AC pre-charging techniques are provided for pre-charging the DC bus on a motor drive. AC pre-charging techniques involve pre-charge circuitry including a manual switch, an automatic switch, and pre-charge control circuitry to switch the automatic switch between pre-charge and pre-charge bypass modes in response to an initialized pre-charge operation, input voltage sags, etc. In some embodiments, the pre-charge operation may be initialized by switching the manual switch closed. In some embodiments, the pre-charge operation may also be initialized by a detected voltage sag on the DC bus. The pre-charge circuitry may also be configured to disconnect a motor drive from the AC power supply under certain fault conditions.

An electrical bus assembly includes a frame and a plurality of bus bar carriers connected to the frame. The bus bars are supported by the bus bar carriers in parallel spaced-apart relation. A first retainer cap is secured to a first one of the plurality of bus bar carriers located adjacent a first end of the frame. A second retainer cap is secured to a second one of the plurality of bus bar carriers located adjacent a second end of the frame. The first and second retainer caps limit axial movement of the bus bars relative to the plurality of carriers sufficiently to prevent escape of the bus bars from the carriers. A bus bar connector is also disclosed for supplying power to or from the bus bars. An electrical bus system includes a first and second bus bar assemblies and a jumper connector assembly.
