Old multi point radial lighting diagram using junction ...
Fig 1 shows what is referred to as a radial circuit (sometimes called a 'loop in' or 'multi point radial lighting circuit'). which uses junction boxes instead of ceiling roses. You may find this wiring arrangement in older properties.lighting wiring diagram | Light wiring
The first reason this is BAD is on safety grounds; say we are working on the light upstairs, so we turn off the upstairs lighting circuit thinking we are safe..WRONG.The live is picked up downstairs and there are still live conductors feeding the switch upstairs and if someone flipped the downstairs switch in this diagram that live feed would extend all the way to the lamp too (you’re fried ...Ring circuit
In electricity supply design, a ring final circuit or ring circuit (often incorrectly called a ring main or informally a ring) is an electrical wiring technique developed and primarily used in the United Kingdom.This design enables the use of smaller diameter wire than would be used in a radial circuit of equivalent total current. The reduced diameter conductors in the flexible cords ...House Wiring for Beginners DIYWiki DIY FAQ
Radial circuits are used for lighting.There is one lighting circuit on each lighting MCB.Lighting circuits are usually on a 6A MCB or 5A fuse, though 10A can be used (with some extra restrictions (now removed in the 17th edition of the wiring regs)) for large circuits.However if the area served is large, more 5A or 6A circuits would in most cases be preferable.Fuse (electrical)
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and it must be replaced or ...200W Leach Amplifier – Circuit Wiring Diagrams
