Description
Product Overview
The RR Kabel Superex-FR 1 sq mm Black Copper House Wire is engineered for light-duty electrical circuits where safety, durability, and compliance are non-negotiable. With a 1100V voltage rating and IS 694:2010 certification, this single-core wire is wrapped in Flame Retardant (FR) PVC insulation that resists the spread of fire — a critical feature in concealed wiring applications within walls, conduits, and trunking. The 90 metre coil length is practical for medium-scale residential projects, reducing wastage while ensuring enough run for multi-room lighting layouts.
The black colour coding makes this wire immediately identifiable on site, commonly used as the third phase (Phase Y) conductor in three-phase installations or as an alternate phase wire in single-phase systems depending on site convention. For LED lighting circuits, doorbell connections, signal wiring, and indicator lamp circuits, the 1 sq mm conductor cross-section is the correct choice — providing adequate current-carrying capacity for low-load applications without over-sizing, which keeps conduit fill manageable and installation neat. Shansen Enterprises stocks this wire as an authorised RR Kabel dealer, ensuring every coil is genuine, ISI-marked, and traceable.

Applications
- LED Lighting Circuits: Ideal for wiring LED panel lights, strip lights, and downlights in bedrooms, corridors, and commercial spaces where low current draw makes 1 sq mm the correct conductor size.
- Doorbell Wiring: The standard wire gauge for doorbell circuits in residential apartments, independent homes, and gated communities — provides clean, low-resistance connections to doorbell transformers and buzzers.
- Indicator Lamp Connections: Used in distribution boards and control panels to wire indicator lamps and pilot lights that signal circuit status to operators and residents.
- Signal Wiring: Suitable for low-voltage signal runs in home automation systems, security alarm circuits, and intercom installations where current loads are minimal.
- Low-Load Electronic Circuits: Appropriate for wiring small electronic loads such as Wi-Fi routers, set-top boxes, and smart home control modules when run in dedicated conduit.
- Three-Phase Installations (Phase Y): Used as the third phase (Phase Y) conductor in three-phase wiring layouts in accordance with site colour coding practices, making circuit identification straightforward during maintenance.
- Conduit and Surface Trunking Runs: Its slim profile and flexible conductor make it easy to pull through PVC conduit and surface trunking in false ceiling spaces, under-floor channels, and wall chases.
- Light Commercial Fit-Outs: Shops, offices, and showrooms requiring dedicated low-load circuit drops for display lighting and signage benefit from this wire’s reliable FR protection in concealed installations.
Why Choose RR Kabel Superex-FR?
- Flame Retardant FR PVC Insulation: The Superex-FR series uses FR-grade PVC that self-extinguishes when the ignition source is removed, limiting fire propagation through walls and conduits — a critical safety attribute for concealed wiring in homes and commercial buildings.
- High-Purity Electrolytic Copper Conductor: RR Kabel uses electrolytic grade copper with high conductivity, ensuring minimal resistive losses, lower heat generation, and a longer service life compared to wires using lower purity conductor material.
- ISI Mark and IS 694:2010 Compliance: Every coil carries the ISI mark and is manufactured to the Bureau of Indian Standards specification IS 694:2010, giving electricians, contractors, and inspectors confidence in the wire’s performance and regulatory compliance.
- Consistent Coil Length and Quality Control: RR Kabel’s manufacturing process ensures accurate coil lengths and uniform insulation thickness, reducing site disputes and ensuring the stated 90 metres is delivered on every coil without short measure.
Colour Code Guide
In Indian electrical wiring practice, the black colour for single-core wires is associated with the third phase conductor, designated Phase Y (or Phase C) in three-phase AC systems — a convention widely followed across industrial, commercial, and large residential installations in India. In some older or legacy wiring conventions, black has also been used to denote neutral conductors, so it is important that site supervisors and electricians confirm the colour coding convention in use on any given project. When used as Phase Y in a three-phase installation, the black wire should be clearly identified at both termination ends, and all circuit documentation should reflect the colour assignment in compliance with IS 3043 earthing and NEC India guidelines. Using the correct colour-coded wire from the outset simplifies future maintenance, fault finding, and circuit additions without the risk of phase confusion.

Frequently Asked Questions
What is 1 sq mm house wire used for and is it sufficient for home lighting circuits?
A 1 sq mm copper wire is designed for light-duty electrical circuits including LED lighting, doorbell wiring, indicator lamp connections, signal wiring, and low-load electronic circuits in residential and commercial buildings. It carries a safe current of approximately 9 to 11 amperes under standard installation conditions, making it perfectly adequate for lighting circuits where individual loads are low. For circuits feeding power sockets, air conditioners, geysers, or other high-load appliances, a larger conductor size such as 2.5 sq mm or 4 sq mm would be required.
What does the black colour on this house wire signify in Indian electrical wiring?
In Indian three-phase electrical installations, black is conventionally used to identify the third phase conductor, referred to as Phase Y or Phase C, helping electricians and maintenance personnel quickly distinguish between phases during installation and fault-finding. In some older single-phase wiring systems and legacy installations, black has historically also been used for the neutral conductor, so it is essential to confirm the colour coding convention adopted on a specific site before termination. Regardless of the convention in use, the black conductor should be clearly marked at all termination points and reflected accurately in circuit documentation as recommended under IS 3043 and NEC India guidelines.
What does FR (Flame Retardant) mean and why is it important for concealed home wiring?
FR stands for Flame Retardant, a property of the PVC insulation used in the Superex-FR series that causes the material to self-extinguish once the external ignition source is removed, thereby preventing the fire from spreading along the wire’s length through walls, conduits, or ceiling voids. This is a critical safety feature in concealed wiring applications — such as wires buried in wall plaster or run inside PVC conduit — where a standard PVC wire that supports combustion could allow a small electrical fault to develop into a significant structural fire. IS 694:2010 specifies flame retardancy testing requirements for house wiring cables, and RR Kabel Superex-FR is manufactured to meet and exceed these requirements.
Is this wire compliant with IS 694:2010 and what does that standard cover?
Yes, the RR Kabel Superex-FR 1 sq mm Black House Wire is manufactured 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 standard covers critical parameters including conductor resistance, insulation thickness, voltage withstand, flame retardancy, ageing characteristics of the insulation, and dimensional tolerances — ensuring the wire performs safely over its intended service life. The ISI mark on every coil confirms that the product has been tested and certified by BIS, providing assurance to electricians, contractors, electrical inspectors, and building occupants alike.
