Key Considerations When Selecting a Generator for Commercial Facilities

Generator selection starts with a documented schedule of the loads requiring backup power. The schedule should reflect the building’s operational and safety requirements, including any designated HVAC, elevator, fire-protection and lighting loads. Required generator capacity is then assessed from that scope.

Starting currents and load characteristics can affect selection as much as steady running demand. Installation planning also considers combustion air, radiator discharge, exhaust routing, acoustic treatment and maintenance access.

Fuel storage, expected operating duration and refuelling access should be coordinated with the site layout. Automatic transfer switches, earthing and UPS integration belong in the electrical design, with operating sequences checked during commissioning.

ASIF supplies generator solutions powered by Perkins and Cummins engines and coordinates them with UPS and distribution systems where included in scope. The quotation should identify the required duty rating, load schedule and installation requirements.
