Conduit or cable tray: the choice is yours

Abstract

The author describes how the choice of which type of power and control cable raceway to utilize in the pulp and paper industry is usually based on several factors. Tray systems provide an economical means of providing a stable raceway for power and control wiring. They can be utilized to provide the requirements of most projects. Conduit can achieve the same results at a higher cost in large cable installations. For smaller projects where there are not as many wires then the conduit system is the most economical. Conduit has the distinct advantage of keeping in compliance with the NEC. Once the system has been installed, the possibility of overfilling the system is small. The tray system is a challenge to keep in compliance with the NEC.<>
