Another wirin method that may find conditional use in elevator wor is fleible cords and cables that are components of listed euipment and used in circuits operatin at root mean suare or less or C or less.
Traveling cable is typically mounted in the elevator hoistway, where each end is terminated, and alternately takes the full load of the suspended cable as the car moves up and down.
Comprehensive guide to cable tray systems requirements: tray types, materials, loading, supports, bonding, routing, and best practices for safe electrical cable management.
Cable tray types, supports (types and spacing) and securing systems are selected and designed taking into consideration the weight of the cables including reserves, increased by a dynamic shock load of
Cable trays feature flexibility unmatched by conduit, as cables are easier to mark, remove and find in cable trays. Cable trays are avail-able in a number of different configurations, including ladder,
The choice of method should be discussed with a local inspector. The best decision may be to extend only the cables, creating a discontinuity in the cable tray.
Explore the essentials of elevator cable in our comprehensive guide, covering wire specifications, strands, lengths, and more for optimal performance and safety.
Ladder tray should be mounted far enough off the floor or roof to allow the cables to exit through the bottom of the tray. If strut is used as a cross support, mount the strut directly to the roof or floor.
Generally, conductors and cables in or on an elevator or in the hoistway (other than traveling cables) must be installed in rigid metal conduit, intermediate metal
