Testing and Fault Finding - Low Insulation Resistance Fault - Testing at 250 and 500 Volts DC It isn't often that you can carryout the insulation resistance test will all circuit connected because of RCD protection in a consumer unit. In this video Marcus has no RCCB's or RCBO's in the consumer unit (fuse box) so he can test between all line conductor to the neutral bar, all line conductor the the earth bar and between all neutral and earth connections. Marcus shows how using 250 volts DC from h

Fault Finding Testing for Insulation Resistance. Low Reading Insulation Resistance Fault How to test for insulation resistance inside a consumer unit. Marcus is carrying out an electrical inspection and testing when he come across a fault giving him a low reading during the insulation resistance test. These videos will help with AM2, AM2S, AM2E and your apprenticeship end point assessments. The testing and fault finding is carried out with a Megger MFT tester in controlled conditions at Tresham
