ABSTRACT:
Disclosed is an active cooling system for a terminal box associated with a gas cooled electric powered generator. A manifold system is provided around the periphery of the terminal box and is fluidly connected to the inlet of the power generator cooling fan. A plurality of holes spaced around the manifold system permit a lower pressure at the fan inlet to draw cooling gas through the generator along the walls and floor of the terminal box and into the manifold. This increased cooling prevents temperature damage to the terminal box, and its walls and floor and components located therein and reduces terminal box burn hazard.
