This standard establishes design tests and specifications for high-voltage (above 1000 V) distribution class enclosed single-pole air switches and associated accessories with rated voltages up to 8.3 kV. All of these devices are intended for use on alternating current distribution systems. These design tests and specifications apply to the following specific types of equipment: a) Distribution class enclosed single-pole air switches b) Supports@ mountings@ fuse hooks@ and tongs@ all of the type used exclusively with distribution class enclosed single-pole air switches c) Distribution class enclosed single-pole air switches used in enclosure packages Purpose This standard contains the specifications and minimum testing requirements for distribution class enclosed single-pole air switches with rated voltages up to 8.3 kV. Such standardization is needed to help ensure uniform minimum product testing for devices within the document scope. Test areas covered are based on historical experience.
