Are RCD's Required?

Nano Brewery
Hi, looking to understand if an RCD would be a required regulation (and/or just highly recommended) in the following situation.  The additional cost of installing four or five 3-Phase RCDs is quite substantial and I would prefer to avoid it if still deemed as safe and not legally required.  Earthing system is TN-C-S.


For connecting up 4x Immersion Elements (9kW, 9kW, 6kW, 3kW) in Brewery Tanks I am looking at either:


A.  SWA Cable clipped direct to basket from the Control Panel to IP rated Plugs/Sockets mounted on the wall.  Then floating SY Cable (recommended by electrician) from the wall to the Tanks, which is about a 2m run.  Thinking Plugs/Sockets just to make life easy if I ever want to move things around and also for easier access for cleaning.


B.  Same as above but swapping the Plugs/Sockets for Isolators.


Look forward to your feedback and opinions.  Cheers.

    Higher current ones do exist that would do, (63 amp example) but not in great numbers or variety or indeed from the famous names.

    An RCD incomer and followed by  MCB protection might be easier to source the bits for.
