Any person aggrieved by any ruling, decision, interpretation or order of the Electrical Inspector shall have the right to appeal to the electrical appeal board by filing a written notice of such appeal with the Clerk within ten (10) days from the date of the Electrical Inspector’s ruling. If such a notice is filed, the appeal board shall set a time and place for hearing and so notify the party that has filed the appeal. The hearing shall be open to the public and subject to the time limitation set out in Section 157.19. The electrical appeal board by majority vote shall affirm, modify or reverse any appealed ruling, decision, interpretation or order of the Electrical Inspector. The electrical appeal board may permit variance from the strict terms and provisions of this chapter, if such variance can be made without increasing the hazards to the health or safety of persons or property, and when the granting thereof will not violate the intent and purpose of this chapter. Mere inconvenience to the appellant is not grounds for the granting of such variance.
