Description
Life Cables 4 mm² Flexible DC Solar Premium Copper Cable
The Life Cables 4 mm² single core flexible DC solar cable is built for Pakistan’s rooftop and ground-mount solar installations, constructed with a premium 99.9% oxygen-free copper (OFC) conductor for reliable outdoor performance and low conductor resistance across long PV wiring runs.
Rated at 250/450 V and 32 Amperes, and constructed to BSS-6004 equivalent, BSS-2004 Pakistan standards, it is supplied on 90-metre reels in Red, Black, Yellow, and Blue for circuit identification.
⚠ Electrical Safety Notice
- All electrical installations must be carried out by a licensed / qualified electrician in accordance with BSS-2004 Pakistan and IEC 60364 wiring regulations.
- Verify the correct cable size for your circuit load. The 32 A rating is for a single cable in open air; derating is required when cables are bunched, enclosed in conduit, or installed at higher ambient temperatures.
- Use proper cable glands, connectors (e.g. MC4 for PV strings), and terminations to prevent insulation damage and maintain outdoor durability.
- Colour coding must follow your system installer’s convention and be documented, per IEC 60446 practice.
- Life Cables accepts no liability for installations not completed by a qualified professional in line with applicable codes.

Frequently Asked Questions
What is 4 mm² DC solar cable used for?
It’s used to wire photovoltaic systems — connecting solar panels in a string, linking panels to a charge controller, and running DC power between controllers, batteries, and inverters — where the cable is exposed to outdoor heat, UV, and weather.
What is the current rating of Life Cables’ 4 mm² solar cable?
32 A as published. Actual current-carrying capacity depends on installation method (open air, conduit, tray), ambient temperature, and bundling — consult a qualified solar installer for your specific string design.
What is the voltage rating?
250/450 V, suitable for standard residential and commercial DC solar circuits. Confirm compatibility with your system’s actual string and battery bank voltage before installation.
Is this cable suitable for outdoor and direct sun exposure?
Its PVC insulation is rated -20°C to +70°C, which covers outdoor solar wiring. [CONFIRM — insert UV/ozone-resistance rating if this insulation compound differs from standard PVC, to match durability claims used on other solar-cable pages].
What is the DC resistance of this cable?
4.61 Ω/km at 20°C as published. Lower resistance means less voltage drop and less heat generation across long array-to-controller or controller-to-battery runs.
Can I get this cable with a PSQCA test report reference?
[QCC/4(362)/18-19]. Contact Life Cables directly via WhatsApp for the latest available compliance documentation.
What colours are available and how many metres per reel?
Red, Black, Yellow, and Blue. Each reel is 90 metres and weighs approximately 5.8 kg. For bulk orders or custom cut lengths, call 0300-0757533.
