Needing to meet mcb zs with ln loop.
Former Community Member
Where an rcd is relied on for fault protection due to high zs it has been suggested to me that the loop between live Conductors needs to be less than the mcb max zs. I can't find anything on this anywhere but he said he had this confirmed by an niceic assessor. Have I got it wrong ?
The ADS aspect of that socket is perfectly satisfactory, I would say the volt drop is not great though, - if you draw 13A through 0,75 ohms you lose 17V, which you will notice, and is well outside the recommendations for a public supply.
the 0.75 ohms and 300A PSSC are consistent with each other to within rounding errors.
