Prospective Fault Current PSCC, PEFC, PFC and External Earth Fault Loop Impedance Ze - Live Tests In this video Marcus carries out using the 2 lead high setting on his Megger 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 level

Fault Finding on a Ring Final Circuit How to find fault on a ring final circuit sometime called a ring circuit or ring main. Using a Megger MFT tester Marcus sets about finding an open circuit after carrying out stage one testing end to ends. Marcus show you how to split the ring circuit into 2 radial circuits and then test each leg until you find the faulty socket is identified. Please note there are many different ways to find this type of fault... Electrical fault finding 🔵 How to Test a Rin

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

UK electrician Matt is fault finding on a ring final circuit. The socket circuit is tripping the RCCB inside of the split load consumer unit. Matts identifies the faulty ring circuit and then uses a logical approach to find the part of the ring that has an earth fault on it. By splitting the ring apart Matt creates a radial socket circuit and then sets about getting as many socket on as possible. It is also interesting to see how this older PVC is staring to break down creating green goo around
