3 Phase Prospective Fault Current Tests - PFC Live testing for prospective earth fault current PEFC and prospective short circuit current PSCC (PFC tests). These tests are demonstrated on a live 3 phase distribution board and will help with AM2 and AM2S exams. We use the rule of thumb for calculating the PSCC test by taking the highest reading form the line and neutral tests and doubling it and then we go on to show you how some instruments can measure PSCC between line conductors. As always pre
