4. Shape or style: Conduit bodies come in different shapes or styles, such as LB (ell), LR (elbow), C (pull), T (tee), LL (ell), or LR (elbow). The shape or style of the conduit body must be indicated. 5. Conduit compatibility: The conduit body type must specify the type of conduit it is intended to accommodate. conductor in a conduit body increases the amount of heat generated in the confined space, while also decreasing the ability to dissipate that heat. The National Electrical Code (NEC) limits the fill ratio of conductors in conduit and fittings to keep heat levels within safe limits, without the need for derating. The PVC conduit fill table helps calculate the safe number of THWN or THHN wires that can fit in PVC conduit tubing. It lists conduit sizes (Schedule 40 or 80) horizontally and wire gauges (AWG or MCM) vertically to display the maximum number of wires allowed for each combination according to the 2020 NEC code. Trade Size.Two sections refer to box fill calculations: 314.16 (A) Box Volume Calculations, and 314.16 (B) Box Fill Calculations. In no case shall the volume of the box, as calculated in 314.16 (A), be less than the fill calculation as determined in 314.16 (B). Requirements for calculating the minimum volume for conduit bodies are located in 314.16 (C). Raceway Fill Calculator. The purpose of this calculator is to determine one of two values: the maximum number of conductors (wires) that can fit into a given type and size of raceway, or the minimum trade size of a raceway that is required for a given combination of conductors (wires). All calculations are based on the National Electrical Code®.
