Best House Lighting Circuit

A lighting circuit can serve up to 12 x 100w bulbs.

House lighting circuit. Control of a lighting circuit from two points a and b. Once you have mastered the basics we take a look at the two way switch arrangement. A single 5 6 amp circuit can cope with up to twelve 100 watt lamps it is usual in a multi storey house to have at least one lighting circuit for each floor even if the number of lamps are less than 12 on each level.

Solar powered home lighting system circuit fig. Each house should ideally have at least two lighting circuits. The cable leaves the consumer unit and runs to each outlet position before terminating at the last fitting on the line.

The circuit is built around microcontroller pic16f877a ic1 two 80w solar panels connected in parallel at con1 two 12v 80ah batteries batt 1 and batt 2 and a 16 2 lcd. Multi point loop in radial lighting circuit the light wiring diagram shows how the live feed from the consumer unit fuse board shown in blue in fig 1 feeds into the first ceiling rose ceiling rose a fig 1. As you can see a basic lighting circuit consists only of three components.

This is usually a distribution board of some sort. This would be cable a in the diagram below fig 2 which shows how the ceiling rose is terminated. If you have longer lengths to cover 1 5mm squared cable can be used and the maximum length allowed using this is 110m.

In order to energise the light we need to connect it to the supply available. Using 1mm cable is allowed for up to 95meters of circuit length. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit.

This does not include the light switches which should be wired in switch wire which contains 2 red cores. Sometimes called a loop in circuit this shows how power is distributed around the lighting circuit via the ceiling roses or junction boxes and how to wire a light switch into the circuit. This type of circuit is used in hallways rooms with two entrances stairs bedrooms e t c.
