- Terminal: 50x6 mm GI strip or lug we…

[8:29 am, 21/05/2026] Espl -Earthingkart: Earthingkart Plate Earthing — Copper & GI

Traditional plate earthing system built as per IS 3043 for reliable grounding 🔩

1. Earthingkart Copper Plate Electrode

- Material: 99.9% pure electrolytic copper plate

- Standard Sizes:

- 600x600x3.15 mm — most common

- 600x600x6 mm — for high fault current areas

- 900x900x3.15 mm — for substations/industrial use

- Key Features:

- Excellent conductivity: Lowest earth resistance due to copper

- Corrosion resistant: Ideal for aggressive soil, coastal, and chemical areas

- Long life: 30+ years with minimal maintenance

- Terminal: 2 nos. copper lugs riveted/brazed for connection

- Installation: Buried vertically at 3m depth with charcoal + salt layers or earth enhancing compound

2. Earthingkart GI Plate Electrode

- Material: Hot-dip galvanized MS plate as per IS 4759

- Standard Sizes:

- 600x600x6 mm — minimum as per IS 3043

- 600x600x10 mm — for better life in corrosive soil

- 900x900x6 mm — for large installations

- Key Features:

- Zinc coating: 80-100 microns for corrosion protection

- Cost-effective: ∼60% cheaper than copper plate

- Terminal: 2 nos. GI lugs welded for strip connection

- Lifespan: 10-15 years depending on soil conditions

- Installation: Same as copper — 3m pit with alternate layers of charcoal & salt or backfill compound

Common Accessories for Both

- 40x6 mm or 50x6 mm earthing strip (Copper/GI) for connection to main grid

- RCC or CI earth pit cover with funnel for water topping

- Earth enhancing compound for <1 Ohm resistance

Standards & Compliance

- IS 3043:2018 — Code of practice for earthing

- IS 3043 Table 7 — Specifies minimum plate dimensions

- IS 1079 / IS 513 — Material specs for copper & MS plates

- Test certificates provided for material grade, thickness, and galvanization

Copper vs GI Plate — Quick Pick

Feature Copper Plate GI Plate

*Cost* High Low

*Life* 30+ years 10-15 years

*Resistance* Lowest Higher than copper

*Soil Type* All types, best for corrosive Normal, non-saline soil

*Maintenance* Minimal Needs periodic checks

For HT yards, telecom, and data centers go copper. For homes and small buildings with normal soil, GI works fine.
