RCD for bathroom electrics?

    IIUC an RCD is required for all bathroom electrics. I have a japanese-style power bog, and electric underfloor heating that i want to install (tot. <2kW).

    Was planning to add a RCD protected fused spur to the existing ring main and just connect both appliances to that. But the ring main already has an RCBO on it. Additionally the toilet comes with a separate RCD on its power lead.

    Seems that a few threads on the internet suggesting chaining RCDs isnt a good idea (they can set each other off) - so am i best off just relying on the RCBO in the consumer unit, and not using any other dedicated RCD for the appliances?

    I'd say just stick with the rcbo, as long as it's up to the load current involved and that it's 30m/amp trip.

    rcbo on the ring main is a 32A/30mA wylex - so assume that is fine?

    The Wiring Regulations require the circuit supplying the location to be protected by a 30 mA RCD, your circuit is protected so that’s okay.

    No need for additional RCDs.
