB which only u know ur future usage mushigen liked this post

QUOTE(chongkiatz @ Jun 30 2024, 10:03 AM) actually 3 Phase will save alot electric bill compare to 1 phase? Its not really to save energy but more for a better electrical load management my house normally only turn on 2 aircond at the night , 1 normal fridge , 1 normal topload washing machine and LED downlight if changing to 3 phase will make huge electric saving price? According to tnb, https://www.mytnb.com.my/business/get-elect...ade-electricity WHEN TO CHANGE You are advised to change from a single-phase supply to a 3-phase supply when your household electricity load exceeds 10kW or 50A. As a rule of thumb, if you have three (3) or more air conditioners in your home, you should upgrade to a 3-phase supply as it will increase stability and reliability of electricity supply. |
