For housing terminal blocks, relays and other electrical devices
Indoors or outdoors in damp, wet, dusty, corrosive, hazardous locations
Where exposure to frequent or heavy rain, water, spray, moisture and humidity is common, such as: offshore drilling facilities, cooling towers, coal preparation and handling facilities and sewage and waste water treatment
In areas which are hazardous due to the presence of hydrogen or gases and vapors of equivalent hazard such as found in process industries, missile bases and gas manufacturing plants
