CoC - Certificate of Compliance, why do you need it?
Once your solar PV or backup system has been installed, it’s important to ensure that a Certificate of Compliance (CoC) is issued. What is it and why do you need it?
Basically, this document checks that the electrician who performed the installation has complied with the rules and regulations that are in place to assure a safe installation.
As the property owner, you are responsible for the safety of the electrical installation on your property in terms of the OHS Act. According to the Occupational Health and Safety Act, Act 85 of 1993 (OHS Act), the owners of a premise where electricity is consumed need to be in possession of a valid Certificate of Compliance.
Without a valid electrical CoC, you will find it difficult to prove that you have taken reasonable precautions should anything go wrong. Insurance companies might not pay out for damages; and if someone is injured or dies as a result of the installation, you could be held liable as the property owner.
Staff qualifications are important. Before installation, ask for proof of registration (also called a wireman’s licence), and check that it is up-to-date. This is a registration with the Department of Labour. A registration means that the electrician is proficient in the national wiring codes SANS 10142-1:1200, and that he or she can install your PV system safely. It also implies that the electrician is permitted to issue a CoC for the installation, which will confirm that the installation has been performed in compliance with the national wiring codes. A registered person is described more comprehensively under the Electrical Installation Regulations (clauses 9 and 11) of the OHS Act.
