Why PFC testing is important ⚡ Andrew Duffen and Steve Humphreys explain Prospective Fault Current (PFC) testing, which is an essential live test made up of two measurements: prospective earth fault current and short-circuit current. A fault can travel in different paths, the highest reading is taken and checked against the protective device rating, to ensure it won’t fail under fault conditions. #NAPIT #PFCtesting #ElectricalSafety #LiveTesting #Electrician | NAPIT

Ze and PFC Live Tests In this video Marcus carries out using his MFT tester the external earth fault loop impedance (Ze) and prospective fault current tests. These live tests are carried out from inside the consumer unit (fuse board or fuse box) and will confirm the incoming supply has a connection to Earth and that the overcurrent protective devices can withstand the possible high levels of fault current. Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus
