The first thing to do is to run a length of cable from the supply (distribution board) to the light itself. DO NOT connect this cable to the live supply! This must only be done after the whole circuit is finished and fully tested to comply with BS 7671. This project involves installing a new branch circuit, which consists of a dedicated circuit breaker, the cable run, and the final connection at the switch. In this Video you will learn how a DB is wired, I cover Circuits Breakers, Earth Leakage, Earth and Neutral Bars, and more. In this Video I will demonstrate how to wire a DB according to the previous Video. In this video you will learn. Wring a simple lighting circuit might be an easy enough process for a qualified electrician, and with a little determination anybody with basic skills can do it. First let's have a look at this wiring diagram describing a lighting circuit in its most basic form: As you can see, a basic lighting. Although a 5A junction box is suitable for a lighting circuit (even if on a 6A circuit breaker), it is generally much easier to use 20A types. It covers essential safety features, grounding requirements, and the identification of conductors in residential electrical systems. Typical 120V branch circuits.
