  • SCOPE

    1 Scope

    1.1 These requirements address the electric shock, fire, and casualty aspects associated with the mechanical performance and the electrical features of portable engine-driven generator assemblies.

    1.2 These requirements cover internal combustion engine-driven generators rated 15 kW or less, 250 V or less, which are provided only with receptacle outlets for the AC output circuits. The generators may incorporate alternating or direct current generator sections for supplying energy to battery charging circuits.

    1.3 Generators covered by this standard are normally used by persons other than service personnel.

    1.4 These requirements cover open ventilated generators having ventilating openings that permit the passage of external cooling air over or around the windings, or both.

    1.5 These requirements cover generator components and combinations of such components.

    1.6 These requirements do not cover generators for use in hazardous locations as defined in the National Electrical Code, NFPA 70.

    1.7 These requirements do not cover generators for marine use. That equipment is covered by the Standard for Marine Electric Motors and Generators, UL 1112.

    1.8 These requirements do not cover generators intended for installation in recreational vehicles. That equipment is covered by the Standard for Engine-Generator Assemblies for Use in Recreational Vehicles, UL 1248.

    1.9 These requirements do not cover generators intended for stationary use. That equipment is covered by the Standard for Stationary Engine Generator Assemblies, UL 2200.

    1.10 These requirements do not cover generator assemblies as part of welding and plasma cutting machines. That equipment is covered by the Standard for Safety for Transformer-Type Arc-Welding Machines, UL 551, or the Standard for Arc Welding Equipment; Part 1: Welding Power Sources, UL 60974-1.

    1.11 These requirements cover products fueled by flammable and combustible liquids such as gasoline and diesel fuel, including gasoline with small amounts of additives such as detergents, solvents for detergents and anti-icing chemicals, and gasoline with up to 15% ethanol or methyl tertiary butyl ether (MTBE).
