Electrical Certificate of Compliance Elarduspark work starts by defining the fixed installation and why the certificate is needed. A registered person inspects the applicable circuits, protection, earthing and accessible fixed equipment, then records the relevant test results. The owner must address defects, and the registered person must retest them before the certificate decision. Call 911 Electricians Pretoria on 076 895 5655 to discuss the property, existing records and known alterations.
