Key Factors for Choosing a Contractor Generator
Power Output and Surge Capacity
Your generator’s wattage dictates what you can run simultaneously. Running watts are for continuous operation, while starting watts handle the initial surge from motors. For contractors, this means calculating the total draw of your heaviest tools, like air compressors or large saws, plus ancillary equipment.
Undersizing leads to tripped breakers and damaged tools. Oversizing wastes fuel and money. A generator with a robust surge capacity, like the models we reviewed, ensures you can start multiple motor-driven tools without issue, a common scenario on any active site. For more on sizing for continuous needs, see our guide on generators for long power outages.
Fuel Type and Runtime Efficiency
Fuel strategy impacts your operating cost and logistical planning. Traditional gasoline generators are powerful but require fresh fuel management. Dual-fuel capability, as seen in one of our picks, offers critical flexibility.
Propane stores indefinitely, burns cleaner, and is often safer to keep on site. A long runtime at a given load reduces refueling interruptions, keeping crews focused on the task. Prioritize models with large fuel tanks and efficient engines to maximize work time between stops.
Durability and Job Site Portability
<!–A contractor’s generator faces bumps, weather, and constant movement. A rugged, open-frame design often provides the best balance of protection and cooling. Look for sturdy construction with quality materials that can withstand transport in a truck bed.
Portability is about more than wheels. Consider the unit’s weight, wheel size for rough terrain, and handle design. Large, never-flat tires and a robust folding handle make moving a heavy unit across uneven ground significantly easier, saving time and strain. Explore all Briggs & Stratton Generators to see the full range of durable options.

Frequently Asked Questions
What size generator do I need for a standard contractor’s job site?
Start by listing all tools and equipment you’ll run concurrently, focusing on those with electric motors. Add their running watts together, then identify the single tool with the highest starting wattage. Your generator’s running wattage must exceed the total running load, and its surge wattage must cover that highest starting draw plus the running watts of other tools. A unit in the 5000 to 8000 running watt range, like those reviewed, typically handles a robust array of professional tools.
Why is CO Guard technology important for contractors?
<!–Contractors often operate in garages, under canopies, or near building openings where exhaust can accumulate. Carbon monoxide is odorless and deadly. CO Guard technology actively monitors the air and automatically shuts down the generator if dangerous levels are detected, providing a critical layer of protection for you and your crew that standard generators lack.
Can I use a dual-fuel generator to power all my tools?
<!–Yes, a quality dual-fuel generator like the Briggs & Stratton 6250W model delivers full power on both gasoline and propane. You will experience a slight reduction in wattage output when running on propane compared to gasoline, which is normal. This flexibility allows you to choose fuel based on availability, cost, or storage needs without compromising your core power requirements. For other powerful portable options, consider our review of Briggs & Stratton 6500W portable generators.
How do I maintain a generator for reliable contractor use?
<!–Regular maintenance is key for reliability. Always use fresh fuel and a fuel stabilizer for gasoline, and run the generator dry before storage. Check and change the oil according to the manufacturer’s schedule, which is more frequent under heavy use. Keep the air filter clean and inspect spark plugs periodically. Store the unit in a clean, dry place, and exercise it monthly under load to keep components lubricated and the battery charged if it has an electric start.
