24 volt DC FELV equipment installed in a location containing a bath or a shower.

Sparkingchip
Once again I’m reviewing options following on from another Discussion that includes the use of 30 mA SRCD and FCURCD devices.


I am reading the OSG and also BS7671 411.7 Functional extra-low voltage (FELV) as well as section 701.


Am I correct in thinking that 24 volt DC FELV equipment installed in a location containing a bath or a shower supplied from outside of the room from say a controller with a transformer mounted in an airing cupboard needs 30 mA RCD protection, because FELV does not provide the same level of protection as SELV and PELV.

    I have emailed the manufacturer to ask them.


    There is no doubt that if the 230 V supply is taken into the shower room a RCD is required, but if that is outside of the shower room and all the cables are 24 Vdc supplied by the FELV transformer I think it still needs 30 mA RCD protection, so I install it. 


    I am just checking I am not going over the top and gold plating jobs.
