3.9A的冷氣機.
請問一個插座最大能承受的負荷是多少?
那麼,在上述個案中,我有超負荷嗎?
更新1:
yes,我有check到部冷氣機既config. 因為我部冷氣機系WIDOWS式3/4匹冷氣機, 其他型號--例如分體式/高匹數的冷氣機才需要10A, 更甚者需要12A.我見到其他BRAND既冷氣機最低可以3-3.7A就有3/4匹.
更新2:
我開兩部電腦 照開冷氣機- -"

✔ 最佳答案
一個插座咩插座至得ga~一個小圓腳5A,
220V x 5A = 1100W Max.
一個方腳13A,
220V x 13A = 2860W Max.
一個大園腳15A,
220V x 15A = 3300W
3.9A冷氣220V單相,
220V x 3.9A
= 858W,
加500W的電腦,
858 + 500
=1358W,
一個小圓腳5A吾夠用,
最少13A,15A

I Agree To Physics8801,
My Air-Conditioner Is Using 9.5-10A Within 2 Minutes Of Starting,
The Power Is 2200W,
Why You A/C Using So Low Current(Power)!

除非你架冷氣機係新款既用變流器起動果種，如果唔係，最好分開來用，因爲架冷氣機起動電流會係運行電流既 3 倍 ~ 6 倍，當你架電腦有可能會導致重新啓動，咁如果你有做到一半既工作又未存檔既話，你就會白費心機啦。

The current drawn by your computer = 500/220 A = 2.27 A
Hence, total current from you air-conditioner and computer
= (2.27 + 3.9) A = 6.17 A
Normal power socket in domestic setting can deliver a maximum current of 13 A. Such power socket can thus support the two appliances.
But I wonder whether you have given the correct current for the air-conditioner. A current of 3.9 A in a 220 v domestic power supply only deliver a power output of 858 watts, which seems too low for a normal window-type air-conditioner.
