If your generator is to be used outdoors, especially in hurricane prone areas you need a generator enclosure.
Once you’ve decided to install your genset outdoors in an enclosure, the overall cost and ease of
installation will be contingent upon the physical location of all elements of the system: generator set, fuel tanks and accessories. Several types of enclosures are on hand, including weather-protective, sound-attenuating and walk-in.
• A Walk-in. This term covers a wide variety of enclosures that are custom-built to a specific
application. Walk-in enclosures often include sound attenuation, as well as space for power switching and monitoring equipment, lighting, fuel tanks and other equipment. They can also accommodate insulating and heating capability. Walk-in enclosures may be treated as a building by local inspection officials.
• Sound-attenuating. Sound-attenuating enclosures may be specified when noise reduction is needed to
meet local ordinances. These enclosures are generally larger and more costly than strictly weather-protective enclosures due to the design features required to reduce generator set noise.
• Weather-protective. While all metal enclosures provide weather protection, these basic enclosures
only secure the generator set and provide protection from the elements. They do not retain heat or hold
temperatures above ambient in cold weather or provide cooling beyond the ventilation and airflow
offered by incorporated louvers or perforated panels. Sound attenuation is minimal and, due to their tight fit, access panels or doors are required for maintenance and inspections.
