Magical 1.67 - Ring Circuit Testing If you wire a ring final circuit in 2.5mm2 twin and CPC cable (twin and earth) the relationship between the resistance of the live conductors and the CPC is a multiple of 1.67. 🔵 full video - How to Test a Ring Final Circuit - Ring Main or Socket Circuit - Ring Continuity & Polarity Tests https://youtu.be/UesYHVsZD-E #testing #electricaltesting #apprentice #apprenticeship #electricaltraining #ringcircuit | GSH Electrical Training

The ring final circuit (ring main) is a unique British socket wiring system. More complex to test and install compared to radial circuits. In this electrical tutorial, Joe Robinson explores how the current flows in the branches of a ring circuit. This video demonstrates why you can't use a 16A junction box on a 32A ring final circuit, a topic explored in a previous electricians' Q&A - https://youtu.be/LreZCnItWfM 🕐 TIME STAMPS 🕕 ====================== 00:00 Ring final circuits - (yes loads of

EICR Ring Circuit Fault Finding Issues - Testing an Open Ring Circuit & Low Insulation Resistance On site with electrician Matt testing and fault finding whilst doing an EICR (electrical installation condition report). This video will be used to support classroom teaching at college. Matt highlights issues with the ring final circuit (ring main) open ring test end to end and low insulation resistance test. NOTE - Some further discussion have been left for the classroom lessons. This video gives
