ELECTRICAL SYSTEM GENERAL DESIGN FOR ALTERNATING CURRENT a The following guidelines shall apply to the 120/ 240 VAC system installation: General L L Any fixed line voltage power source producing alternating current (ac) line voltage shall 13 produce electric power at 60 cycles plus or minus five ( 5) cycles. J Except where superseded by the requirements of NFPA 1901, all components, equipment and d installation procedures shall conform to NFPA 70, National Electrical Code ( herein referred to E t as the NEC). Line voltage electrical system equipment and materials included on the apparatus shall be a listed and installed in accordance with the manufacturer's instructions. All products shall be used only in the manner for which they have been listed. Grounding Grounding shall be in accordance with Section 250 -6 " Portable and Vehicle Mounted Generators" of the NEC. Ungrounded systems shall not be used. Only stranded or braided copper conductors shall be used for grounding and bonding. An equipment grounding means shall be provided in accordance with Section 250 -91 Grounding Conductor Material) of the NEC. Page 70 of 93 The grounded current carrying conductor (neutral) shall be insulated from the equipment grounding conductors and from the equipment enclosures and other grounded parts. The neutral conductor shall be colored white or gray in accordance with Section 200 -6 ( Means of Identifying Grounding Conductors) of the NEC. In addition to the bonding required for the low voltage return current, each body and driving or crew compartment enclosure shall be bonded to the vehicle frame by a copper conductor. This conductor shall have a minimum amperage rating of 115 percent of the nameplate current rating of the power source specification label as defined in Section 310 -15 amp capacities) of the NEC. A single conductor properly sized to meet the low voltage and line voltage requirements shall be permitted to be used. All power source system mechanical and electrical components shall be sized to support the continuous duty nameplate rating of the power source. Operation L Ld Instructions that provide the operator with the essential power source operating instructions, a including the power -up and power -down sequence, shall be permanently attached to the J apparatus at any point where such operations can take place. Provisions shall be made for quickly and easily placing the power source into operation. The 0 control shall be marked to indicate when it is correctly positioned for power source operation. Any control device used in the drive train shall be equipped with a means to a prevent the unintentional movement of the control device from its set position. L s A power source specification label shall be permanently attached to the apparatus near the operator's control station. The label shall provide the operator with the information detailed in a Figure 19 -4. 10. co M N Direct drive ( PTO) and portable generator installations shall comply with Article 445 Generators) of the NEC. U_ Overcurrent protection NV d Q The conductors used in the power supply assembly between the output terminals of the power source and the main over current protection device shall not exceed 144 inches. ( 3658 mm) in L length. L For fixed power supplies, all conductors in the power supply assembly shall be type THHW, THW, or use stranded conductors enclosed in nonmetallic liquid tight flexible conduit rated for Jo a minimum of 194 degrees Fahrenheit ( 90 degrees Celsius). d E For portable power supplies, conductors located between the power source and the line side of the main overcurrent protection device shall be type SO or type SEO with suffix WA flexible cord rated for 600 -volts at 194 degrees Fahrenheit ( 90 degrees Celsius). Wirinq Methods Fixed wiring systems shall be limited to the following: Metallic or nonmetallic liquid tight flexible conduit rated at not less than 194 degrees Fahrenheit (90 degrees Celsius) or Type SO or Type SEO cord with a WA suffix, rated at 600 volts at not less than 194 degrees Fahrenheit (90 degree Celsius) Page 71 of 93 Electrical cord or conduit shall not be attached to chassis suspension components, water or fuel lines, air or air brake lines, fire pump piping, hydraulic lines, exhaust system components, or low voltage wiring. In addition the wiring shall be run as follows: Separated by a minimum of 12 inches ( 305 mm), or properly shielded, from exhaust piping Separated from fuel lines by a minimum of six ( 6) inches ( 152 mm) distance. Electrical cord or conduit shall be supported within six (6) inches ( 152 mm) of any junction box and at a minimum of every 24 inches (610 mm) of continuous run. Supports shall be made of nonmetallic materials or corrosion protected metal. All supports shall be of a design that does not cut or abrade the conduit or cable and shall be mechanically fastened to the vehicle. Wiring Identification All line voltage conductors located in the main panel board shall be individually and permanently identified. The identification shall reference the wiring schematic or indicate the final termination point. When prewiring for future power sources or devices, the unterminated ends shall be labeled showing function and wire size.
