(12) No electric water heater or clothes dryer will be served with smaller wire than #10 AWG copper wire.
(a) No electric hot water heater shall be serviced with electricity until the following is installed: an approved pressure relief valve on the cold water line, or an approved temperature relief valve on the hot water line, or an approved combination pressure and temperature relief valve on the hot water line, with the temperature-sensing element in the top of the tank.
(b) All electric water heaters and clothes dryers shall be properly grounded.
(13) All wiring for light and power shall be installed so as to make all raceways, outlet boxes, and equipment grounded, in accordance with the National Electrical Code.
(14) Recessed fixtures shall not be used as junction boxes.
(15) All service equipment, distribution and control switches shall be readily accessible as defined in the National Electrical Code.
(16) All sump pumps shall be grounded in an approved manner.
(17) The grounding conductor must be connected to the city water piping system, if one is available.
(a) If a city water system is not available, an approved one-half inch in diameter by ten feet in length copper-weld ground rod shall be used for grounding purposes.
(b) If there is a domestic water supply system with any metallic water piping on the premises, this piping shall be grounded to the common neutral ground of the customer service entrance equipment with not less than #6 copper wire. Any rubber or plastic hose connections in the metallic piping system shall be electrically bonded.
(18) Ground clamps on water piping of copper, brass or lead shall be of copper, and those for use on galvanized or iron pipe should be of galvanized iron and so designed that they will avoid mechanical injury to the pipe.
(19) Where the necessity for the temporary use of electric current in any installation is shown to exist, or the temporary use of electrical current is needed during the construction or altering of any building, the Inspector may grant permission for such temporary wiring or apparatus or fixture for a period not exceeding 120 days; however, extension may be granted by the Inspector.
(E) Whenever any of the aforesaid sets of rules, regulations and standards so incorporated herein by reference thereto in the foregoing divisions (C) and (D) above may be hereinafter amended or supplemented and whenever such changes in all or any thereof are adopted by any later ordinance and two copies of any such amended or supplemented rules, regulations and standards or lists are filed with the County Auditor and kept by him or her as aforesaid, any or all of such changed rules, regulations and standards or lists shall thereupon also become a part of this code.
(F) After the effective date of this section, no person, persons or corporations shall install any electrical wiring or electrical installation or make any repairs or either of the same except in accordance with the aforesaid code.
(G) No person, persons or corporation shall use any electrical device installed in violation of this section; however, all electric utilities shall be exempt from the terms of this section and their operation shall be controlled and in conformity with the existing National Electrical Code as the same effects their operations in providing service to their customers.
