earthing check with multimeter

why earthing needed home?

faluty current in home appliance

Earthing is necessary in a home to protect people from electric shock by providing a safe path for any fault current to flow directly to the ground,

Buld test

Eath & Live  = Buld no dim or flicker   earth is good, dim or flicker faulty earthing  NO light no earthing

Right Hole >>  electrical or live, left hole nutral , upper earth

Multi meter test

generally in india 240-250 voltage so we set 600volatage on multimeter  (750v in some generally 250+ above)

try earth + neutral volts = not more than 5v

eaarth+ live = 240 (which should same as on nutral + live with may little diffrence upto 2-5volts).

generally in india right side >> live/current/

left side: neutral>>

you can also use tester which is light turns that is live/electrcity.

Connect the test leads to the circuit: black lead first, red second. Note: ac voltage does not have polarity.

On a multimeter, the red lead is considered “live” or positive, meaning it should be connected to the power source or the higher voltage side of a circuit when measuring voltage.
Key points about multimeter colors:
Red: Positive (live)
Black: Negative (neutral)  or eathing

earthing test with multimeter

red into netral which left side of scoket, earth upper black hose.. not more than 5 volts difference. ideally same.

Reading interpretation: A low resistance reading (close to zero ohms) indicates a good earthing connection.

when i put 200v its indicating 0.08 when i put 700v it indicating 0.01

(insert into live & neutral and insert into live & earth it should be same or difference not above 2-5 volts.)

Red on v, Blac on Com

Red intor netral portal which is bottom left  >>

Black in earth port upper  >>

if reading more than 3 volts , if there is overload  it can go 5 volts, maxium allowed voltage between neutral and eartn not more than 5.

(live to neutral) from the second (live to earthing). After solving that, add the number of volts from your third reading (neutral to earthing). If the number is greater than 2 V, then your earthing may be faulty. Otherwise, the outlet is safe to use.

• For example, if your first reading was 230 V, the second reading was 231 V, and the third was 0.5 V, then your formula would be (231-230) + 0.5, which simplifies to 1.5 V.

which side is live on a socket

Rigtht = postive / live

Left= negative /

should i maintain ground earth

Yes, you should definitely maintain your ground earth (also called earthing) as it is crucial for electrical safety and reliability, and a poorly maintained ground can lead to potential hazards like electrical shocks and equipment damage; regular checks and maintenance are essential to ensure its effectiveness.

• Inspect connections:

  Check all connections within your grounding system, including those to ground rods, electrodes, and conductors, for corrosion or looseness. 
• Address corrosion:

  If corrosion is present, clean or replace corroded components to maintain good conductivity. 
• Environmental factors:

  Consider the environmental conditions where your grounding system is located, as factors like soil type and moisture can affect its effectiveness.

Can i pour water on earthing

can i make garden on earthing

Yes, you can absolutely create a garden on top of an earthing system (grounding rod), as long as you are not directly touching the metal rod itself; planting around a grounding rod is perfectly fine and considered a form of “earthing.
