Standard for creepage clearance in electrical distribution boxes
Since April 1997 the sising of clearance and creepage distances has been covered by DIN VDE 0110 part 1 “Insulation coordination for electrical equipment in low-voltage systems”. DIN VDE 0110 part 1 contains the modified edition of IEC Report 664-1 (see also IEC 664-1/Oct 1992). The design data resulting from these. The culprit is often a misapplication of creepage and clearance rules, where a designer assumed “12 kV switchgear” meant one number when the standard actually required another based on altitude, pollution, and insulation material. Note that two parts of insulating material close together, even if glued, don't count as a one-piece part, meaning that the Cl path passes through the ...
