You can pull 10 #3 gauge wires in a 2 1/2" conduit.
For new 200 amp services the conduit size should be 3 inch PVC.
A trade size hole for a 2-1/2" EMT conduit connector, the hole needs to be 2-7/8" in diameter. A 3" rigid conduit can also use this size hole without the lock nuts falling into the hole.
The required size of a conduit raceway for a 3-5000 mcm wire is 300 kcmil. It maximizes the limits on the wire fill for raceways.
For a 240 volt, 50 amp circuit, you typically use a minimum of 3/4 inch conduit for copper wire and 1 inch conduit for aluminum wire, assuming you are using THHN or THWN wire. The specific size may vary based on the number of conductors and any bends in the conduit. Always consult local electrical codes and the National Electrical Code (NEC) for precise requirements and adjustments based on your specific installation conditions.
The amount of conductors per conduit size example code says 3 number 4 conductors in a 1'' conduit
The appropriate conduit size for accommodating 6/3 wire is typically 1 inch in diameter.
The recommended PVC conduit size for accommodating a 6-3 wire is 1 inch.
For accommodating 4/3 wire, a 1-inch conduit size should be used.
The recommended conduit size for accommodating 6/3 wire is typically 1 inch in diameter.
