Description
Product Overview
The RR Kabel Superex-FR 6 sq mm Black Copper House Wire is purpose-built for high-current applications that demand consistent electrical performance and robust safety. This single-core wire features a tinned electrolytic copper conductor of 6 sq mm cross-section, sheathed in Flame Retardant (FR) PVC insulation rated for a maximum voltage of 1100V. Supplied in a convenient 90-metre coil, it is ideal for sub-main and final circuit wiring in both residential complexes and commercial buildings across India.
The black colour of this wire makes it the preferred choice for three-phase installations, where it conventionally designates the Y-phase (third phase) as per Indian wiring practice. It is equally used in larger residential projects for high-draw appliances such as 1.5-ton and 2-ton split air conditioners, heavy-duty geysers rated 3 kW and above, and motor circuits up to 3 HP. The 90-metre coil length reduces wastage on mid-to-large projects, making it the go-to choice for professional electricians and electrical contractors who value both quality and efficiency.

Applications
- Split Air Conditioner Circuits (1.5 Ton & 2 Ton): Handles the continuous high current draw of inverter and non-inverter AC units safely.
- High-Capacity Geyser Connections: Suitable for 3 kW to 4.5 kW storage and instant geysers requiring a dedicated heavy-load circuit.
- Main Wiring Runs from Distribution Board: Used as sub-main cables running from the main DB to secondary distribution boards in homes and offices.
- Three-Phase Installations (Y-Phase): Serves as the third phase (Y-phase) conductor in three-phase commercial and industrial wiring layouts.
- Motor Connections up to 3 HP: Powers single-phase and three-phase motors used in water pumps, grinders, and compressors.
- Commercial Building Sub-Main Cables: Ideal for sub-main distribution runs in retail shops, offices, and small commercial establishments.
- Industrial Lighting and Power Circuits: Supplies power to heavy-duty lighting panels and power outlets in workshops and factories.
- Heavy Appliance Dedicated Circuits: Used for dedicated circuits serving ovens, induction cooktops, and other high-wattage kitchen appliances in modern homes.
Why Choose RR Kabel Superex-FR?
- Flame Retardant FR PVC Insulation: The Superex-FR series is manufactured with FR-grade PVC that self-extinguishes and restricts flame spread, significantly reducing the risk of fire propagation in wall conduits and concealed wiring — a critical safety feature for any occupied building.
- High-Purity Electrolytic Copper Conductor: RR Kabel uses 99.97{21d06cf633e1d74c16ec73ab43c3358f6d2908066060866fd407f242af8b6688} pure electrolytic copper, ensuring low resistivity, minimal heat generation at rated loads, and a longer service life compared to wires using lower-grade conductor material.
- ISI Mark & IS 694:2010 Compliance: Every coil of Superex-FR carries the Bureau of Indian Standards (BIS) ISI mark, confirming that the wire has been independently tested and certified against IS 694:2010 — the governing Indian standard for PVC insulated cables for working voltages up to and including 1100V.
- Precise 90-Metre Coil Length: The coil is machine-measured to deliver a true 90 metres, preventing the shortfalls that often occur with loose or hand-wound coils, helping contractors estimate material requirements accurately and reduce project cost overruns.
Colour Code Guide
In Indian electrical wiring practice, the black wire carries a specific and important convention. As per the National Electrical Code India (NEC India) and widespread industry practice, black is used to denote the Y-phase (third phase) in three-phase, four-wire systems — where the three phases are typically identified as Red (R-phase), Yellow (Y-phase), and Blue (B-phase), with black serving as an alternate for Y-phase in many regional and commercial wiring conventions. In older single-phase residential installations, black was also used as the neutral conductor. For three-phase motor connections, sub-main runs, and commercial installations, the black wire in this coil is correctly deployed as the Y-phase conductor. Always verify colour coding with the site’s wiring scheme and consult a licensed electrician to ensure compliance with local practices and IS 3043 earthing standards.

Frequently Asked Questions
What is the 6 sq mm wire used for in home and commercial wiring?
The 6 sq mm wire is designed for high-current circuits that standard 1.5 sq mm or 2.5 sq mm wires cannot safely handle. Common applications include split air conditioners up to 2 ton, high-capacity geysers of 3 kW and above, sub-main cable runs from distribution boards, and motor connections up to 3 HP in residential and light commercial settings. It is also the standard choice for three-phase sub-main distribution in commercial buildings and small industrial premises.
What does the black colour signify in Indian electrical wiring?
In Indian electrical wiring practice, black is conventionally used to identify the Y-phase (Yellow phase or third phase) conductor in three-phase, four-wire installations, where the phases are colour-coded as Red, Yellow/Black, and Blue. In some older residential wiring schemes, black was also used to denote the neutral conductor in single-phase systems. It is important to always confirm the colour coding in use at your specific installation site and follow the guidance of a qualified electrician to ensure safe and compliant wiring.
What does FR (Flame Retardant) mean and why does it matter?
FR stands for Flame Retardant, which means the PVC insulation used in the RR Kabel Superex-FR series is specially compounded to self-extinguish and limit the spread of flame if the wire is exposed to fire. Unlike standard PVC insulation, FR-grade insulation does not continue to burn once the ignition source is removed, which is critical in concealed wiring within walls, conduits, and false ceilings where a fire could spread unseen. This makes FR-rated wires strongly recommended — and in many project specifications, mandatory — for all permanent building wiring in India.
Is the RR Kabel Superex-FR 6 sq mm wire compliant with IS 694:2010?
Yes, the RR Kabel Superex-FR 6 sq mm Black House Wire is manufactured and tested in full compliance with IS 694:2010, the Bureau of Indian Standards specification for PVC-insulated cables for voltages up to and including 1100V. Each coil carries the ISI mark, which confirms that the product has been independently certified by BIS and meets all requirements for conductor resistance, insulation thickness, voltage withstand, and flame retardancy as specified in the standard. Buying ISI-marked wire is essential to ensure safety, insurance compliance, and regulatory approval in construction projects.
