Description
Product Overview
The RR Kabel Superex-FR 4 sq mm Green Copper House Wire is purpose-built for earthing and grounding applications in modern Indian homes, apartments, and light commercial buildings. Manufactured under the Superex-FR series, this wire carries FR (Flame Retardant) PVC insulation rated at 1100 volts and fully complies with IS 694:2010 — the Bureau of Indian Standards specification for PVC insulated cables for working voltages up to and including 1100V. The green colour coding is internationally and domestically recognised as the dedicated earth conductor colour, making identification straightforward during installation, inspection, and maintenance.
The 4 sq mm conductor cross-section is the recommended size for earthing conductors associated with circuits serving 1.5-ton air conditioners, geysers up to 3kW, submersible pump panels, and kitchen appliance dedicated points. The 90-metre coil length is ideal for wiring a full floor of a residential building or a medium-scale rewiring project without mid-run joints. With electrolytic-grade copper ensuring minimal resistance and maximum conductivity, this wire provides a low-impedance earth path that is critical for the safe and reliable operation of MCBs, ELCBs, and RCCBs during fault conditions.

Why Choose RR Kabel Superex-FR?
- Flame Retardant Safety: FR PVC insulation is formulated to self-extinguish and prevent flame propagation, significantly reducing the risk of fire spread in concealed conduit and surface wiring installations.
- ISI Certified Quality: Every coil carries the ISI mark under IS 694:2010, assuring buyers of consistent conductor dimensions, insulation thickness, and electrical performance verified by BIS-accredited testing.
- High-Purity Copper Conductor: Electrolytic-grade copper ensures superior conductivity, a low earth fault loop impedance, and long-term resistance to oxidation — essential qualities for a safety-critical earth conductor.
- Durable Insulation: The robust FR PVC outer insulation withstands mechanical abrasion during conduit pulling and remains stable across the temperature variations typical in Indian climatic conditions.
Colour Code Guide
Green is universally designated as the earth or protective conductor colour in Indian wiring practice and is mandated by IS 3043 — the Indian Standard Code of Practice for Earthing. In a correctly wired installation, the green wire connects all exposed metal parts — including appliance bodies, switch boxes, metal conduits, and distribution board enclosures — to the main earthing terminal and ultimately to the earth electrode. This low-resistance path allows fault current to flow safely to earth, enabling the upstream MCB or RCCB to trip promptly and protect occupants from electric shock. Using the correct green-coloured wire ensures that maintenance electricians and inspectors can immediately identify the earth conductor, reducing the risk of dangerous miswiring during future repairs or alterations.

Frequently Asked Questions
What is RR Kabel Superex-FR 4 sq mm wire used for in a home?
The 4 sq mm wire is suited for circuits that carry moderate-to-high electrical loads, including dedicated points for 1.5-ton air conditioners, geysers up to 3kW, submersible pump wiring, and kitchen appliances such as ovens and chimneys. It is also used as a sub-main conductor within residential distribution boards where individual branch circuits are fed from a common panel. In the green variant specifically, it serves as the earth continuity conductor for all such circuits, providing a safe fault current return path.
Why is green colour used for earthing wire in Indian electrical installations?
Green is the internationally recognised and IS 3043-mandated colour for protective earth conductors in Indian wiring practice. Using a distinctly coloured green wire for earthing ensures that any electrician or inspector working on the installation at a later date can immediately identify the earth conductor without ambiguity, preventing dangerous miswiring. IS 3043 requires that all exposed metal enclosures, appliance bodies, and structural metalwork be connected to the earth electrode via a continuous green earth conductor.
What does FR (Flame Retardant) mean and why does it matter for house wiring?
FR stands for Flame Retardant, which means the PVC insulation compound is specially formulated to resist ignition and, if it does catch fire, to self-extinguish rather than sustain or spread a flame along the wire. In residential wiring, cables are often routed through concealed conduits within walls and ceilings where a fire that starts in the wiring can go undetected for critical minutes. FR-grade insulation significantly reduces this risk and is the minimum recommended insulation type for all fixed house wiring as per good wiring practice in India.
Is RR Kabel Superex-FR compliant with IS 694:2010 and what does that mean for buyers?
Yes, the RR Kabel Superex-FR series carries the ISI mark and is manufactured in accordance with IS 694:2010, which is the Bureau of Indian Standards specification governing PVC insulated cables for voltages up to 1100V. Compliance with this standard means the wire has been tested and certified for conductor resistance, insulation thickness, voltage withstand, and flame retardancy by a BIS-accredited laboratory. For buyers, this provides assurance that the wire will perform consistently and safely over its service life and will satisfy the requirements of electrical inspectors and insurance assessors.
