Im suppling distribution circuits and want to use the largest possible RCD available to avoid nuisiance tripping (its for outdoor street furniture and its a TT system). The Ze is 160.
The reg below says 1 second disconnection time but cant find anymore info in the regs about it. Closest I can find is a time delay 150-500 ms Thanks in advance
411.3.2.4 In a TT system, a disconnection time not exceeding 1 s is permitted for a distribution circuit and for
a circuit not covered by Regulation 411.3.2.2.
