The CU is a Wylex from the early '90s ('91 - 2 IIRC). All MCB, 30mA RCD on rings, cooker, shower etc. and 100mA on lighting circuits. As I'd need 30mA on the lights for the fitting in the bathroom I thought of replacing the two MCBs with miniature Wylex RCBOs, so it's 100mA -> 30mA. I rather like the mini-RCBOs as they are 2-pole. Would this be a valid arrangement (assuming that the RCBOs will actually fit!)?
