NFPA 37 requirements dictate the clearance that a generator should have between its installation location and buildings, windows, and shrubs. For a full list, see the NFPA 37 site:. . If your generator is expected to be in temperatures lower than -20 o F (-29 o C) consult the generator sets factory, a cold weather package may be required. Where strong prevailing winds are anticipated, face the engine end away from the wind. Typical Outside Small Generator Installation. . The National Electrical Code (NEC) establishes strict clearance requirements for generators to ensure safety and operational efficiency. The exhaust gets extremely hot and remains hot after shutdown. Flammable material may ignite and burn from the heat of the exhaust system.

o pull a rated full load between 40°C (104°F) and 50°C (122°F). The cooling systems are designed to operate in these ambients, and when enclosed, he canopy design has to allow the correct amount of air in and out. While a generator's rated power output will be reduced as the ambient air temperature increases above 21°C (70°F), the
Clearance requirements help ensure the generator is operated at a safe distance where heat and fumes will not cause fires or health hazards. The exhaust gets extremely hot and remains hot after shutdown. Flammable material may ignite and burn from the heat of the exhaust system.
Proper installation of electrical generator systems is essential for reliable operation. Most electrical generator systems utilize a unit-mounted radiator system with an air-moving fan to provide cooling and robust operation. This white paper provides guidelines on best practices to ensure adequate cooling airflow associated with installations.
Its requirements limit the spacing of the generator from a structure or wall. The unit must be located where it's readily accessible for maintenance, repair, and first responders. Minimum clearance requirements are for adequate airflow, maintenance, and safety. For a complete and updated list, see the NFPA 37 web page.
