I would also be doing everything I could to rcd protect the armoured.
I agree about protecting the submain, but you don't want an RCD at source (Why?) as it would/could trip the whole of the remote installation on an earth fault which is a good 30 M away !, no, RCD's local if required is far better IMO, besides if the RCD was at source would this not contravene the regs wrt circuit segregation ? (314.1).
Unless of course the Installation was TT, and then a time delayed 100mA may be required
