Best generator for construction and jobsites

On a jobsite, a generator has to start a table saw or an air compressor, run all day on one tank and survive being thrown in a truck. We kept the open-frame models with at least 3,000 running watts.

How to choose

Tools pull big starting currents

A 10-inch table saw can need 4,000 W or more to start; a 2 HP air compressor 5,000 W or more. Size on the biggest tool you start under load.

Outlets

GFCI-protected 5-20R duplex outlets are standard. An L5-30R or L14-30R outlet feeds a spider box for several crews.

Mistakes to avoid

  • Running long, thin extension cords: the voltage drop overheats tool motors. Use 12- or 10-gauge cords.

Frequently asked questions

What size generator do I need for a jobsite?

3,500 to 5,000 running watts for one or two power tools; 7,500 W and up for compressors, several crews or a spider box.

Are inverter generators good for construction?

They work for light tools and chargers, but open frames are more rugged and cheaper per watt for heavy tools.

Do jobsite generators need GFCI outlets?

OSHA requires ground-fault protection for temporary power on construction sites: GFCI outlets or GFCI cords.
