These requirements cover electric motors and generators for permanent installation and use in hazardous (classified) locations, Class I, Division 2, Groups A, B, C, and D, and Class II, Division 2, Groups F and G, in accordance with the National Electrical Code, NFPA 70. <br>These requirements cover both horizontal and vertical machines that have fractional and integral horsepower ratings. <br>These requirements do not cover intrinsically safe motors. <br>A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this Outline of Investigation, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of this Outline of Investigation. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this Outline of Investigation cannot be judged to comply with this Outline of Investigation. Where considered appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Outline of Investigation.
