BS PD IEC/TS 62993:2017
Guidance for determination of clearances, creepage distances and requirements for solid insulation for equipment with a rated voltage above 1 000 V AC and 1 500 V DC, and up to 2 000 V AC and 3 000 V DC
IEC TS 62993, which is a Technical Specification, gives guidance to technical committeeswhich deal with equipment having a RATED VOLTAGE of more than 1 000 V AC and up to2 000 V AC, or a RATED VOLTAGE of more than 1 500 V DC and up to 3 000 V DC. RATEDVOLTAGES up to 1 000 V AC and 1 500 V DC, as well as higher or lower internal voltages, arecovered by IEC 60664-1.
