Abstract
High voltage motor contactors and associated equipment are arranged within upper and lower compartments that are interlocked with the external operator handle to prevent access when the contactors are electrically energized. Low voltage devices used in association with the contactors to provide total motor control function are housed within upper and lower cabinets arranged on the upper and lower compartment doors. An interlock defeat assembly is mounted within the low voltage cabinets to allow emergency access to the compartments while the contactors are still energized.
