Description
Product Overview
The RR Kabel Superex-FR 2.5 sq mm Black Copper House Wire is purpose-built for power circuits that demand consistent performance and enhanced safety. With a 2.5 sq mm cross-sectional conductor area, this wire comfortably handles the current loads associated with 15A socket outlets, making it the standard choice for wiring power points in kitchens, utility rooms, garages, and commercial spaces. Its FR (Flame Retardant) PVC insulation is specially formulated to resist the spread of flame, reducing fire hazards in enclosed walls and conduits where heat build-up can be a concern.
Manufactured under the Superex-FR series by RR Kabel — one of India’s most trusted wire and cable brands — this 90 metre coil is designed for medium to large wiring projects where uninterrupted runs are essential. The black colour coding makes it suitable for use as a phase conductor in three-phase installations (typically denoting the Y-phase or third phase) or in specialised wiring layouts that call for an alternate phase identification colour. Whether you are an independent electrician working on a residential fit-out or a building contractor wiring an entire commercial floor, the RR Kabel Superex-FR 2.5 sq mm Black wire delivers the quality assurance of an ISI-marked product compliant with IS 694:2010.

Why Choose RR Kabel Superex-FR?
- Flame Retardant FR PVC Insulation: The Superex-FR insulation compound is engineered to self-extinguish, preventing flame propagation within wall conduits and trunking — a critical safety requirement in modern construction and mandated by good wiring practice under NEC India guidelines.
- 99.97{21d06cf633e1d74c16ec73ab43c3358f6d2908066060866fd407f242af8b6688} Electrolytic Grade Copper Conductor: Superior copper purity ensures low resistance, minimal heat generation, and maximum current-carrying efficiency, reducing energy loss across long wiring runs.
- ISI Mark and IS 694:2010 Compliance: Every coil carries the Bureau of Indian Standards ISI mark, confirming that the product has been independently tested and certified to meet India’s national standard for PVC insulated cables for working voltages up to and including 1100V.
- Consistent Metre Marking: Sequential metre markings printed on the insulation allow electricians to accurately measure cable runs on site, reducing material wastage and improving project efficiency.
Colour Code Guide
In Indian electrical wiring practice, black is recognised as a phase conductor colour, most commonly assigned to the Y-phase (third phase) in three-phase, four-wire systems used in residential complexes, commercial buildings, and light industrial installations. This follows the conventional colour coding widely practised across India, where R-phase is denoted by red, Y-phase by yellow or black, and B-phase by blue. In some older single-phase wiring conventions, black has also been used as a neutral conductor; however, in new installations, electricians and contractors should follow the current IS 3043 and NEC India recommended colour coding to avoid ambiguity. Always confirm the intended use of the black conductor with the project’s wiring diagram before installation.

Frequently Asked Questions
What is the 2.5 sq mm wire size used for in home and commercial wiring?
The 2.5 sq mm conductor size is the standard gauge specified for 15A power socket circuits in residential and commercial buildings across India. It is suitable for wiring dedicated outlets for water heaters (geysers) up to 2kW, washing machines, air coolers, microwave ovens, and general power sub-circuits in distribution boards. Its current-carrying capacity makes it the go-to choice wherever a heavier load than a standard 5A lighting circuit is expected.
What does the black colour indicate in Indian house wiring?
In Indian three-phase wiring practice, black is conventionally used to identify the Y-phase (third phase) conductor in a three-phase, four-wire system, alongside red for R-phase and blue for B-phase. In some older single-phase installations, black was also used as a neutral conductor, though this convention has largely been replaced in modern wiring. Electricians and contractors should always verify the colour assignment against the project’s wiring diagram and follow IS 3043 and NEC India guidelines to ensure clear and safe conductor identification.
What does FR (Flame Retardant) mean and why is it important?
FR stands for Flame Retardant, which means the PVC insulation compound used on the wire is specially formulated to resist ignition and self-extinguish if a flame source is removed, thereby limiting the spread of fire along the cable run. This is a critical safety property in concealed wiring within walls, conduits, and false ceilings where a localised fault or short circuit could otherwise cause a fire to propagate undetected. Choosing an FR-rated wire like the RR Kabel Superex-FR is strongly recommended for all residential, commercial, and institutional wiring projects as a fire safety best practice.
Is the RR Kabel Superex-FR 2.5 sq mm wire compliant with IS 694:2010?
Yes, the RR Kabel Superex-FR 2.5 sq mm wire is manufactured and tested in full compliance with IS 694:2010, the Bureau of Indian Standards specification for PVC insulated cables for working voltages up to and including 1100V. The product carries the ISI mark, which confirms that it has passed independent third-party testing for conductor resistance, insulation thickness, voltage withstand, and flame retardancy as required by the standard. This certification makes it suitable for use in all regulated electrical installations across India.
