摘要： A bus cooling fan that operates without an external electrical power supply. The fan is positioned proximate two bus bars of a polyphase electrical system. The fan includes a rotor supporting fan blades and mounted on an axle. The axle is supported by cross-braces in a shroud surrounding the rotor. The shroud is open at the ends. The fan is fabricated of non-ferrous, non-conducting material with the exception of the rotor. The bent rods which interact with the electromagnetic field created by the current-carrying bus bars of the polyphase electrical system to make the rotor function as an induction motor when the fan is placed proximate two bus bars.

摘要： An electrical enclosure having continuous front accessible dedicated wiring compartments. The dedicated wiring compartments provide the installer with easily accessible front wiring compartments. Each dedicated wiring compartment contains wiring for a specific function. The dedicated wiring compartments are configured to provide a continuous front accessible wiring compartment for multiple enclosures installed immediately adjacent one another. Horizontal frame members of the electrical enclosure provide a significant part of each dedicated wiring compartment.
