Is not about voltage, is about Watt, aka power.
Opinion: Maximum power voltage per port, need help!

QUOTE(zeese @ Nov 4 2011, 03:18 PM) i think, the accurate way is to look at the current (ampere). If it is above 13A, your plug fuse will burn. If it is not burn, the DB fuse will switch off. If it doesn't switch off, the house will be on fire... 13Amp usage will not burn the fuse, most fuse have some extra tolerance. Is not digital fused. MCB is usually 15Amps for socket. IT won't trip too.So, current (A) = power (Watt)/ voltage (240V). Add up all current consumption from each appliance in order to see whether it is overloaded or not. By the way, please don't take my word. I'm hoping someone can tell me whether what i'm saying is right or not..

If its not motor / compressor load just sum all up. Say your equipment A is 1000Watt, equipment B is 1000 Watt, Equipment C is 500 Watt. This only use 10.5Amps (using 240Volt). So is technically withing the limit. but how?! advisable or not? who should i check with? But ideally in real life we don't connect to many high load equipments in once socket or don't stress to the limit. Because you don't know the condition of the socket, your quality of extension, and wires.. This post has been edited by weikee: Nov 4 2011, 04:29 PM |

QUOTE(FreddieKam @ Nov 4 2011, 04:31 PM) so in that sense, do u think a fridge can share the same point with a hood (not on 24/7) of course.. Check your hood and fridge power rating (Watt, or Kw)im jus afraid of overload tat is very dangerous Added on November 4, 2011, 4:36 pm QUOTE(mengsuan @ Nov 4 2011, 04:31 PM) Max 3600W by standards 3600Watt / 240V = 15 Amps, that is really the threshold. Do remember sometime voltage can drop to 230v, that increase the current.And to really use 15Amps, you need the round socket. This post has been edited by weikee: Nov 4 2011, 04:36 PM |
