Upon the completion of the wiring of any building for light, heat or power, it shall
be the duty of the person doing same to notify the electrical inspector, who shall
without unnecessary delay inspect such wiring and appliances, and if approved by him,
he shall issue a certificate of satisfactory inspection, which shall contain the date
and an outline of the result of his inspection, but, no such certificate shall be
issued unless such electrical wiring and appliances be in strict conformity with the
rules and regulations prescribed or required by this chapter, nor shall any current
be turned on such installation until such certificate is issued.
