I'm just building an en-suite into our bedroom. My electrician says that ALL circuits in the room (lighting, shower, shaver socket, extractor, towel rail) need to be on a stand-alone RCD outside the room. Relying on the RCD in the consumer unit is not enough. Is he correct? An RCD is an ugly thing to have on a wall
All circuits should be on an RCD, but this can be at the consumer unit. Perhaps only some circuits are currently protected? In which case, protect them at the CU. photo of CU?
Many thanks for taking the time to respond. It's quite an old CU. It's not even split. EVERYTHING is on a single RCD (although the various circuits do of course have their own MCBs). Lights, sockets, kitchen circuit, the lot - all protected by a single RCD. Hardly to modern standards but since everything is RCD protected, do I really need an additional RCD to cover the en-suite? I plan to have the CU replaced later this year so that each circuit is protected by an RCBO. Will that also negate the need for a dedicated RCD for my en-suite?
Lets see a picture of the consumer unit and RCD. But, basically, if there is a 30mA RCD covering the whole installation then you do not need another one. It would be pointless. Good plan to have an all RCBO board. We like that!
Looks like the whole board is rcd protected, provided it's 30m/a there's no point in adding another rcd.
