PVC conduit, fittings, and connectors are manufactured in sizes up to what maximum size?

• A. 1/2 inch
• B. 3 inches
• C. 4 inches
• D. 6 inches

Answer: (D)

Conduit sizing for PVC electrical systems is standardized in catalog sizes, and the largest standard nonmetallic conduit size you’ll commonly find in fittings and connectors is six inches. This means PVC conduit, along with its fittings and connectors, is manufactured up to a 6-inch diameter, covering everything from the smaller half-inch sizes up to the 6-inch size. For projects needing larger conduits, a different material or system is typically used, since 6 inches is the practical maximum for standard PVC conduit.
