July 16, 20232 yr How can I tell if this is a TNS or TN-C-S setup? Or does someone know if this is TNS or TN-C-S?
July 16, 20232 yr Good evening MPAD Download the pdf https://www.theforumsa.co.za/documents/SANS10142-1_ED3TC067_SC06_DSS.pdf and look at Annex J Electricity Supply Systems, J.2 Types of LV system earthing there the types are explained with sketches. Kind Regards GerhardK83
July 17, 20232 yr Author Thank you, Does the rectangle in blue or red identify my distribution board? If it is blue, then I have a TN-S connection? If red, then I cannot tell since both figures have a L N PE coming in and i cannot see further upstream?
