How to Check Earthing at Home with Test Lamp and Multimeter
Learn How to Test and Check Earthing at Home with Test Lamp and Multimeter
We all must know How to Check Earthing at Home with Test Lamp and Multimeter in order to be safe. Proper earthing at home ensures safety in case of electrical shock. Checking value / voltage of earthing in home electrical socket is very easy. We can check if earthing is proper or not using a Test Lamp or a Multimeter. Let us learn in detail.
What is a Test Lamp?
A Test Lamp is a Florescent Bulb connected to a Holder and Electrical Wire. Most electricians use Test Lamps as a voltage tester to check Earthing and other electrical connections.
What is a Multimeter?
A Multimeter is a measurement instrument designed to measure electric current, voltage, and resistance over several value range. Check – How to Use Multimeter
How to Check Earthing at Home with a Test Lamp
- Insert the Positive Wire of the Test Lamp in the Positive side (Right Hole) of the Socket and Negative Wire to the Negative side of the Socket (Left Hole).
- Switch ON. The Bulb will Glow at Full Brightness.
- Remove the Negative Wire (Leave the Positive Wire as it is).
- Insert the Negative wire in the Earthing of the Socket (Top single Hole).
- The Bulb must Glow with Full Brightness as before.
- If the Bulb does NOT Glow at all then there is NO Earthing / Grounding. If the Bulb Glows Dim, then it means the Earthing is Not Proper. Get it checked by a Professional Electrician.
How to Check Earthing at Home with Multimeter
- In case of AC Power supply, keep the Pointer of the Multimeter at AC Value above 250 Volts. In case of DC, Keep the Pointer at a DC Value above 120 Volts.
- Insert the Red Probe in the Positive Hole of the Socket (Right Home) and the Black Probe in the Negative Hole of the Socket (Left Hole).
- Check and Note down the value.
- Now Remove the Black Probe and insert in the Earthing Hole of the Socket.
- Read the Value. It must be same as earlier.
- If there is NO Value of Less Value then the Earthing is not Proper.

What equipment do I need to check earthing?
You will need a digital multimeter, test lamp, water, a metal rod, and test wires.
How do I perform a basic earthing test?
Insert the metal rod in the ground near the earthing point, connect it to the ground port of the multimeter. Use the test wire to connect the earthing point to the multimeter's live port. A reading close to zero indicates good earthing.
What should I do if the earthing test reading is high?
High readings could indicate poor earthing. Check connections, moisten the area around the rod, and ensure the rod is deep enough. If issues persist, consult a professional electrician.
Can I perform earthing checks without a multimeter?
While a multimeter is recommended, you can also visually inspect earthing connections for rust or damage. However, a multimeter provides accurate measurements for better safety assessment.

Hello Mr. Das I’m Maitha from Dubai and I’d like to ask if you can give online classes regarding electronics, the components , what they are used for and formation of PCB
Sorry, I am too busy.
This is a terrible practice, by doing this your differential switch will sense your bulb as a huge leakage current. Possibly leaving your whole neighbourhood out of electricity. The same happens for the second test you propose, most multimeters with relatively low input impedance, in voltage measurement, will draw some current to earth. causing the same issue as before. Which would be a proper approach for earthing testing? Thanks
I understand it to some extended thank you but my cosine is if I text with texting lamp earth is more brighter than lives and neutral
Please if you have any other advice to give me please try thanks
Useful
Hi sir, if your system is protected with a differential circuit breaker, it will detect your test lamp once it’s connected to the earth as a fault. Thanks
I would like you to send me a wiring diagram so as to convert my 6 Fluorescent tubes with ballast ant Stater that i have in my garage to an LED
Thanks alot
Looking forward to hearing from you
Nice one I enjoy and understand the feedback
