All firms shall have a master electrician who has met the requirements of the Examining Board and has thereby shown himself or herself qualified to engage in the business of a master electrician, as a bona fide officer or member of the firm. Before the firm shall be registered in its firm name, as a master electrician, there shall be filed with the Examining Board a certificate from the Examining Board showing the fitness and competency of the officer or member of the firm to engage in the business of master electrician; provided, that if, after a certificate of registration is issued to the firm, the master electrician as an officer of the firm shall withdraw therefrom and cease to be connected therewith, then the Examining Board shall forthwith revoke the certificate of registration of the firm.
