What must be visibly displayed to legally perform electrical work?

To legally perform electrical work, one must visibly display a certificate of competency. This certificate serves as proof that the individual has undergone the necessary training and has met the requirements set forth by regulatory bodies. It signifies the holder's proficiency and qualifications in the field of electrical work, ensuring that they are knowledgeable about safety codes, standards, and practices required in the industry.

This requirement is crucial as it helps maintain safety and quality in electrical installations and repairs, protecting both the professional and the public. The visibility of this certificate during work ensures compliance with local laws and regulations, reinforcing the credibility of the tradesperson.

While having a license is also essential for many electrical professions, the specific question regarding what must be visibly displayed points to the certificate of competency as the correct answer. Insurance proof and permits, while important for other aspects of electrical work, do not fulfill the requirement of visible display in the same context as the certificate of competency does.
