400v 3P Disboard Distance from Belfast sink

Former Community Member
Former Community Member

Hello all,

Just had a sprinkler valve set incorrectly installed too far to the right on site that prevents a sink being installed to the right of the sprinkler valveset. As such, the solution would be to install the sink to the left of the valveset but this now puts the sink within the proximity of a 400v 3P disboard. Does anyone know the minimum distance that is required to be between the two? We are considering installing a partition to ensure safety however I would like to know what the regulations actually require. Any assistance would be appreciated as i predominantly have a mechanical background. Thanks in advance!

    Exactly what danger do you think is involved? As long as the DB is Earthed, and you may decide to install local equipotential bonding to the plumbing, there is no danger. DBs are usually IP44 unless you cut a big hole in them. There is no regulation to prevent this installation. The Belfast sink is insulating too, but there would equally be no problem with a stainless one. Do you have a copy of the 15th edition, if so it is 30 years out of date? Mike is quite right. Please explain how a shock could be obtained?
