Preventative Measures for Future Installations

Use cable ties, Velcro straps, or clips to o keep wires organized inside contintion boxes and cable trays. In conduit, pull wires in convence: start wich the strongest drivest and addfleksible ones later. Always foe a pull string behind for future addisetions.
