Current through Register Vol. XLI, No. 43, October 25, 2024
Section 64-41-6 - Electrical Distribution (Refer to Section 11 of the Mobile Home Regulations)6.1. Preferably, distribution lines should be installed in underground conduits. Underground lines provide a much neater appearance and permit more efficient use of available land than do overhead lines. Underground lines should be placed at least 18 inches below the ground surface and at least 1 foot radial distance from water, sewer, gas, or communication lines.6.2. If overhead power lines are installed, they should be at least 18 feet above streets or roadways. A minimum horizontal clearance of at least 3 feet is necessary between overhead lines and structure. Electrical systems of mobile home developments should be calculated on the basis of at least 16,000 watts (at 120/240 volts) for each mobile home. Since all mobile homes, however, do not use the maximum amount of electricity at once, demand factors should be checked with the power company supplying the mobile home park.6.3. A properly grounded, weatherproof receptacle capable of supplying at least 100 ampere current at 115/230 volts should be provided for each mobile home lot. Those mobile homes, however, that are equipped with air conditioners, automatic washers and dryers, or other power consuming appliances may need 100 ampere current at 120/240 volts. The attachment plug, connectors, and mating receptacles should be of a 3-pole, 4-wire grounding type complying with ANSI C73.1.6.4. The point of the electrical connection for the mobile home should be within the area of the mobile home stand and approximately 40 feet from the front of the stand.6.5. Circuit breakers or other overcurrent protective devices and disconnecting switches should be provided in a convenient location for each mobile home to be served. The outlet receptacles should be within 25 feet of the overcurrent protective devices in the mobile home.6.6. All exposed noncurrent carrying metal parts of mobile homes and equipment should be grounded by means of an approved grounding conductor run with branch circuit conductors or other approved method of grounded metallic wiring. The neutral conductor should not be used as an equipment ground for mobile homes or other equipment.6.7. Lighting 6.7.1. Adequate lighting should be provided for all streets, walkways, buildings, and other facilities subject to nighttime use. Illumination should be provided in accordance with local and power company requirements; where none exist, the recommendations in the Standard Lighting Guide of the illuminating engineering society may be applied.6.7.2. Because of the safety hazards associated with high density developments, such as mobile home developments, it is recommended that an average illumination level of at least 0.6 foot candles and a minimum illumination level of 0.1 foot candle be maintained on all streets. Potentially hazardous locations, such as street intersections and steps or stepped ramps, should be individually illuminated, with a minimum level of 0.3 foot candles.
