Sample interview questions: Can you explain your understanding of electrical load calculations and capacity planning?
Sample answer:
Electrical Load Calculations:
- Determine the power consumption of electrical devices through wattage ratings.
- Consider the simultaneous operation of appliances and the diversity factor.
- Utilize empirical methods, such as the NEC Code tables, to estimate typical loads for various building types.
- Employ software tools or perform manual calculations to determine the total connected load.
Capacity Planning:
- Assess the current load demand and project future growth based on load forecast analysis.
- Design electrical systems with adequate capacity to meet both present and anticipated requirements.
- Consider the maximum demand factor to determine the peak load the system can handle.
- Determine the appropriate service size, transformer rating, and conduct… Read full answer
