i can only see the 32A fuse.. which is more than enough for a house..
32A x 240V = 7680W maximum load your DB can handle.. ur total connected load is..? lighting, socket outlet, fridge, tv, a/c, w/htr and so on...? |

never assume when it come to electricity...
2hp is only around 1.5kw and not 10kw.. and theres a "faktor pelbagai" (diversity factor) for electrical calculation... example: 1 unit of 20A MCB and be use for up to 3 unit of 13A S/S/O.. This post has been edited by mikicun: Jul 12 2013, 09:53 PM |

QUOTE(sapphirejohn @ Jul 12 2013, 09:53 PM)  what is MCB and S/S/O?   S/S/O is switch socket outlet, usually the 13A 3pin socket at your wall (wall socket)  This post has been edited by mikicun: Jul 12 2013, 09:58 PM |

QUOTE(weikee @ Jul 12 2013, 10:21 PM) Single 32 Amps will not go up to 12kw, but with two 32amp he can go up to 12kw without issue if load are properly distributed. thats because the neutral is for single phase only.. 3 phase doesnt need the neurtral to operate...Std practice is having same wire thickness for Neutral and Live. Than again, if you notice incoming from TNB have 3 Live wires (RYB), and one Neutral wires. Every wonder why Neutral don't need the total thickness of 3 Live wires? |

QUOTE(weikee @ Jul 12 2013, 10:33 PM) For say a row of houses using single phase and is distributed between the R, Y, and B, all using single phase still tap into the same Neutral. correct... the neutral cable already been calculated for... so your point is...what about the earthing? the earthing is always the smallest cable among all..? |

QUOTE(sapphirejohn @ Jul 12 2013, 10:42 PM) I don't think I have to 32A DB because the upper flr does not have the 32A circuit breaker. the 32A fuse is for both DBs.. ground and upper floor..and I notice there are 2 diff color for the MCB? 2 diff color of mcb; 1 for lightings and 1 for sockets |
