Hotel External Lighting - RCD

Apostolos

Good afternoon

We have some bollards and lighting columns at the backyard of a hotel

We are feeding them with XLPE/SWA/LSF cables through ducts.

Do we need RCD protection at the board?

I am looking into BS7671 section 714 - OUTDOOR LIGHTING INSTALLATION and there doesnt seem to be anything to indicate an RCD apart from a telephone kiosk, bus shelter, advertising panels and town plans.

Do I read it correct or having a steel column makes a difference and I do need an RCD?

I wouldnt normally ask however I remember in the past people in here pointing out that the external lights need RCD and refer to some BS7671 clause but my memory isnt that good

Thanks

    Basically as I understand the principle behind this....ANY metal furniture/electrical item outside that can come in contact with public should be under RCD.

    That could be read as including steel street lighting columns, roadside communication cabinets, outdoor units of air conditioning systems, even outside taps bonded to the MET via metallic pipework - which might be a bit OTT.

    Hi Andy

    Have a look at my original reply

    The following are excluded:
    5. Street lighting and traffic signage
    6. Illumination of monuments
    7. Platform lighting at rail/bus stations.

    yes - but you need to understand why that is - it is the balance of risk due to tripping off with a non-fault vs the risk of staying on with a real fault. Then you can work out which list any other item should be added to.
