Jackson Code of Ordinances § 14-115
in effectSec. 14-115. - Electrical.
The provisions which follow shall apply to the electrical equipment and materials used in amusement rides and attractions:
(1) Conformity to National Electrical Code. Electrical conductors and electrical equipment installed and utilized on or around permanent or temporary amusement parks and amusement rides or attractions shall conform to National Electrical Code, NFPA Number 70, 1981 edition, as revised, which is incorporated in this subsection by reference.
(2) Installation. Portable electrical systems required by amusement rides or attractions erected temporarily at carnivals, fairs and amusement parks shall be installed by an electrician qualified by training or experience.
(3) Grounding. A carnival may not operate until all grounding electrode conductors, equipment and safety grounding connections are secured, polarized and tested. The grounding conductors shall conform to the National Electrical Code, NFPA Number 70, 1981 edition, as revised, article 250, "Grounding," paragraphs 250-94, "Alternating Current Systems," and 250-95, "Size of Equipment Grounding Conductors." The path to ground from circuits, equipment and conductor enclosures shall:
a. Be permanent and continuous;
b. Have ample carrying capacity to conduct currents liable to be imposed on it; and
c. Have impedance sufficiently low to limit the potential above ground and to facilitate the operation of the overcurrent devices in the circuit.
(4) Service ground. Equipment or generators operating from a separate supply or supplies which are located closer than eight feet and all service equipment within itself shall be bonded together. The service ground shall be established by connecting the grounding conductor to the service entrance neutral bar in the hot truck or generator and to an approved type service grounding electrode such as ground rods. A sufficient number of ground rods shall be spaced not less than six feet apart and at a secure depth to obtain and maintain 25 ohms or less resistance to ground. A resistance to three ohms or less shall exist when grounding to a water system.
(5) General grounding. Where electrical power is supplied for an amusement ride or attraction erected permanently or temporarily at carnivals, fairs, and amusement parks by a privately operated generating system, the generator and all equipment shall be properly grounded.
(6) Circuit and equipment safety. From the service entrance neutral bar, the circuit grounding and equipment safety grounding conductors shall be continuous and separate throughout the entire system. The portable outlet and terminal boxes shall contain a service ground through grounded receptacles for both circuit and safety. The equipment safety grounding conductors shall be attached to each ride or attraction or concession booth such that a grounding resistance of 25 ohms or less is obtained. Separate steel tracks or steel framework, such as roller coaster tracks or big slides, shall have grounding the same as the service equipment.
(7) Current limit devices. Conductors shall be fused or protected to their current-carrying capacities. More than six disconnect switches are not to be in the hot truck or generator unless a main switch is provided. Fuses or current-limiting devices may not be installed in the neutral or grounding conductors. Motors and lighting circuits shall be fused separately.
(8) High voltage lines. The outlets or electric power lines carrying more than 120 volts shall be clearly marked to show their voltages.
(9) Outdoor apparatus and wiring. Electrical apparatus and wiring located outdoors shall be of such quality and so constructed or protected that exposure to weather will not interfere with its normal operation.
(10) Elevated lines. Elevated power lines crossing access or other roads within the grounds of a carnival, fair, or amusement park shall be so suspended as to provide minimum vertical clearance of 15 feet from the road surface and minimum horizontal clearance of three feet on each side of the normal passage space of vehicles.
(11) Bus bars. Bus bars shall be located low or near the bottom of the cabinet. Separate bus bars shall be provided for grounding neutral and phase conductors.
(12) Color codes. Color code requirements are as follows:
a. Color codes painted on the inside and outside of the box, but not on contact surfaces of bus bars, are to be:
1. | Ground—Green or green with a yellow strip | 1st Phase—Black 2nd Phase—Red
2. | Neutral—White or natural gray | 3rd Phase—Blue
3. | On a four-wire delta-connected secondary, the phase conductor having the higher voltage to ground shall be orange.
b. These color codes are to carry on through all connected wiring from service through portable power outlet and terminal boxes. Buses may not be less than 200 ampere capacity. The load terminals in a switchboard or panel board shall be located so that it will be unnecessary to reach across or beyond a live bus (hot bus) to make a local connection.
(13) Portable power outlet and terminal box. Boxes are to be raintight and kept locked during the time when the general public is in the area. Wood boxes may be used if insulated on all sides with fire-resistant material or painted with insulating varnish. The service power shall be connected to the box by receptacles mounted on the exterior walls which include the safety grounding. The distribution within the box shall be accomplished by neutral terminal bars and circuit breakers or fuses. The branch circuits which include the equipment safety grounding shall obtain their power through receptacles mounted on the exterior of the box. The exterior openings of the receptacles shall be at least six inches above ground level and provided with a protective cover, draining eave or canvas, that will avoid the possibility of rain on the receptacle. If it is required to run conductors directly through an opening on the wall of the box for additional service or to obtain required ampacity, the openings shall be color coded and shall be sized to prevent public accessibility to the interior of the box. The fuses or breakers, in the boxes, shall be secured permanently in place, and all connections to the bus bars within the boxes are to be made with threaded screws and lugs of the proper size to fasten wiring in place.
(14) Power sources. Electrical power sources shall be located in a manner permitting proper maintenance and shall be protected either by guards, fencing or enclosure to prevent exposure to hazard and to secure the equipment.
