A 2.5 metre deep pit is dug into the ground and a Galvanised Iron (GI) plate is placed inside along with charcoal and sand for the purpose of maintain low resistance around the plate. An earth wire, which is of GI or tinned copper, is bolted to the plate before burying it by means of nuts, bolts and washers.
What are the dangers of ungrounded outlets?
Ungrounded outlets dramatically increase personal and property risk. Ungrounded outlets increase the chance of: Electrical fire. Without the ground present, problems with your outlet may cause arcing, sparks, and electrical charge that can spawn fire along walls or on nearby furniture and fixtures.
Do surge protectors work without ground?
Grounding is a critical element required for proper surge protection.

What is drawback of improper earthing?
Improper earthing-grounding installations can result in equipment damage or improper operation, especially in solid-state equipment. Improper earthing-grounding systems can result in not only electrical injures and shocks, but may have also resulted in electrocution.
What equipment should be earthed?

Can GFCI replace ungrounded outlet?
Answered by Kestrel Electric: You are correct: Replacing all ungrounded outlets with GFCI will elimiate shock and electrocution hazards. It will give you the biggest safety bang for the buck. It will not protect against arching. It will not ground anything.
Are grounded outlets necessary?
A grounded wire is essential because it provides a straight path for that current to travel back to the main breaker panel. House fires are the most common hazard connected to ungrounded outlets. With the ground absent, hazards like arcing inside the outlet will result in electrical sparks, resulting in a fire.
What is the difference between grounded and protected?
Protected means that the surge protector is protecting your equipment. Grounded means that your equipment is properly grounded (which should be required to adequately protect your equipment).
Do 3 prong outlets need to be grounded?
Three-prong adapters are only supposed to be used at properly grounded two-prong outlets. A GFCI outlet will help to prevent electrocution, but it won’t help surge protectors do their job. If this is done, a sticker needs to be applied to the face of the GFCI outlet that says “No Equipment Ground”. 3.
