Specifies measures to prevent fire and thermal hazards under both normal and single-fault conditions. It defines the necessary spacing (clearance and creepage

"Look at ," Elias pointed to the screen. "IEC 62477-2 has very specific requirements for clearances and creepage distances, but it also dictates how we handle insulation coordination during operation ."

This is the core of the standard. It defines the necessary spacing (clearance and creepage distances) and insulation thickness required to prevent arcing and accidental contact at voltages up to 5000 V DC.
