shed supply

Eclipse
Guys,

Just some advice please! 

my son has installed a new 6m/m 3C SWA supply to his new wooden shed,( no extranous parts) its going to be terminated into a 4 way consumer unit (RCD main swt) and used to power & lighting in the shed and some lighting in the garden,

question is:

The source end in the house is a twin RCD board, so using a spare way on either side will give the supply cable RCD protection, but what about the RCD in the shed board? is it advisable to keep both?

    Unless the supply is TT, I am sure the local DNO would recommend that the shed has TT earthing, separated from the house. The shed will need its own RCD and rod for this, and ideally a time-delay RCD at the house end to protect the cable (unless it can be done with over current only), otherwise you have no discrimination. 


    Regards,


    Alan.
