Exhibits must illustrate applications and utilize electrical energy. The exhibit must have been constructed by the exhibitor during the year exhibited and must meet electrical safety standards. All exhibits, except lamps, will be judged on electrical wiring, connections, electrical components, usefulness of exhibit, working condition, complexity and design, appearance, originality, workmanship, and safety. Lamps will be judged as described in each class.

 

A 4-H member can have only one (1) exhibit in each class. Exhibits should be permanently signed and dated on the bottom or in another inconspicuous location. If not marked, judges my mark or punch.
