Regs state (Page 64 of latest edition) that Table 41.1 shall be applied to final circuits. But it then talks of RCD protection being used to satisfy these maximum times.
If we're testing the RCD not the MCB's why is it mentioning which circuit is being used? We're supposed to test the outgoing side of the RCD so there shouldn't be a circuit to test.
Any help appreciated.
