A Study on the Conductivity and Quality of Household Electrical Wires in Nigeria

Electricity powers essential services like appliances, healthcare, and transportation, but its widespread use also introduces risks, especially with defective wires or improper installations. This study investigates the resistivity of household electrical wires in Nigeria due to increasing fire incidents linked to poor wiring. Ten cable brands were tested for conductor and insulation resistance. Results showed significant variability in quality, with only two brands (20%) meeting acceptable standards for conductor resistance, while the other 80% exceeded safe limits, raising the risk of electrical hazards such as overheating. All brands, however, met the required standards for insulation resistance, indicating adequate outer protection. The findings stress the need for careful assessment of electrical wires, particularly with economic pressures leading to substandard materials in the market. This study aims to raise awareness about electrical safety and guide future regulations and policies to improve household electrical standards in Nigeria.
