There is a simple technique by which one can check if earthing at home is working properly.

1. Take a bulb with a holder connected with two wires

Simply connect a bulb to a lamp holder with two cables as live and neutral and open the main switch where your earth wire is connected then put one of the wire to the earth bar and the other to a live wire bar of the main switch, the bulb will light up if the earth is effective since its grounded it’s also acts as a neutral but it’s effectiveness as a neutral is minimal as compared to the neutral from the substation. So, this is the simplest way to test your earth at homes but you must also check if this earth is being distributed to your power sockets and all the lighting systems.
