Published: 28 October 2026
On 24/09/2026, a landmark judgment was passed in Ogun State. Samson Okonkwo was convicted for selling counterfeit Coleman cables, marking the first known jail term for cable adulteration in Nigeria Source: Punch. The prosecution tendered 317 coils of fake cables as evidence Source: The Nation.
This is not just a legal story. It is a stark warning for every Nigerian homeowner and business owner.
Why should you care? Counterfeit cables are not just poor quality — they are deadly. They can be 30-40% shorter than genuine products, creating serious fire and electrocution risks Source: BusinessDay.
This guide is your definitive resource. We will cover why Coleman cables are the gold standard, the real dangers of fakes, 7 proven methods to spot counterfeits, the full product range, and a step-by-step system to protect your home or business.
Coleman cables are Nigeria’s most trusted electrical wiring brand, but fakes are everywhere. Here is how to tell the difference and stay safe.
Why Coleman Cables Are the Gold Standard in Nigeria
Coleman Technical Industries Limited is Nigeria’s largest cable manufacturer Source: BusinessDay. Their reputation is built on consistency and compliance with Nigerian Industrial Standards (NIS), verified by SON’s dedicated technical committee for Cables and Conductors (SON/TC 088) Source: SON.
Professional electricians prefer Coleman for good reasons:
- Consistent copper quality — Genuine Coleman cables use high-conductivity copper that meets specified gauge sizes.
- Accurate gauge sizes — A 2.5mm² cable is truly 2.5mm², not thinner.
- Durable insulation — The PVC insulation is formulated to resist heat, cracking, and degradation.
- Reliable current-carrying capacity — You can trust the rated capacity without derating for safety.
However, the counterfeit problem is severe. Coleman’s Managing Director, George Onafowokan, has publicly criticised the Standards Organisation of Nigeria (SON) for weak enforcement and called for stiffer penalties, including jail terms, for counterfeiters Source: Guardian.
SON does have a role in quality assurance. It operates an ISO/IEC 17025:2017 accredited laboratory at Ogba, Lagos, that tests PVC and armoured cables Source: SON. Back in June 2024, SON confiscated over ₦30 million worth of SON confiscated over ₦30 million worth of fake cables in a single sting operation in June 2024 [Source: SON]. This represents just a fraction of the illicit trade flowing through Nigerian markets. The black market for substandard electrical materials is estimated to cost the Nigerian economy billions of Naira annually in property damage, lost productivity, and preventable deaths.
The Real Dangers of Fake Coleman Cables
Why is this such a serious issue? Counterfeit cables are not just “low quality”—they are engineered to fail. Here is what is at stake for every Nigerian homeowner and business owner:
Fire Hazard: A genuine 2.5mm² Coleman cable is designed to safely carry up to 20–25 amps. A counterfeit “2.5mm²” cable might have a conductor that is only 1.5mm² or 2.0mm². When you connect a standard 15-amp air conditioner or a 20-amp deep freezer, the undersized wire overheats. The insulation melts, arcs, and ignites surrounding materials. This is the leading cause of electrical fires in Nigerian homes and businesses.
Electrocution Risk: The PVC insulation on fake cables is often made from recycled or low-grade materials. It becomes brittle in the sun, cracks easily, and fails to contain the electrical current. A simple touch of a cracked cable can result in a fatal shock. In a country where earthing is often already substandard, this is an unacceptable risk.
Voided Insurance: This is the silent financial killer. Nigerian insurance companies are increasingly employing forensic electricians to investigate fire claims. If they find substandard or counterfeit wiring, they will deny your claim. You are left with a burnt shell of a building and zero compensation. Your premiums were wasted.
Equipment Damage: Voltage fluctuations are common in Nigeria. Genuine cables help stabilize the system. Fake cables cause voltage drops, which damage sensitive electronics like computers, inverters, and manufacturing equipment. The cost of replacing burnt-out equipment often far exceeds the money “saved” on cheap cables.
