It is not an easy task for people to do work that deals with electrical wire or cable when you do any project in electrical you need to be more cautions, if not that may lead you to risks of shock mainly it occurs when the wiring is done with confusions or when two junctions are wrongly connected which results in poor wiring. However, you need to be more careful while starting any electric work because you never knew how the wiring is done previously? So it is better to switch off the power connection before you initiate the work.
By doing so your safety is ensured if not it may lead to several risks at the same time before switching off the power connection you need to check which wire you need to work on?
You need to do follow the below steps which will help you to check if a wire is live without tester. They are.
- Step: 1 Know the standards – all wiring should be done based on the color coding standards similarly home wire also done based on basic color standards. You can find wires are arranged inside the home electric box as per color coding standards. So while repairing or attempting to fix the fault you should never try to change the wire standard. In residential wiring black colored wire is considered as a live wire it needs to be attached to brass terminal. This connection may change for residential wiring for flat system.
- Step: 2 check the life of electric cables– in order to check whether the cables are in life or not you need to remove the cover of box. You can use screw driver to remove the cover but you need to be more careful while doing that. Because if you touch any wire the connectivity get on this may result you with current passage. You need not to remove wire or touch them to check the conductivity or life of the wire.
- Step: 3 use tester or meter to measure the conductivity rate- after removing cover you can use wire tester or voltmeter to calculate the voltage passing rate. At the same time you need to remember that there is possibility for more wires to have conductivity. in simple way you can check if a wire is live without tester and voltmeter by connecting each wire and check which one makes light to glow and make meter machine to beep.
Manual testing of the live wire without having the meter device
For testing the live wire without having the meter device, you can build your own tester. For example, get a socket and light bulb and attach a couple of wires to it, then touch one to the ground or neutral and another one wire to the test. If the lamp lights then it is live else then test the lamp on live wire like wall socket to make sure that it actually lights.
By following this simple strategy you can check the test if wire is live and before doing this make sure that you wear goggles/glasses and if at all possible keep one hand in your pocket.
