Yes, the electrical equipment installed in an enclosure or small building housing 2- 125kva diesel generators needs to be designed for a classified area.The presence of diesel generators and their day tanks creates a potential for flammable vapors due to fuel leaks, spillage, or combustion byproducts. These vapors can accumulate in the enclosed space, posing a risk of fire or explosion.To mitigate this risk, the electrical equipment within the enclosure must be designed and installed to meet the requirements for classified areas, as defined by electrical codes and standards such as the National Electrical Code (NEC) or the Canadian Electrical Code (CEC).The specific classification of the area depends on the type of fuel used by the generators, the ventilation conditions, and the presence of other potential ignition sources. For example, the area around diesel generators with day tanks is typically classified as Zone 2, which requires electrical equipment that is certified for use in potentially explosive atmospheres.The following electrical equipment should be designed for classified areas when installed in an enclosure or small building housing diesel generators: Lighting fixtures Electrical panels Wiring and cables Switches and controls* Motors and other electrical devicesBy using electrical equipment that is specifically designed for classified areas, the risk of fire or explosion can be minimized, ensuring the safety of personnel and the proper operation of the generators.
