Exported PME to steel floodlight columns, public tennis courts

Patrick Hammond

Hi

We're doing an EICR at a local tennis club. It has a number of  3 phase floodlights mounted on galavanised columns illuminatimg outdoor tennis courts.

They are earthed via an exported PME TNCS system which was surprising because we'd imagined they would have sunk an earth rod at each column and not exported the PME.

The location is open to the public. Circuits not 30mA RCD protected foir additional protection.

I'm no

Many Thanks for your help

    Thank you everyone and this has been a really useful thread for me. As way of a post script I spoke to NIC tech today about this. 

    Just to answer an earlier question, the light supply is not direct from a DNO and is distributed via the 3phase feed at the club house

    Some debate about whether it was in the excluded from list of public lighting that needs the 30mA RCD but the only exclusion that came near was street lighting and traffic signage. Obviously not that, so was deemed to be spaces open to the public so required additional protection. I think we can agree on that?

    Other debate as hilighted by Mr Jewsbury was would the light high on top of the column be accessible to the public, however we quickly agreed that the metal column had to be included as part of the light. 

    What we couldn't decide was the EICR code. C3 improvement recommended because the installation met the regs at the time it was installed  (10 years ago) or a C2?

    One none compliance that nearly passed me by and (had to read it twice) was 714.411.201the door in the street furniture used for access not to be used as barrier or enclosure. This installtion had an unenclosed din rail with MCBs screwed to a metal plate in the column, so C2 for that anyway.

    This has been a learning journey , thank you and now we are going to become  floodlight specialists just to annoy David Stone

    Cheers Pat