7 Proven Methods to Spot Fake Coleman Cables
Let’s get practical. Here is how you can protect yourself, whether you are buying a single coil for a home project or equipping an entire office building.
1. The Weight and Feel Test
This is the easiest test. Pick up a genuine Coleman coil and a suspect one. The genuine article is noticeably heavier. Copper is dense. Counterfeiters often use less copper or mix it with cheaper metals like aluminum or steel. A 50-meter coil of 2.5mm² genuine cable should feel solid and substantial. If it feels light or flimsy, be suspicious.
2. The Sheath Printing Test
Look closely at the text printed on the black or white PVC sheath. Genuine Coleman cables have clear, deeply embossed or sharply printed text. It will state “Coleman Technical Industries Ltd”, the cable size (e.g., 2.5mm²), the voltage rating (e.g., 600V or 100V), and the NIS standard it complies with. Fake cables often have blurry, smudged, or easily scratched-off printing. The font might be slightly different, or the spacing might be off. Run your fingernail over the print. If it smears, it is fake.
3. The Conductor Test (The Micrometer Check)
This is the definitive test. Strip a small section of the insulation. Using a digital caliper or micrometer, measure the diameter of the copper conductor.
- For a solid 2.5mm² conductor, the diameter should be approximately 1.8mm.
- For a stranded 2.5mm² conductor (e.g., 7 strands), each strand should be about 0.67mm.
If the measurement is significantly less, you have a fake. A 1.5mm² conductor masquerading as 2.5mm² is a recipe for disaster.
4. The Copper Color and Flexibility Test
Genuine copper has a distinct bright, slightly orange-red hue. It is also very ductile and flexible. Counterfeit copper is often brittle. If you bend the wire back and forth, genuine copper will bend many times before breaking. Fake copper might snap after just a few bends. Also, look for a dull, greyish, or pinkish tint—this indicates impurities or copper-clad aluminum (CCA), which is a major fire risk.
5. The Packaging and Hologram Test
Coleman has invested in sophisticated packaging. Look for holographic stickers, tamper-evident seals, and unique batch numbers. The packaging should look professional. If the box is faded, the glue is old, or the batch number is handwritten or missing, be suspicious. You can often verify the batch number on the Coleman website or by calling their customer service line.
6. The Price Test
In Nigeria, if a deal looks too good to be true, it is. Counterfeiters thrive on the “I know a guy” economy. A vendor selling “Coleman” cables at 30–50% below the market price is not offering a bargain; they are selling a death trap. Always be suspicious of significant discounts, especially from street vendors or unmarked shops. Know the current market price per meter for each gauge.
7. The Burn Test (For the Brave)
Take a small offcut of the insulation. Genuine Coleman PVC insulation is flame retardant. It will burn if held in a flame, but it will self-extinguish when the flame is removed. It also has a specific, acrid smell. Fake insulation often burns vigorously, drips like plastic, and smells like burning garbage. Warning: Perform this test in a well-ventilated area and keep a fire extinguisher handy.
The Full Coleman Product Range
Coleman manufactures a wide range of cables for different applications. The most counterfeited are the common household and commercial types:
- Flat TPS (Thermoplastic Sheathed) Cables: Used for general house wiring (sockets, lights, ACs). Sizes 1.5mm², 2.5mm², 4.0mm², 6.0mm², etc. This is the most counterfeited category.
- Single Core Cables: Used in switchboards and control panels.
- Armoured Cables (SWA/STA): Used for underground or outdoor connections, and for powering heavy machinery. Fakes here are extremely dangerous as they are often used for high-current applications.
- Welding Cables: Flexible cables for industrial use.
- Automotive Cables: For vehicles and generators.
When buying any of these, apply the 7 tests above. The Flat TPS cables are the most common target for counterfeiters because they are the most widely used.
Step-by-Step System to Protect Your Home/Business
Knowing the tests is one thing. Building a system to protect yourself is another. Here is a practical workflow.
