Hi All,
My first post on this site so here goes....
Can anybody help....Trying to establish if I would have to change the mec on a TNS system....
Ok So S=sqr(I2xt)/k
When establishing the value of 't' do I use the characteristics of the distibutors main fuse or the main switch in the CU or I have missed the point entirely?
And when establishing 'I' do I use 230v or 240v
Some direction in this matter would be most helpful.
Many Thanks in advance.
