Description / Abstract:
NEMA TC 2-2013 covers the following types of Electrical
Polyvinyl Chloride (PVC) Conduit (EPC), which may be constructed of
single, solid layer of PVC, or may be constructed of multiple
layers of PVC, one of which may be cellular (foamed) PVC. The
designations "40" and "80" refer to Schedules 40 and 80 (EPC- 40
and EPC-80), respectively, of Iron Pipe Size (IPS) dimensions.
Common uses for these designations are:
a) EPC-40—Electrical conduit designed for normal-duty
applications aboveground; concrete-encased applications or direct
burial. May be referred to as "heavy wall."
b) EPC-80—Electrical conduit designed for heavy-duty (areas of
physical damage) applications aboveground; concrete-encased
applications or direct burial. May be referred to as "extra heavy
wall."
Note: The values stated in U.S. customary units are to
be regarded as the standard.
