Hi,
I have asked this before but didnt get a proper explanation but wanted to know why circuits over 32a have a 5s disconnection time but circuits 32a and under have a 0.4s disconnection time on TNS/TNCS (and TT is 0.2s & 1s) but can someone please explain why the longer disconnection time for higher rated circuits or is it because the above 32a circuits are normally fixed loads.
Thanks in advance
