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?

    Thanks.  So this is one new circuit . If ADS at the Origin and at this DB are adequate, the DB itself appears servicable , no damage, good IP rating and it will handle any new, additional demand of the new circuit, then no problem. If for any reason you were wanting an RCD on the new circuit, it can go in a separate outboard enclosure , for example.

    Your Certificate will just be for the new cabling, new circuit, making it clear the DB and other final circuits are existing and nothing to do with you. Your Certificate will have just one circuit recorded in the schedules. You will make a comment on the existing Installation; has it been periodically inspected? Does it look a bit unloved ? Generally making it clear that your Certificate is not absolving the existing installation of all its sins. Limiting your liability is the name of the game. The last one in will always get the initial blame for  stuff time expiring if you have not been tight with your detailing on the Certificate .
