What are peoples views/practice on a double pole RCBO board for a TT installation. Do you install an up front time delay RCD separate to CU or in place of main switch, in my example the tails less than 1m? Got my head in the book but am none the wiser. Cannot see the wisdom of protecting the tails, then in the process leaving tails coming out of the remote time delay RCD to the meter where there is little chance of damage?
