2.1.1.5
Plastic Conduit for Direct Burial
**************************************************************************
NOTE: Close coordination with drawings is
important. Make sure drawing terminology is correct
("conduit" where direct buried, and "duct" where
concrete encased). If drawings require plastic
conduit, refer to NEMA TC 2 for EPC-40-PVC for
general underground direct burial use, and for
EPC-80-PVC where additional crushing or impact
strength would be appropriate. For plastic duct
refer to NEMA TC 6 for type EB.
