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!

    BS 7671 does not specify a minimum height or horizontal distance.  However, Regulation 512.2.1, relating to external influences, requires that equipment shall be of a design appropriate to the situation in which it is to be used or its mode of installation shall take account of the conditions likely to be encountered.

    Regulation 522.3.1 requires a wiring system to be selected and erected in such a way that no damage is caused by condensation or by ingress of water whilst being installed, used or maintained.

    When installing standard accessories, good practice would be to install them at least 300 mm horizontally from the extremity of the sink bowl (excluding drainer) or wash basin opening. 

    For commercial premises, the same principle applies.  However, the designer may consider it appropriate, due to the increased risk of splashing or the use of water jets, to install equipment that has a degree of protection of at least IPX4 or IPX5 respectively, as appropriate.

    If an accessory is encountered closer to a sink than this during a periodic inspection, engineering judgement will need to be applied to determine whether this is safe. An accessory so located for a considerable time that had not suffered any perceptible water ingress or damage would not warrant a classification code or comment on the Electrical Installation Condition Report.

    General guidance is to avoid positioning a consumer unit immediately above or alongside a sink.
