Suburban filling station

lyledunn

This is a new site in a densely populated area. TT 400A TPN DNO supply. The site is pinned to earth by electrodes at various points, several along the wooden perimeter fence you see to the left.

The DNO Tx is immediately behind the metal fence. The whole surrounding area is PME. DNO would obviously not provide a PME terminal but given the proximity of other buildings, is it prudent to consider the site as TT?

    I assume that grey plastic cover is a rod pit, there are two more beyond the lamp post and the lamp post itself is presumably effectively another earth rod.

    Not sure Andy, I am only helping the contractor with the logistics of the installation. All electrodes were placed by others prior to my involvement. I did catch a glimpse of a detailed electrode layout plan on site but didnt get a chance to scrutinise. My interest in all this is nothing more than academic, I have no design input, the contractor is a buddy. I did tell him that he should not have taken the job without detailed design from a consultant or specialist in PFS. Nonetheless, it looks like he has done a first class job thus far!
