19、ature and voltage, exposure to oil or grease, and other conditions of service to which the wiring is subjected. 8.3 Wiring shall be protected against mechanical damage by: a) Enclosing it in the body of the truck; or when mounted on masts, booms, lifts or similar parts, the wiring shall be installed
20、 so as to reduce the likelihood of mechanical damage and kinking; b) Enclosing it in metal raceway, such as armored cable, rigid metal conduit, or electrical metallic and nonmetallic tubing, exible nonmetallic conduit or nonmetallic insulated tubing; or c) Other suitable method in which the wiring i
21、s protected sufficiently against mechanical damage. 8.4 Wiring and cables shall be installed with means for maintaining clearance from moving parts, hot engine parts, exhaust systems and fuel systems, and shall not be supported on surfaces that are subjected to accumulation of oil or grease as a res
22、ult of servicing. 8.5 Wiring and cables shall not be located such to allow exposure to drippage of gasoline, diesel, oil, or grease, and shall not be supported on oil- or grease-retaining surfaces. 8.6 If an audible electrical warning device is employed, its coil and other electrical parts shall be
23、enclosed in metal or an equivalent material. Among the factors that are to be taken into consideration when judging the equivalency of a nonmetallic enclosure are: a) The mechanical strength, b) Resistance to impact, c) Moisture-absorptive properties, d) Flammability, and f) Resistance to distortion at temperatures to which the material is subjected under conditions of normal or abnormal usage.
