Do not use the MH as a 90 degree bend in cable installations. Z. Ream and bush the ends of the metallic conduit: AE Project #: <> 27 0543 ‐ 8 UH Master: 03.2020 < #> 1. 2. Insulated metallic bushings for 1 ¼‐inch conduit and larger Insulated metallic bushings with grounding lugs for conduit entering Network Facilities (NFs). AA. After conduit duct installation has been completed and concrete has set, pull “D” test mandrel through all new conduit ducts to verify duct integrity and ensure smooth interior surfaces free from burrs or obstructions that might damage cable sheaths. BB. Following mandrel testing, draw cylindrical wire brush with stiff bristles through each conduit to clean the conduit and remove any concrete, dirt or other obstructions. CC. Stub out conduits into NFs, and cabinets only enough to attach connector and bushings with grounding lugs, except conduits shall rise a minimum of 6 inches above the finished floor. DD. Install new pull rope in all new conduit and extend three feet into each building space. EE.
