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

3 Lead RCD Test in the Consumer Unit on RCBO's Saving Time During the Live Testing's Process Student training aid for testing an RCBO rated at 30mA using a MFT Megger tester. Includes a full demonstration of how to test the RCBO using 3 leads from with the consumers unit. Note my default position is always 3 lead testing as it’s my preferred method of testing for Earth Fault Loop impedance when RCD protection is present. 2 lead tests can also be carried out for both testing RCDs and circuit Impe

First Live Test - Check Polarity of 3 Phase Supply, Using an Approved Voltage Indicator AM2 & AM2S First live test according to BS 7671 is check polarity of the supply with an approved voltage indicator. For AM2 and AM2S the 3 phase distribution board will need testing to prove the incoming 3 phase supply polarity. For this test I used a voltage indicator and proving unit I explained in the video my thinking behind my use of the proving unit as it is not necessarily required. As always preparing

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