Step 1: Plan Your Purchase
Don’t wait until the electrician is on site and needs cable immediately. Plan ahead. Identify the exact lengths and sizes you need. Get a quote from an authorized Coleman distributor.
Step 2: Buy from Authorized Sources
This is the single most important step. Buy directly from Coleman Technical Industries Ltd, or from their list of authorized distributors. Major hardware chains like BETA, Leks, and Cevian are generally safe. Avoid buying from roadside stalls, unmarked warehouses, or “market men” who come to your site.
Step 3: Inspect Before Installation
Do not let the electrician start cutting and pulling cable before you have inspected it. Open the coil, check the printing, weigh it, and measure the conductor. If you are not confident, ask the electrician to do the tests in front of you.
Step 4: Demand a Receipt
A proper receipt or invoice is your proof of purchase. It should have the vendor’s name, address, date, and a description of the goods. This is crucial for warranty claims and for reporting counterfeits.
Step 5: Hire a Qualified Electrician
A registered electrician with the Nigerian Society of Electrical Engineers (NSEE) or the Nigerian Society of Engineering Professionals (NSEP) will not risk their license by installing fake cables. They know the standards and can verify the materials.
Step 6: Report Suspected Fakes
If you find fakes, do not just accept the loss. Report it. Contact:
- Standards Organisation of Nigeria (SON): They have the mandate to raid and seize fake goods.
- Federal Competition and Consumer Protection Commission (FCCPC): They can prosecute sellers for consumer fraud.
- Coleman Technical Industries Ltd: They have a vested interest in stopping counterfeits and will often take action.
- The Police: The Ogun State case proves that criminal charges can stick. Make a formal complaint at the nearest police station.
Legal & Financial Implications
The financial consequences of using fake cables extend far beyond the initial cost of the wire.
Insurance Voiding: As mentioned, this is the biggest risk. Most Nigerian home and business insurance policies have a clause requiring the property to be maintained in a safe condition. Using substandard or counterfeit electrical materials is a clear breach of this clause. If a fire is traced to a fake cable, the insurer will almost certainly deny the claim. You lose your property and your premium.
Liability for Business Owners: Under the Nigerian Occupational Safety and Health (OSH) framework, employers have a duty to provide a safe working environment. If an employee is electrocuted or a fire injures a customer due to fake wiring, the business owner can be held criminally and civilly liable. This can mean fines, jail time, or massive compensation payouts.
The Ogun State Precedent: The conviction of Samson Okonkwo is a game changer. It shows that the judiciary is willing to impose jail terms, not just fines. This creates a powerful deterrent. It also empowers consumers and regulators. If you are a victim, you can point to this case and demand action from the authorities.
Frequently Asked Questions (FAQ)
Q: I have already installed cables. How can I check them without tearing down my walls? A: You can check the exposed ends at your distribution board, sockets, and switches. Look at the printing on the sheath. If it is blurry or missing, that is a red flag. You can also measure the conductor at the socket terminals. If you are unsure, hire a qualified electrician for a full wiring audit.
Q: Are all cheap cables fake? A: Not necessarily, but price is the strongest indicator. A genuine Coleman cable has a specific cost based on the price of copper and manufacturing standards. If a vendor is selling “Coleman” significantly below this price, they are almost certainly selling fakes. Stick to the authorized price list.
Q: What should I do if my electrician brings fake cables to the job? A: Stop the work immediately. Refuse to pay for the materials. Ask the electrician to provide a genuine replacement. If they refuse, report them to the NSEP or NSEE and find a new electrician. Do not compromise on safety.
Q: Can I get a refund if I bought fake cables? A: Yes, under the FCCPC guidelines, you are entitled to a refund for counterfeit goods. However, it can be a difficult process. Your best bet is to report the seller to the FCCPC and SON immediately. The more people who report, the faster the authorities will act.
Q: Does Coleman have a verification system? A: Yes. Coleman has introduced various anti-counterfeiting features over the years, including holograms and batch number verification. Check the official Coleman website or contact their customer service for the latest verification methods.
