How to Identify Certified Electrical Cables and Devices
The Egyptian market is full of cables and electrical devices that look identical on the outside — but some are uncertified and may carry a smaller copper cross-section than claimed. This guide teaches you how to distinguish a certified product before buying and before installation.

Quick Answer
Practical guide to identifying certified electrical cables and devices in Egypt — EOS mark location on cables, actual cross-section test, certified brands, and how to spot counterfeit products.
Practical Guide: How to Verify Cable and Device Certification
- EOS mark location on cables — The EOS mark and standard number (e.g. ES 4580) are printed in raised ink on the outer cable jacket approximately every metre. The print should be clear and continuous, including the manufacturer's name, cable cross-section, and rated voltage.
- The CE mark and its status in Egypt — CE is a European mark indicating compliance with European standards. In Egypt, CE is accepted on imported products as a technical reference but does not equal EOS. A product bearing CE alone without EOS may not comply with precise Egyptian ES specifications.
- Actual cross-section test by weight — The most reliable method to verify cable cross-section: cut 1 metre of cable, separate the copper and weigh it. A certified 2.5 mm² copper cable weighs approximately 22–23 grams per metre. Any lower weight indicates a smaller cross-section than claimed.
- Certified cable brands in Egypt — Among the most prominent EOS-certified brands: Elsewedy Cables, Kabelwerk, Supreme Cables. These companies provide compliance certificates with each batch and enable digital certification verification.
- How to spot counterfeit or substandard cables — Warning signs: irregular or faded jacket printing, very light yellow copper colour (may be coated aluminium), jacket cracks easily under pressure, price more than 30% below market without clear justification.
- Certified circuit breakers in Egypt — Brands with ES 2674 certification and wide presence in the Egyptian market: Schneider Electric, Legrand, ABB, Hager. These brands supply genuine breakers with precise, tested trip values in accordance with the standard.
- Red flags of counterfeit products — No standard number on the body, no compliance certificate with the shipment, the original brand logo counterfeited in a different font, the breaker does not trip under overload testing, and price unreasonably below the official distributor.
Frequently Asked Questions
Can price alone be used to judge cable quality?
No. A very low price may indicate a cable with a smaller copper cross-section or poor insulation. But a high price alone doesn't guarantee certification. Always verify the EOS mark and standard number, and buy from an officially authorised distributor.
How do I verify that a Schneider or Legrand breaker I bought is genuine?
Via the code on the device and the company's official website or verification app. Schneider, Legrand, and ABB provide authenticity verification tools on their websites, and some via QR code on the packaging. Always buy from an officially certified distributor.
Are aluminium cables permitted in residential units?
Aluminium cables are permitted for main building supply (from the meter to the distribution panel) in large cross-sections. They are not recommended and not common for internal wiring of apartments and units. The Egyptian code favours copper for internal installations.
Is CE mark sufficient to use a product in Egypt?
CE is accepted as a technical reference but does not equal EOS. CE-only products without EOS may be used but are not considered compliant with official Egyptian specifications. For official projects or those requiring engineering sign-off, EOS certification or an Egyptian ES standard is generally required.
How accurate is the scale test for cables?
The weight test is very accurate. A standard 2.5 mm² copper cable weighs approximately: copper = 22.4 g/m. With insulation approximately 38–42 g/m. If the weight of copper extracted from one metre is below 20 grams, this indicates an actual cross-section smaller than 2.5 mm².
