I am having to run a large SWA feed cable to a fixed load (45Kw TP). The cable will be run externally but above ground on cable tray.
Do I need to provide RCD protection for the SWA cable at the distribution board end??
 
@OP, read up in the regs about the requirements for rcd protection in all situations then get back to the thread would be my advice.
 
Just posted another question on the site relating to the earthing system at some new distribution boards on the site - maybe you could check that one out??
