NOTES:
1. Conductors for grounding shall be connected to steel framework
that has been cleaned to base metal by use of bonding plates
having contact area of not less than 8 square inches or by welding
or brazing. Drilling and tapping the steel structure to accept a
threaded connector is also an acceptable method.
2. If steel framework is to be drilled and tapped to accept threaded
connector, the threaded connector shall be galvanized and have at
least 5 threads fully engaged and secured with a jam nut to the
steel framework.
3. Bends in the conduit shall not be less than the minimum bending
radius for the cable contained in the conduit.
4. Catwalk and handrail design and installation shall comply with AISC,
