Design and Specification Considerations

  1. Voltage and Current Ratings

    • Ensure all components are rated for the operating voltage and expected current loads.

  2. Short Circuit Ratings

    • Components must withstand the maximum fault current levels anticipated in the system.

  3. Environmental Conditions

    • Design for temperature extremes, humidity, and potential contaminants (dust, salt, etc.).

  4. Safety and Protection

    • Compliance with relevant standards (e.g., IEC, IEEE).
    • Adequate insulation and spacing to prevent accidental contact and arcing.

  5. Accessibility and Maintainability

    • Design for easy access to components for inspection, testing, and maintenance.
    • Modular designs for quick replacement of faulty parts.
