Earth Electrode Calculator
Calculate earth electrodes, grounding rods, conductors, and materials needed for your electrical grounding system. Estimate costs for residential and commercial projects.
Step 1: Project Specifications
Soil Resistivity Guide
Low resistivity (10-100 Ω·m): Clay, marshy ground. Medium (100-300 Ω·m): Loam, sandy clay. High (300+ Ω·m): Gravel, sand, rock.
Step 2: Materials & Cost
Material Estimates
Grounding conductor: ~10-20 meters per electrode. Backfill compound: ~25 kg per electrode. Clamps and connectors included.

Resistance Analysis by Soil Type
Earth Electrode Calculation Formula
R = ρ/(2πL) × ln(4L/d)
Where R = resistance (Ω), ρ = soil resistivity (Ω·m), L = electrode length (m), d = electrode diameter (m). For multiple electrodes in parallel: Rtotal = Rsingle/n × (1 + α)
