Any person, electrical business or independent contractor desiring to engage in electrical work within the city shall be required to pass an examination before the Bartholomew County board of electrician examiners concerning their ability, experience, training and fitness to engage in such line of work. Licenses shall be issued without examination to applicants who on October 3, 1960, shall have been actively engaged for at least three years immediately preceding such data in the actual pursuit of the electrical trade, which facts shall be supported by the affidavit of such applicant reciting the place or places and the approximate date or dates when and where such applicant has pursued such occupation during such three-year period. A current electrician's license issued the applicant by any city in the state shall be prima facie evidence of the qualifications of such applicant to engage in the electrical business. If the person applying for a license is not qualified for a license, he shall employ a licensed electrician at all times to supervise any work done under such license. Such electrician shall be responsible to the city and to the owner or occupant of the property jointly with the employer for compliance with all of the provisions of this chapter. (Prior code § 6-16)
