For IEC designed control panels, the below suggested cable sections are calculated according to
60364-5-52 (Electrical installations of buildings - selection and erection equipment - current-carrying
capacities in wiring systems).
Standard conditions refer to multi core copper cables with 70˚C PVC or 90 °C XLPE/EPR insulation in
cable conduits or cable trunking systems (installation method B2) at 30˚C ambient temperature and
operating at nominal voltage. The cables may not be grouped with other power circuits or cables.
Worst case conditions refer to:
• Ambient temperature > 30˚C (86 ˚F)
• Cables in closed raceway, conduit or trunking system (installation method B2) at 46 ˚C ambient
temperature
• Cables not grouped with other cables
Fuse calculations for IEC are done according to 60364-4-43 electrical installations of buildings, part 4:
protection for safety- section 43: protection against overcurrent. Fuse sizes are calculated in order to protect
the cable against short circuit. Fuse type aM is recommended but gG/gL is also allowed.
