Yes, in a perfect world, they would both have separate circuits that were also RCD protected. BS7671:2008 advises placing the upstairs sockets on the same side as the downstairs lights and the upstairs lights on the same side of a dual RCD consumer unit.
What does an RCD not protect against?
A pure RCD can identify imbalances in the currents flowing through a circuit’s supply and return conductors. But unlike a fuse or a miniature circuit breaker (MCB), it cannot provide overload or short circuit protection (except for the special case of a short circuit from live to ground, not live to neutral).
Can you have 2 RCDs in a circuit?
Hi, I have two 30mA RCDs in series, first one as the main switch in the house consumer unit covering all 11 circuits, second one as the main switch on a garage consumer unit, covering three circuits.
