Old Distribution Board and Present Certification

Recently we have been asked to install new cabling from an existing DB board (which is very old BS88 style fuses). I have been told that in order to certify the work then we have to change the DB board.
  • Is this absolutely correct, are there circumstances where you can add cables(s) to existing DB board and ensure your work/modifications are 18th Edition compliant?

  • Otherwise when cabling for new kit was required then installations would have to change DB boards on regular occurrences.

  • I would imagine there are circumstances that this would be deemed not realistic or practicable (which seems to be the expression used).


On this occasion its a 3ph DB board.


Could any of you comment on your experiences in this area please?

  • If it's only one socket-outlet supplied by the circuit, and RCD is not required for other purposes to protect the cable itself, then surely one of those EN 60309 socket outlet assemblies with built-in RCD enclosure would do the trick? They also come in the EN 60309-4 (with isolator) variety.
