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
