Can check if existing wiring is done on 1phase, if want to change to 3phase, is it possible? And will I need to redo all my existing wiring?
change to 3 phase from 1 phase, can we do it outself?

QUOTE(stormer.lyn @ Oct 22 2021, 09:33 AM) Can, yes, no Thanks. You are electrician? Haha, just wondering whether it is worth to do.  (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. |

QUOTE(ceo684 @ Oct 22 2021, 11:24 PM) Not required to go 3phase if total load never trip the whole house MCB. I see. Thanks, since house currently using smart home setup, and previously electrician did warned about it. It should be sufficient as long as you don't operate all your electric cookers + all aircon + all WH on simultaneously. Last time my place's incomer only 40A so previous owner already upgraded 3phase. But if your incomer is 63A I think its not required to do 3 phase. Guess I will monitor and upgrade when the trip become more common. ceo684 liked this post
