For which of the following reasons can an electrical certificate be revoked?

The reason a certificate can be revoked is primarily related to the integrity of the certification process. When a certificate is obtained through error or fraud, it undermines the trust and safety that certifications are meant to represent in the electrical profession. This can include instances where false information is provided during the application process or when an individual does not meet the necessary qualifications but deceitfully claims otherwise to obtain the certification. Revocation in such cases is essential to maintain high standards in the field and ensure that all certified individuals have met the necessary criteria for safety and competence.

Passing only the written exam does not typically lead to revocation, as certification often requires passing both practical and written components or meeting other specific qualifications as determined by relevant authorities. Similarly, being employed part-time does not affect the validity of a certification since employment status does not inherently question the qualifications or the legitimacy of the certificate. Thus, the focus remains on honesty and accuracy in the certification application process, making the correct reason for revocation one involving error or fraud.
