Hi all earthing systems and understanding them is something we've all had to do in our working lives. One thing that I think makes it harder to get our heads around different systems and the way they are described is the odd way the letter T is used to mean earth why T? Is it as someone suggested from some word or phrase in Latin? I really don't know for sure what I wonder is tho can the IET or whoever is best placed to do it come up with a more sensible lettering system please? The obvious ones are E or G the rest of the letters could be changed too if needed. The whole aim is I have is to make it all more descriptive so that it's easier to keep in our heads what do you think? Hope someone replys X Kelly
Yes, it's T for Terre - from Latin but via French. From what I understand the nomenclature was an invention of the French that was then adopted by international standards and hence back into national standards like BS 7671.
Just think yourself fortunate that the French words for neutral, combined and separated happen to start with the same letters as the English! (I'm not sure other nations are so lucky)
