Detailed Solution
Download Solution PDFThe correct answer is option 1.
In the design procedure for electrical installations in commercial buildings, the first step must be understanding how much power the building will need. This involves:
- Estimating electrical loads: Lighting, HVAC, elevators, office equipment, etc.
- Calculating peak demand: Helps size transformers, panels, and feeders correctly.
- Planning for future expansion: Ensures flexibility without major redesign.
Only after this analysis can an engineer begin selecting conductor sizes, designing protective systems, specifying panel boards, switchgear, and layout. Without a load analysis, you risk installing an unsafe or non-functional system. It can lead to power outages, fire hazards, or legal violations.
