Product Overview
Green Yellow Earth Grounding Cable Wire 10-25mm² is a single-core copper conductor PVC insulated earth/grounding wire with the distinctive green-and-yellow stripe insulation that is internationally recognised as the protective earth (PE) conductor colour per IEC 60446. Manufactured to IS 694, CENELEC HD 21, IEC 60227, BS 6004, and DIN VDE 0281, this wire provides the essential safety function in every electrical installation: the low-impedance return path that trips the circuit breaker under fault conditions, protecting both equipment and human life. The stranded bare copper conductor (Class 2 per IEC 60228) ranges from 0.75mm² to 400mm², with a focus on the 10mm², 16mm², and 25mm² sizes most commonly used for main equipotential bonding, supplementary bonding, and circuit protective conductors in both residential and industrial installations.
The PVC insulation compound is specifically formulated for 70°C continuous dry operation with a 160°C/5s short-circuit withstand, and meets the flame retardancy requirements of IEC 60332-1 / GB/T 18380.12. With a 450/750V rating for ≥1.5mm² conductors (H07V-U) and 300/500V for 0.75-1.0mm² (H05V-U), this earth wire is qualified for use in all standard building voltage classes. The minimum bending radius of 15×D (as low as 30mm for 1.0mm²) ensures easy routing through conduit bends and terminal boxes. Operating temperature range is 0°C to +70°C with a minimum installation temperature of 0°C — the same profile as the phase and neutral conductors it accompanies in every building circuit.
The green/yellow colour coding is non-negotiable in international electrical standards: this wire must be used exclusively as a protective earth conductor and must never be repurposed as a phase or neutral conductor. Electricians and panel builders specify green/yellow earth wire alongside phase (brown/black/grey) and neutral (blue) wires to build complete, code-compliant circuits. For main equipotential bonding — the heavy-gauge earth connection linking gas/water pipes to the main earth terminal — 10mm² and 16mm² are the standard sizes per IEC 60364 and BS 7671.

Typical Applications
The green/yellow earth wire is the single most important safety component in any electrical installation. Without it, a fault that energises a metal appliance casing has no path to trip the breaker — leaving the next person who touches it at risk of fatal electric shock:
Main Equipotential Bonding
10-16mm² green/yellow bonding conductor connecting gas, water, and structural metalwork to the main earth terminal per IEC 60364 / BS 7671.
Circuit Protective Conductor
Earth conductor inside every lighting, socket, and appliance circuit. Same size as phase conductor per most wiring regulations.
Earth Electrode Connection
Connection from the main earth terminal to the earth electrode (ground rod, foundation earth, or grid). 16-25mm² stranded typical.
Industrial Panel Earthing
Internal earthing busbar connections in motor control centres, distribution boards, and industrial control panels.
International Code Compliant
Green/yellow is the universal earth colour per IEC 60446. Accepted in all markets: EU, UK, India, Middle East, Asia-Pacific.
Supplementary Bonding
Local bonding between exposed conductive parts in bathrooms, swimming pools, and medical locations where enhanced shock protection is required.
