20. For flush mounted panels, run empty conduits from panel to accessible spaces above. Install a minimum of one ¾" conduit for every 3 single pole spare circuit breakers or spaces, or fraction thereof.

21. Running Threads: Do not use running threads. Where such device is needed, use rain tight unions or concrete tight couplings.

22. The entire electrical raceway system shall be bonded and form a continuous metallic electrical conductor from service point to every box and shall be terminated with ground bushings connected to the ground bus. Conduits entering enclosures shall be fitted with insulated grounding bushing. All grounding bushings shall be tied to the grounding system with properly sized bonding conductors per the NEC Code.

23. Connection to steel conduit from PVC shall be made with approved threaded adapters.

24. All conduits which are installed shall be capped during construction to prevent the entrance of foreign material.
