EICR Fault Finding on Sockets - Reverse Polarity & High Resistance - Ring Final Circuit Testing

During an EICR on a ring final circuit (sometimes called a ring main or socket circuit) Matt discovers high resistance on 2 sockets during the figure of eight test and incorrect polarity when live. Matt finds and corrects the fault before testing the circuit the circuit again.

Note - this is a snap shot of the work carried out and is designed to raise questions and talking point in Matts classroom lessons.
