Table 2 in Chapter 9, which covers both manual and machine bending of the raceway, provides field bend requirements for conduit and tubing.The NEC fill calculations affect conduits. Due to conduit pulling requirements NEC reduces the percentage of the cross sectional area of a conduit that can be filled according to the cable count in the conduit. The NEC fill calculations affect instrument and control cables and trays. Due to weight and heat considerations a maximum fill depth ...
