hi, I am an apprentice learning to do a bit of testing and am wondering if you could please help with a few boxes I am struggling with on a condition report as below.
1.nature of supply parameters- taken at the board, can my prospective fault current be 587A( result given at same time as earth fault loop impedance)
2.details of rcd main switch- difference between current rating( this time is 100A) and the 'fuse/device rating or setting'
3.details of red main switch-cannot find the 'rated time delay'
Thanks in advance
