Electrical earthing (grounding) is essential for safety in any building. Proper earthing protects against electric shocks, equipment damage, and fire hazards by providing a safe path for fault currents to flow into the ground.
Why Earthing is Important
- Personal Safety: Prevents electric shock to humans
- Equipment Protection: Protects appliances from damage
- Fire Prevention: Reduces electrical fire risk
- Lightning Protection: Dissipates lightning surges
- Stable Voltage: Maintains consistent voltage levels
Types of Earthing We Install
Pipe Earthing
Galvanized iron pipe driven into the ground. Most common for residential use.
Plate Earthing
Copper or GI plate buried in the ground. Good for commercial/industrial.
Rod Earthing
Copper or GI rod driven into soil. Quick installation.
Chemical Earthing
Modern maintenance-free earthing using chemical compounds. Ideal for rocky soil or areas with high soil resistance.
Earthing Installation Process
- Site assessment and soil testing
- Dig earthing pit (appropriate depth)
- Install earthing electrode (pipe/plate/rod)
- Add charcoal and salt layers
- Connect earthing wire to electrode
- Run earthing wire to distribution board
- Connect to all circuits and appliances
- Test earth resistance (should be <5 ohms)
Earthing Costs
| Type | Price (PKR) |
|---|---|
| Pipe Earthing (GI) | 8,000 - 12,000 |
| Plate Earthing (GI) | 12,000 - 18,000 |
| Copper Rod Earthing | 15,000 - 25,000 |
| Chemical Earthing | 18,000 - 35,000 |
| Earth Testing | 2,000 - 3,000 |
Signs of Poor Earthing
- Tingling sensation when touching appliances
- Frequent electric shocks
- Appliances tripping ELCB/RCD
- Fluctuating voltages
- TV/computer showing interference
