I have an FCU with very short lengths of supply cables and this will present an issue with replacing this FCU as it has a crack. Can you please advise on the recommended approach to extend these cables as there is no slack. Also, can I replace old cable colours with the new ones as I only have the new colours for the extension cables?
Finally, is there a guide on how much cable there should be behind the back of a socket to make maintenance easier?
Thanks in advance.
