Hi @seneca_maior ,

Replacing the light fitting is relatively simple.

Of major concern however that it is safe for you to do so.

Looking at the picture,there are only 2 wires to connect to the new fitting, so the natural assumption is that one is the Neutral wire and the other is the Active wire which is coming from the light switch.

Working on electrical wiring and fittings can be lethal that is why it pays to make doubly sure that it is safe and never assume that the power circuit has been correctly isolated or that the existing wiring has been installed correctly., e.g. they may have wired the Neutral wire through the light switch and not the Active and therefore with the switch off there is still power at the light. It has been known to happen.

You mention a green/yellow earth wire, but as the old fitting appears to be made of plastic and the new fitting will also be made of plastic, there is nowhere to attach the wire to, which will make the fitting safe in the event of one of the other wires touching the fitting (which won’t conduct that well anyway).

First you need to turn OFF the light switch and then either turn OFF the correct circuit breaker (or remove the correct fuse) in the main switchboard so that there is NO POWER being supplied to the cable which goes to the fitting.

Hint: Place a piece of tape over the circuit breaker to inform people that the circuit is being worked on and therefore not to reset it or if it is a fuse, keep it in your pocket so that it cannot be put back in.

Then you need to CHECK that there is NO POWER on the wires at the end of the cable.

Normally you could use a DMM’s (Digital MultiMeter)- Voltmeter function, to test for any voltage, but since the wire ends of the cable have been barely stripped of insulation, it may be dangerous to assume that there is no voltage there and to strip them further so that you can connect the meter and test for any voltage, e.g. you may not have turned off the correct circuit breaker or removed the correct fuse. You cannot even assume that the earth wire is actually connected to earth and therefore test between earth and each of the wires.

It is better to purchase one of these (or something like it where you are) so that you don’t have to touch a wire or grab both wires at the same time, just use it to touch the bared end of one wire, then the other wire. (with your other hand behind your back ;-). If it shows no voltage on either wire, then you can strip the wires back a bit and connect the Voltmeter -range AC Volts >250VAC - between both wires to doubly prove that it is safe.

After that you can connect the cable to a new Batten mount light fitting (I don’t know what you call them there but it should be something similar) as per the instructions on the packet.

Once you’re satisfied that all is done correctly, insert a light bulb and then go and reset the breaker or replace the fuse and then switch on the light.
