Load List

List all machines, motors, compressors, pumps, HVAC, lighting and office loads.

Large motors may need higher starting capacity than their running load suggests.

Plan margin for future expansion and site operating conditions.

Can I size a factory generator from monthly electricity bill?

No. You need equipment load and starting current data, not just monthly energy use.

Should I use kW or kVA?

Both matter. kW is real power; kVA includes power factor and apparent power.
