Happy new year folks; just been looking at trip times as i need a photocopy for a client. Anyhow, in the OSG (page 112) for a general RCD, it states "with a leakage current of 100% the device should open in less than 200ms".

However in the BYB (Table 3A, page 318) the table says device should open in less than 300ms!
