RCD

[bs_5354]

  我有個circuit是給电腦柜用的. 用IEC309插頭circuit. 电力絛例是否要求要加RCD?
其實現時啲data center是否多數唔會獨立加RCD俾每一way circuit, 而當個电腦柜係fix equipment?

多謝指教.

你都識得講係插頭及插座，按COP是要加RCD。
不論是IEC60309、BS196、BS546、BS1363。
為避免RCD跳掣，很多時會獨立加RCD俾每一way circuit。
當然，一樣有很多人不加RCD，但不代表合乎COP之規定。
但若該處祗容許受過訓練之員工進入，
有足够之標記及告示指出沒有RCD作保護，
房產擁有人盡可能避免意外的發生，
或許可以用法例的灰色地帶，
但不要話係我講，自己執生

So if I do not use IEC309 socket for the computer equipment rack, but use a fixed power connection, I can omit the RCD. Right?

bs 5354 工友：

請參考守則 26O 寫得好清楚。

如果你仲唔放心一定要裝漏電斷路器，就要裝 (RCBO) 有條功能接地導線嗰隻。

1.RCD--RESIDUAL CURRENT OPERATED DEVICE
2.RCCB--RESIDUAL CURRENT OPERATED CIRCUIT BREAKER
3.RCDO--RESIDUAL CURRENT OPERATED DEVICE C/W OVERCURRENT PROTECTION
4.RCBO--RESIDUAL CURRENT OPERATED CIRCUIT BREAKER C/W INTEGRAL OVERCURRENT PROTECTION

Dear Gentleman (bs_5354),

I believe that your concept is correct. The computer equipment is become a fixed electrical installation with permanent connection to the LV power system. Therefore you do not install RCD to protect it if the E/F Loop impedance is lower enough to match with O/C protective devices. Say 0.4Sec or 0.2Sec inside/Out of "Equal Potential Zone" respectively. Right!

Please feel free to correct me if I am wrong!

Best regards,
