Okla. Stat. tit. 19, § 19-864.11: Manner of installation

All electrical wiring, materials, equipment and the methods of

installation thereof, in every county or metropolitan area subject

to the provisions of this act, shall be installed, furnished and

used in such manner as to protect the safety of all persons and

property affected thereby. Compliance with the electrical code of

any city having a population of one hundred eighty thousand

(180,000), or more, according to the last Federal Decennial Census

or any future Federal Decennial Census, which city is located in the

county of inspection, shall be deemed to be prima facie evidence of

compliance with this act.

If the electrical code of any such city, as defined in this

section, or any electrical code which may be adopted by the board of

county commissioners by virtue of the authority hereinafter granted,

contains no specific standards as to the manner of electrical

wiring, materials, equipment and the methods of installation

thereof, compliance with the statutes of this state pertaining to

the installation of electrical materials and equipment and

conformity with the regulations set forth in then current National

Electrical Code which is the standard of the National Board of Fire

Underwriters for electrical wiring and apparatus, as recommended by

the National Fire Protection Association and approved by the

American Standards Association, shall be prima facie evidence of

conformity with approved standards of safety to persons and property

and of compliance with this act.

In the event that a board of county commissioners of any county

or the governing body of any city affected by this act fails to

enter into an agreement authorized under this act with a city or

county, as the case may be, or if such an agreement is terminated,

the governing body of any city or the board of county commissioners

of such county is hereby granted the authority to adopt an

electrical code for the city or county, as the case may be. Such

code shall not be adopted by the board of county commissioners until

after it has held a public hearing at which all interested persons

have been permitted to appear to express their views as to what

provisions the code should contain. Public notice of such hearing

must be given by the board of county commissioners by publication in

its proceedings at least thirty (30) days prior to the date of said

hearing. From and after the effective date of any county electrical

code adopted by the board of county commissioners under the

authority created herein, all electrical installations within the

unincorporated area of the county must be made to conform therewith.

Such code shall afford safety to persons and property from hazardous

electrical installations, but shall not unduly restrict owners in

the improvement of their property.
