RCD for outdoor public Car Park high mast lighting

Hi all,

Hope you're doing well.

I'm working on a project where we're installing a number of high mast floodlights and lighting columns (6m high) in a big public car park. I'm trying to determine whether these lighting circuits require RCD protection.

BS 7671 isn't entirely clear on this. It states that lighting accessible to the public requires RCD protection, but it also specifically excludes street lighting, so I'm not sure which category this installation falls under. Also, technically  there's the need to balance the use of RCD against the risk of nuisance tripping.

Have you come across a similar situation before, or do you know how this is typically approached?

Thanks for you help.
