QUOTE(likwho @ Mar 3 2015, 09:44 PM) Today I just contacted the wiring man, I kena ejek by him. Cuz he was persuading me to use 3 phase due to I have 4 Aircond. He told me I have 2.5hp, 1.5hp, 2 x 1hp confirm must use 3 phase or else it will trip. So I calculate the power consumption to him and said its not even 60A how come will trip, he said it doesn't count that way, then kena ejek. So I wanna get confirmation with u guys, is he right or we(all forumers) are right? It won't trip. if you check the outside tnb fuse sometimes it rated 100 A. more than the demand that u have right now. total hp u have 6hp. it is not even close to 30Amp |

QUOTE(supersound @ Jan 8 2015, 01:26 PM) AC's efficiency are only ~50%, need to consider this also  I checked using power meter an average 1hp non inverter AC has a PF 0.99 or 99% efficiency |

QUOTE(silverong @ Feb 22 2017, 04:14 PM) Hello, my house have 6 AC (1 x 1.5hp, 3 x 1hp, 2 x 2hp) and 4 water heater with pump. Normally it is max to 4 AC open in sleep time. Am I need to change from single phase to 3 phases? even if you swith on all those 6 ACs and all 4 water heater at the same time, total amp still below 70 Amp. single phase can carry up to max 100A. |
