The PVC conduit fill chart is a table used to determine the maximum number of wires that can be safely installed in PVC conduit tubing based on the size of the conduit and the gauge of the wire. The chart provides information on the allowable number of wires for each combination, taking into account the requirements set forth by the National Electrical Code (NEC) or other applicable standards. It is an essential tool for electricians and engineers working on wiring projects that involve PVC conduits.

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.
