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 250 amp 3-phase breaker, the appropriate wire size typically depends on the application, installation conditions, and the type of wire used. Generally, for copper conductors, you would use at least 250 kcmil (thousand circular mils) wire, while for aluminum conductors, 350 kcmil is commonly recommended. Always consult local electrical codes and regulations, as they may have specific requirements or adjustments based on installation specifics. Additionally, consider factors like ambient temperature and conduit fill when selecting the wire size.
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.
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.

For new 200 amp services the conduit size should be 3 inch PVC.
For three 500 kcmil (MCM) cables, you would typically use a conduit size of at least 4 inches in diameter. This is based on the National Electrical Code (NEC) guidelines, which take into account fill capacity and the need for proper heat dissipation. However, it’s essential to verify with local codes and regulations, as well as consider factors like additional conductors or bends, which may require a larger conduit. Always consult with an electrical engineer or professional for precise calculations and requirements.
For accommodating 8/3 wire, a 1-inch conduit should be used.
For accommodating 6/3 wire, a 1-inch conduit should be used.
For 10/2 wire, a 3/4 inch conduit should be used.
