Description
Product Overview
The RR Kabel Superex-FR 4 sq mm Blue Copper House Wire is purpose-built for circuits that demand higher current-carrying capacity and enhanced safety. With a cross-sectional area of 4 sq mm and pure electrolytic-grade copper conductors, this wire comfortably handles dedicated loads such as 1.5-ton split air conditioners, 3kW geysers, and submersible pump motors — applications where undersized wiring poses a genuine fire and equipment risk. The FR PVC insulation provides flame-retardant protection, ensuring the wire self-extinguishes rather than propagating a flame in the event of an electrical fault.
Supplied in a convenient 90-metre coil, this wire is equally suited to sub-main wiring runs in residential buildings, where a reliable feed from the distribution board to individual circuit breakers is essential. The blue colour coding makes Phase B identification straightforward in three-phase installations and serves as an alternate phase identifier in single-phase systems, reducing the risk of wiring errors on-site. Whether you are wiring a new apartment block, retrofitting a kitchen with dedicated appliance circuits, or connecting a borewell pump, the Superex-FR 4 sq mm Blue gives you the performance margin and safety compliance your project requires.

Why Choose RR Kabel Superex-FR?
- Flame Retardant Safety: The FR PVC insulation is formulated to self-extinguish when the ignition source is removed, significantly reducing the risk of fire spread within walls and conduits — a critical safety requirement in modern Indian construction.
- High-Purity Copper Conductors: RR Kabel uses electrolytic-grade copper with high conductivity, ensuring minimal resistive losses, reduced heat generation, and longer service life compared to substandard alternatives.
- ISI Mark and IS 694:2010 Compliance: Every coil carries the Bureau of Indian Standards ISI mark, confirming third-party tested compliance with IS 694:2010 — the mandatory Indian standard for PVC insulated cables and wires for working voltages up to and including 1100V.
- Consistent Coil Length: The 90-metre coil is factory-measured and sealed, giving contractors and electricians confidence in material planning and reducing on-site wastage.
Colour Code Guide
In Indian electrical wiring practice, blue is used as the Phase B (second phase) conductor colour in three-phase systems, in accordance with guidelines referenced under the National Electrical Code (NEC) India and general industry convention. In single-phase residential wiring, blue is commonly employed as an alternate phase wire where multiple circuits need to be distinguished from the standard red phase conductor. Using correctly colour-coded wires is essential for safe identification during maintenance, fault finding, and future modifications — minimising the risk of accidental contact with live conductors by electricians and technicians.

Frequently Asked Questions
What loads is the RR Kabel Superex-FR 4 sq mm wire suitable for in a home?
The 4 sq mm conductor size is well suited for higher-load household circuits that draw significant current continuously. Typical applications include 1.5-ton split air conditioners, 3kW electric geysers, submersible pump motors, induction cooktops, and sub-main feeds from the main distribution board. Electricians and contractors generally recommend 4 sq mm wiring for any dedicated circuit where the connected load exceeds the capacity of a standard 2.5 sq mm wire.
What does the blue colour on this wire signify in Indian electrical wiring?
In Indian electrical wiring practice, blue designates the Phase B conductor in a three-phase system, making it the second phase colour alongside red (Phase A) and yellow (Phase C). In single-phase installations, blue is frequently used as an alternate phase wire to distinguish separate circuits within the same conduit or distribution board. Following consistent colour coding is a key safety practice recommended under the National Electrical Code (NEC) India, as it allows electricians and technicians to identify live conductors quickly and accurately during installation, maintenance, or fault rectification.
What does FR (Flame Retardant) mean and why is it important for house wiring?
FR stands for Flame Retardant, which means the PVC insulation compound used on this wire is specially formulated to resist the spread of flame. When an ignition source is removed, FR-grade insulation self-extinguishes rather than continuing to burn, which is critical in concealed wiring within walls, conduits, and ceiling voids where a small electrical fault could otherwise cause a serious fire. Using FR-rated wires in residential and commercial buildings is strongly recommended by electrical safety guidelines and is increasingly specified by architects, builders, and municipal authorities across India.
Is this wire compliant with IS 694:2010 and what does that standard cover?
Yes, the RR Kabel Superex-FR range is manufactured to IS 694:2010, the Bureau of Indian Standards specification for PVC insulated cables and flexible cords for working voltages up to and including 1100V. This standard sets mandatory requirements for conductor dimensions, insulation thickness, mechanical properties, electrical performance, and flame retardancy. The ISI mark on every coil confirms that the product has been independently tested and certified by BIS, providing assurance to electricians, contractors, and end-users that the wire meets India’s national safety and quality benchmarks.
