[SIZE=10pt]Good afternoon forum members,[/SIZE]
[SIZE=10pt]I’m planning a bathroom refurbishment that will include six devices requiring 230V. A 200W digital shower, a 31W ventilation unit, a mirror with shaver socket, demister pad and led lights (power requirement not specified anywhere), 300W of underfloor heating and two dual fuel towel radiators each fitted with a 150W element. A spare 32A MCB on the RCD protected side of our CU could be used to create a dedicated ring circuit to which the SFCUs (each fitted with a 3A fuse) could be connected. The CU is located in the garage but existing cable routes provide easy access between it and the first floor and loft.[/SIZE]
[SIZE=10pt]The shower’s integrated pump/controller and the ventilation unit will both be mounted in the loft with power provided from two new SFCUs to be located nearby. The problem is that I believe that in order to the safety of local isolation for future maintenance, the four remaining SFCUs should be fitted on the bedroom wall immediately outside the en-suite bathroom door while my wife wants them out of sight, preferably in the loft with the other two.[/SIZE]
[SIZE=10pt]Assuming that they can’t be located in the loft, the spare MCB can be secured in the off position with a padlock, is it acceptable to use this to isolate the entire circuit rather than provide local isolation for each of the six devices? If not and independent device isolation is required, is it acceptable to provide each of the six devices with its own dedicated radial circuit via a new secondary consumer unit populated with six 6A (3A appear to be uncommon) MCBs plus RCD or six RCBOs?[/SIZE]
[SIZE=10pt]I’m aware that the electrician will answer these questions but we don’t intend having the work started until summer and would prefer to understand the aesthetic implications now. Apologies for the length of this posting - I did try to keep it as short as possible - and thanks in advance for any advice or recommendations.[/SIZE]
