Commonly used on BNO installations from the Ryfield board to a series 8 Head fitted with a solid link red head for meter isolation. Surface run cables only for the unmetered supply to a local cut out with a red head solid link with the neutral and earth separated. It is still TN-C-S on the incoming supply cable but the neutral and earth split on the BNO network to comply with BS 7671.
