Rigid PVC Conduit - Electrical Engineering

Rigid PVC Conduit Schedule 80 (PVC SCH 80) provides a balance physical protection for cables and conductors and helps cable inside safely from mechanical damage. It can be bent after being heated in a portable heater box. The below table of Rigid PVC Conduit is in line with NEC.
