    2.     Step 1: Identify the isolators present in the system and determine if each needs functional, basic or reinforced isolation.
    3.     Step 2: Determine the system voltage.
    4.     Step 3: Determine the requirement for temporary overvoltage and impulse/surge voltage for each isolator according to the IEC62109-1 standard.
    5.     Step 4: Determine the clearance required from every isolator used in the design.
    6.     Step 5: Determine the working voltage (both peak and RMS) based on the actual operating condition of the isolator.
    7.     Step 6: Determine creepage based on the working voltage according to IEC62109-1.
