1) Only an accredited person may, after having satisfied himself by means of an inspection and test that an electrical installation complies with the provisions of regulation 4 (1) , or, in the case of an electrical installation existing prior to the coming into force of these regulations, that it is reasonably safe, issue a certificate of compliance in the form of Annexure 1 (The forms are all available in Word for Windows format. See the Forms section for more details). Provided that where any addition or alteration has been effected to an electrical installation for which a certificate of compliance was previously issued, he may issue a certificate of compliance for such an addition or alteration only.
2) If at any time prior to issuing a certificate of compliance any fault or defect is detected in any part of the electrical installation, the accredited person shall refuse to issue such certificate: Provided that if such fault or defect in the opinion of the accredited person constitutes an immediate danger to persons in the case where electricity is already supplied, he shall forthwith take steps to disconnect the supply to the circuit in which the fault or defect was detected.
