    hello need to inquire about showers. are you supposed to have a rcd when installing an electric shower or is the 40A mcb suffisent protection in the event of a fault?

    Under the 16th edition an RCD is not required but recommeded due to electricity near water. But in the new 17th all circuits in a bathroom must be protected by one or more RCD/RCBOs.
    Myself i would not install a shower without a 30mA RCD in the circuit.

    As far as i am aware and i know i will be corrected if wrong... but under the 16th edition there is no requirement to install on a RCD. Although it is good practice to install them on one. (As I do)

    ;)

    as said before,you dont need rcd protection for the shower if the install is under the 16th edition.bs7671 is only a minimum standard though.you wont get a spark to say not to use an rcd with this in mind.

    its up to you(or your spark)but i wouldnt.

    External RCD in an enclosure?

    It's normally manufacturers recommendation to fit an RCD to a shower circuit (16th) and not that of the wiring regulations.

    No idea, they may do..
    Can you fit a small 2 way board to the side with RCD. More work but worth it. Its up to you. I would, but like we said there isn't any requirement. So do it before july if u don't want to fit one..
