This is a new RCD, came in the CU. The max disconnection time I need to comply with is 400ms (Table 41.1 TN ac 230V). From a new RCD I'd expect something roughly in the region of 30ms (for a 30mA fault test). What I'm getting is 234ms (x0.5 there's no disconnection and x5 it's a 13ms disconnection).
TLDR: Meets the regs but a bit ---- compared to expectations.
Replace or use it?
