[QUOTE="binky, post: 445710, member: 490"] contravening info, 1 second for ccts / distribution ccts over 32A, but reading GN1, section on RCDs 3.7.7 in my copy, it talks about the actual requirement of TT systems is to restricting touch voltages to 50V. My older version of GN8 (2004) also describes this as being the actual requirement for TT systems and a disconnect time of 5 seconds as[I] inferred[/I] from the appropriate equation. [/QUOTE]
