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

    Absolutely right AJ. I assumed that in the OPs case the MCBs were set on to a bare busbar. If not, andIP2X or IPXXB is in place then no issue. 
    That being the case, I would have no issue with any aspect although I concur that the absence of 30mA RCD required by 7671 is worth further consideration if one was setting out a design. In that regard, where the luminaire is mounted below 2.8m, IS10101 requires that due regard is given to the failure of the illumination in terms of slips, trips and falls and, as a minimum, requires the circuits to be sub-divided.
