The proper installation of a distribution box involves placing it at the right height to ensure safety and convenience. 7 meters) high makes it easily accessible without the need to bend or stretch excessively. (1) Elevator driving machines, motor generator sets, controllers, and auxiliary control equipment shall be installed in a room or enclosure set aside for that purpose. This height also safeguards the box from potential. The work space shall be clear and extend from the grade, floor or platform to a height of 6 1 / 2 feet or the height of the equipment, whichever is greater. The electrical equipment itself may have a height that is less than 6 1 / 2 feet, but if it is mounted so the top of the equipment is higher. Overcurrent devices and disconnects must be located in machine or control spaces, be lockable and provide a single means to disconnect ungrounded conductors, with selective coordination for multi-elevator feeders.
