Description
Product Overview
The RR Kabel Superex-FR 4 sq mm Black Copper House Wire is purpose-built for circuits that demand consistent performance under sustained electrical load. With a 4 sq mm cross-sectional area, this single-core wire comfortably handles the current requirements of 1.5-ton split air conditioners, geysers rated up to 3kW, and submersible pump installations — applications where undersized wiring is a leading cause of overheating and fire hazard. The FR (Flame Retardant) PVC insulation ensures that in the unlikely event of a fault, the spread of flame is significantly arrested, protecting the building structure and its occupants.
Supplied in a convenient 90-metre coil, this wire is equally suited to sub-main wiring runs in residential buildings, where it connects the main distribution board to secondary circuit boards across floors or wings. The black colour coding identifies it for use as a phase conductor in three-phase installations (typically designated Phase Y or the third phase) or in specific wiring configurations where black is assigned as an alternate phase or neutral identifier. Manufactured from high-conductivity electrolytic copper, the Superex-FR series delivers low resistance, minimal heat generation, and a long service life — making it a trusted choice among professional electricians and electrical contractors across India.

Why Choose RR Kabel Superex-FR?
- FR Safety Compliance: The Flame Retardant PVC insulation meets IS 694:2010 requirements, significantly limiting flame propagation and reducing fire risk in walls, conduits, and trunking.
- High-Purity Electrolytic Copper: RR Kabel uses 99.97{21d06cf633e1d74c16ec73ab43c3358f6d2908066060866fd407f242af8b6688} pure electrolytic copper conductors, ensuring superior electrical conductivity, lower heat generation, and extended wire life compared to inferior alternatives.
- ISI Mark Assurance: Every coil carries the Bureau of Indian Standards ISI mark, confirming compliance with IS 694:2010 — a mandatory requirement for safe residential and commercial electrical installations.
- Consistent Metre Marking: Sequential metre markings printed on the insulation allow electricians to accurately measure cable runs, reducing material wastage on site.
Colour Code Guide
In Indian wiring practice governed by IS 3043 and NBC (National Building Code) guidelines, black is used as an alternate phase conductor colour or specifically to designate the third phase (Phase Y) in three-phase installations. In some older wiring conventions and certain regional practices, black may also be used as a neutral conductor. Electricians and contractors should always verify the colour coding scheme adopted for a specific project and ensure consistent application throughout the installation. When used in a three-phase system, the black wire is typically paired with red (Phase R) and yellow (Phase B) conductors to complete the three-phase supply.

Frequently Asked Questions
What is the 4 sq mm wire suitable for in a home or building?
The 4 sq mm wire is designed for high-load dedicated circuits in residential and light commercial buildings. It is commonly used for air conditioner circuits up to 1.5 ton, geyser connections up to 3kW, submersible pump wiring, and sub-main wiring between distribution boards. Its current-carrying capacity makes it the standard choice for any fixed appliance circuit where a 1.5 sq mm or 2.5 sq mm wire would be insufficient.
What does the black colour indicate in Indian electrical wiring?
In Indian three-phase wiring practice, black is typically used to identify the third phase conductor, often referred to as Phase Y, alongside red (Phase R) and yellow (Phase B). In some older installations and regional wiring conventions, black has also been used to denote a neutral conductor. It is important to follow the specific colour coding scheme defined for each project and to refer to IS 3043 and applicable NBC guidelines for correct colour assignment.
What does FR (Flame Retardant) mean, and why does it matter?
FR stands for Flame Retardant, which means the PVC insulation material is formulated to resist the spread of fire along the cable. In the event of an electrical fault or short circuit, FR insulation will not readily propagate flames, thereby limiting the risk of fire spreading through walls, conduits, and cable trays. This property is particularly critical in residential wiring where cables run inside concealed conduits and early flame arrest can prevent significant structural damage.
How does IS 694:2010 certification affect the quality of this wire?
IS 694:2010 is the Bureau of Indian Standards specification for PVC insulated cables for working voltages up to and including 1100V, and it sets mandatory requirements for conductor resistance, insulation thickness, voltage withstand, and flame retardance. A wire bearing the ISI mark against IS 694:2010 has been independently tested and certified to meet these minimum safety benchmarks. Choosing IS 694:2010 certified wire like the RR Kabel Superex-FR ensures the installation complies with Indian electrical safety regulations and is accepted by licenced electrical inspectors.
