Product Overview

This premium Meter Tail Pack is purpose-engineered to provide a safe, reliable and compliant electrical connection between consumer units and electricity meters — a critical link in residential, commercial and light-industrial electrical installations across South Africa. Assembled to exacting British and international standards, this ready-to-use pack eliminates guesswork, ensures correct conductor sizing and colour identification, and speeds up on-site installation for electricians, contractors and electrical specification professionals.

Ideal for new installations, meter upgrades, rewiring projects or compliant replacements, this pack combines high-grade stranded copper conductors with robust insulation and sheathing, delivering consistent performance even under demanding operating conditions. Whether you are designing a residential housing development, maintaining a commercial property or sourcing certified components for large-scale projects, this meter tail assembly offers the assurance of full traceability, third-party approval and long-term reliability.

What's Included in the Pack

Each complete assembly contains three factory-specified cables, matched and sized for standard single-phase and common three-phase meter-to-consumer unit connections:

All cables are supplied cut-to-length and ready for installation, with consistent conductor characteristics across the assembly for balanced electrical performance.

Quality Assurance & Certification

• ✅ BASEC Approved — independently tested and certified to meet British and European safety and performance standards

• ✅ ISO 9001 Certified Manufacturing — consistent quality management from raw copper to finished cable

• ✅ Fully compliant with relevant BS EN standards for conductor construction, insulation performance and marking

• Traceable batch coding and permanent identification marking on every cable

• Manufactured and tested to withstand the rigours of both indoor and protected outdoor installation environments — common across South Africa’s varied climatic regions from Western Cape to Gauteng and KwaZulu-Natal.

Typical Applications & Use Cases

This Meter Tail Pack is designed specifically for direct connection between the electricity meter and the consumer unit (distribution board) — the point where utility supply enters the installation and splits into individual circuits. Common applications include:

• Residential housing — free-standing homes, townhouse complexes and apartment blocks

• Commercial premises — offices, retail spaces and business parks

• Light-industrial units and workshops

• Social housing and public infrastructure projects

• Meter replacement and upgrade programmes

• Compliance retrofits where older tails need upgrading to meet modern safety standards

In South Africa, where electrical installations must comply with the SANS 10142 Wiring Code, correctly sized and colour-identified meter tails are a key requirement for a valid Certificate of Compliance (CoC). Using pre-assembled, certified packs removes sizing errors and colour confusion — helping installers and property owners meet regulatory requirements first time, every time.

Why Choose This Meter Tail Pack?

✔ Correct Sizing & Balanced Performance

All three cables are matched for equal current capacity (114 A) and conductor resistance, ensuring balanced load handling and consistent fault-current performance across Live, Neutral and Earth — critical for protection device operation and system safety.

✔ Double Insulation for Added Protection

The 6181Y Live and Neutral tails feature double insulation — a vital safety advantage over single-core single-insulated cables, reducing risk of short-circuit or earth fault should the cable be accidentally damaged during installation or service.

✔ Clear Colour Identification

• Grey outer on Live/ Neutral tails with distinct internal core colours for quick phase identification

• Green/Yellow on Earth conductor — internationally recognised and compliant with South African wiring practice

✔ Durable in African Conditions

Formulated to perform reliably from winter cold on the Highveld to coastal heat and humidity, the insulation and sheathing remain flexible and resistant to ageing across the full -15 °C to +70 °C operating range.

✔ Certified & Specifier-Friendly

BASEC approval and ISO 9001 certification mean this assembly is widely accepted by electrical engineers, municipal supply authorities and inspection bodies across South Africa and the SADC region. You can specify it with confidence in tender documents and project specifications.

✔ Ready-to-Install, Time-Saving

Supplied cut to your chosen length — no more cutting and matching three separate cables on site. Order 1 m for close-coupled meter/ board installations, 2 m for standard setups, or 3 m where extra reach is needed.

Installation Notes

• Minimum bending radii must be observed during installation to avoid insulation damage — 8× diameter for 6181Y, 5× diameter for 6491X

• Terminations at meter and consumer unit must be correctly torqued in accordance with manufacturer and local authority requirements

• Suitable for installation in meter boxes, conduit or protected trunking — not intended for direct burial or open unprotected outdoor use without additional mechanical protection

• Always install in accordance with SANS 10142, the current edition of the South African National Standard Wiring Code, and local municipal supply authority requirements
