Description
Product Overview
The RR Kabel Superex-FR 2.5 sq mm Black Copper House Wire is engineered for reliable performance in power-intensive circuits across residential, commercial, and light industrial installations. Carrying a 1100V rating and manufactured in strict compliance with IS 694:2010, this wire is the preferred choice of professional electricians and licensed electrical contractors across India. The 200-metre coil format is ideal for medium to large wiring projects, reducing the need for frequent joins and ensuring a cleaner, more reliable installation throughout the building.
The black colour of this wire holds specific significance in Indian wiring practice, particularly in three-phase installations and certain legacy wiring configurations. When used in single-phase domestic circuits, it is commonly deployed as an alternate phase conductor, while in three-phase systems it conventionally denotes the Y-phase (third phase). The Superex-FR series features FR PVC insulation that resists flame propagation, helping to contain electrical fires and limit damage in the event of a fault — a critical safety feature for any permanent wiring installation in homes, offices, or commercial buildings.

- ISI Mark and IS 694:2010 Compliance: Every metre of Superex-FR wire is manufactured to meet the Bureau of Indian Standards specification IS 694:2010, providing assurance of quality, safety, and dimensional accuracy.
- Trusted Brand Reliability: RR Kabel is one of India’s leading wire and cable manufacturers with decades of presence in the Indian electrical industry, making Superex-FR a dependable choice for professional and domestic wiring alike.
Colour Code Guide
In Indian electrical wiring practice, the black wire carries specific conventional meanings depending on the type of installation. In three-phase wiring systems, black is widely used to identify the Y-phase (third phase) conductor, alongside red for R-phase and blue or yellow for B-phase, in accordance with common Indian site practice. In single-phase circuits, black is sometimes used as an alternate phase conductor, particularly in older installations or where multiple circuits share a conduit and colour differentiation is required. Electricians and contractors should always verify the colour convention being followed on a specific site and comply with the relevant provisions of the National Electrical Code (NEC) India and IS 3043 for earthing and wiring identification to ensure safe and compliant installations.

Frequently Asked Questions
What is the RR Kabel Superex-FR 2.5 sq mm wire suitable for in home wiring?
The 2.5 sq mm wire is specifically suited for circuits that draw higher currents than standard lighting loads. In residential installations, it is the standard choice for 15A power socket outlets, washing machine connections, water heater (geyser) circuits up to 2kW, and air cooler wiring — anywhere a 15-ampere rated circuit is required as per Indian wiring standards.
What does the black colour signify in Indian electrical wiring?
In Indian three-phase wiring practice, black conventionally identifies the Y-phase (third phase) conductor, used alongside red for R-phase and blue or yellow for B-phase. In certain single-phase or older wiring installations, black may also be used as an alternate phase conductor. It is always advisable to verify the colour convention on site and follow IS 3043 and NEC India guidelines for correct identification.
What does FR (Flame Retardant) mean, and why does it matter for house wiring?
FR stands for Flame Retardant, which means the PVC insulation used on the wire is chemically formulated to resist igniting and to self-extinguish if exposed to a flame source, rather than propagating fire along its length. This is a critical safety feature for wires installed inside walls, conduits, and ceiling voids, where a conventional wire catching fire could rapidly spread to surrounding structures — making FR insulation an important protection for occupants and property.
Is the RR Kabel Superex-FR wire IS 694:2010 certified, and what does that mean?
Yes, the RR Kabel Superex-FR range is manufactured in compliance with IS 694:2010, which is the Bureau of Indian Standards specification governing PVC insulated cables for voltages up to and including 1100V. Compliance with this standard means the wire has been tested for conductor resistance, insulation quality, voltage withstand, and dimensional accuracy, confirming it meets the minimum safety and performance requirements mandated for electrical installations in India.
