Does Nigeria have an earthing standards like other countries do?

Hi Nkiruka,

Thank you for your question regarding Nigerian Earthing Standards.  It is our pleasure to help.

The Standards Organization of Nigeria (SON) started to function on 1 January 1970.  SON’s governing body is known as the Nigerian Standards Council. This is the Policy making body for supervising the administration and financial management of the Organization. The Director General of the Organization is the Chief Executive whose responsibilities revolve around the day-to-day administration of the Organization within the broad guidelines approved by the Council.  The mandate of the Organization includes preparation of Standards relating products, measurements, materials, processes and services amongst others and their promotion at National, Regional and International levels; certification of products, assistance in the production of quality goods and services; improvement of measurement accuracies and circulation of information relating to standards.  You can find more information here:


Nigeria is a member of the ISO (International Organization for Standardization) and uses a combination of ISO and IEC standards when regulating the electrical industry.  In particular, Nigera conforms to the IEC 60364 Electrical Installations for Buildings.  IEC 60364 is the International Electrotechnical Commission’s international standard on electrical installations of buildings.  It is known as a harmonization standard, as it attempts to rectify the differences between a number of other standards in use across many different nations.  IEC 60364 Section 54 covers Earthing and Grounding related issues.  Please note that IEC 60364 is not a standalone document such as that found with NFPA 70 the National Electrical Code used in the United States.  IEC 60364 must be used in conjunction with a number of other standards, such as the British Standard BS 7671 “Requirements for Electrical Installations”.

Unfortunately, E&S Grounding does not have any direct knowledge as to the specific standard(s) that are currently in use in Nigeria.  We recommend you contact the Standards Organization of Nigeria (SON) for specific references.

We hope you have found this information useful, please do not hesitate to contact us again in the future should you need have any additional questions.

Best regards,

The Engineering Team at E&S Grounding Solutions
