Verified Supplier Network

Do not size a generator by adding up nameplates alone. Add the loads that run together, then leave about 30 percent headroom, because motors draw several times their running current when they start.

If you are unsure, send us your equipment list and we will help check the size before you commit.

Typical Loads for a 800kVA Generator

About 320 x 1.5 hp split air conditioners (about 1.4 kW each running)
About 2240 x office workstations with monitors (about 0.2 kW each running)
About 121 x 5 hp three-phase borehole pumps (about 3.7 kW each running)
About 59 x 10 hp three-phase motors (about 7.5 kW each running)
About 20 x 30 hp three-phase motors (about 22 kW each running)
About 5 x 100 hp three-phase motors (about 75 kW each running)

Sizing Rules of Thumb

Add up loads that run at the same time, then multiply by 1.25 to 1.3
Start your biggest motor first, then the smaller ones
Three-phase motors start more smoothly on a generator than large single-phase loads
Allow for future growth if you expect to add equipment

When to Size Up

Large motors starting direct-on-line without a soft starter
Welding machines and compressors that cycle on and off
Sensitive electronics that need a clean, stable supply
Loads that will grow within a couple of years

Frequently Asked Questions

Can a 800kVA generator run my whole building?

It depends on the connected load. At about 640 kW with 30 percent headroom, it can carry about 448 kW of simultaneous load. Send us your equipment list and we will check.
