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

Extending a Ring Final Circuit In this video Marcus looks at extending a ring final circuit so he can add to extra twin socket outlets. The extra sockets could have been feed via a fuse connection unit with a 13 amp BS1362 fuse in it but access to this unit would be difficult. The new legs of the ring final circuit are wired In 2.5 mm2 twin and earth cable (twin and CPC) and connected with Wago 221 connectors. The new connections with be covered over with a blank plate. 🔵How to Test a Ring Fina
