Yes. Earthing is not an optional extra in a home or building. Indian wiring practice and electrical safety regulations require it, and for good reason: it is what stops a fault inside an appliance from becoming an electric shock.
What earthing does in a home
- It keeps the metal bodies of appliances safe to touch if a wire inside comes loose.
- It lets the MCB or RCD in your distribution board detect a fault and switch off the supply.
- It protects inverters, UPS units, computers and televisions from surges.
- It is essential for rooftop solar systems and for any lightning arrester on the building.
Signs of poor earthing
- A tingle or mild shock when touching a geyser, washing machine, refrigerator or metal tap.
- An RCD or ELCB that trips often without an obvious reason.
- Electronics failing more often than they should, especially after storms.
- An earth pit that has not been checked for years, or a pit cover that has been buried or lost.
How many earth pits does a building need?
It depends on the load, the soil and what is being protected. A house typically has at least two earth electrodes, and larger buildings, apartment blocks, lifts, generators, solar plants and lightning protection systems each need their own earthing, bonded together as the design requires. An electrician should decide after looking at the site.
Old pits and new ones
Many older buildings still rely on pipe or plate earthing with charcoal and salt, which needs watering and loses effectiveness as the salt washes out. Replacing or supplementing these with chemical earthing electrodes and backfill compound gives a lower, steadier resistance with very little upkeep. Each pit should have an inspection chamber with a C.I or FRP pit cover, so it can be tested.
What to do next
If you have any of the warning signs above, have the earthing tested by a licensed electrician. If new pits are needed, we supply the electrodes, compound, strip and covers, and we can install and test them for you. Contact us with your location and building type.
