This PVC conduit fill table is used to determine how many THWN or THHN wires can be safely put into PVC conduit tubing. Each row going across is a different size of PVC conduit (Schedule 40 or 80). Each column (going up and down) is a different gauge of wire.
Use the below charts to determine the number of wires that can be put into conduit tubing, while maintaining NEC standards. ENT (Electrical Non-Metallic Tubing) Conduit Fill Tables. Maximum Number of Concentric Stranded Conductors in Electrical Nonmetallic Tubing (ENT)
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.
