714.411.3.4 Additional protection
Lighting that is accessible to the public shall have additional protection by an RCD having the characteristics specified in Regulation 415.1.1
Examples include:
1. Gardens, spaces open to the public
2. Telephone kiosks
3. Bus shelters
4. Advertising panels and town plans
This list is not exhaustive.
The following are excluded:
5. Street lighting and traffic signage
6. Illumination of monuments
7. Platform lighting at rail/bus stations.
In view of the above quoted regulation, it could be argued that RCD protection is needed for certain types of car park lighting, especially bollards, which are easily damaged by cars and vandalism. However, in terms of coding for an EICR, a judgement would have to be made by the inspector, based on the assessment of the risks to the public. I can't help but relate this to the infamous pub incident a couple of years ago, where RCD protection could well have saved a child's life.
