Professional review

Major standby-power proposals should be reviewed by qualified electrical and fuel professionals.

Important: Costs, codes, permits, inspection duties, accessibility rules, environmental requirements and insurance conditions vary by country, province or state, municipality, building use, equipment type, installation date and project scope. Qualified local professionals and the authority having jurisdiction must determine what applies. Generator exhaust can produce deadly carbon monoxide. Electrical backfeed, fuel, fire, noise and exhaust hazards require qualified design and installation. Never operate a portable combustion generator indoors or in a partly enclosed area.
