Old Distribution Board and Present Certification

Les Spiteri
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?

    We are designing a control panel that controls motors on this site, the control panel will be fed from this DB board.

    The team responsible for installation of "fixed wiring" said the DB board would require replacement if they were to run a cable to our new panel in order to certify properly,


    We only require a single 3ph cable to be fed from the DB board, seems to me the to change a DB board for a single cable is unrealistic, but if thats the rules.......
