4. CONDUIT TERMINATION FITTINGS OR BULKHEAD FEED THRU FITTINGS MAY BE USED FOR CABLE EXIT IN LIEU OF STANDARD SWAGE TUBES.

5. MEASURE AND CUT SHIELDING CONDUIT TO LENGTHS REQUIRED.

6. INSTALL CABLE SHIELD GROUNDING MATERIALS AND FLEXIBLE SHIELDING CONDUIT AS SPECIFIED HEREIN. WEATHERPROOF ALL FITTINGS AS SPECIFIED FOR CORROSION PROTECTION.

7. ALL FITTINGS ARE DEPICTED PRIOR TO WEATHERPROOFING.

8. AFTER COVERS ARE INSTALLED, WIREWAY TRUNK SHALL BE PRIMED AND PAINTED.
