The key parameter in sizing wire is the current requirement. Once you know that you can look up value in a wire gauge table. The length of the run is important for longer runs because of the resistance of the wire itself. Aluminum wire requires a larger diameter than copper for the same current. Once you calculate the wire size you can then size the conduit.
250 MCM aluminum minimum
depends on size....
No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the 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.

ma - male adapter, fa - female adapter, coup - coupling, conn - connector, cap - end cap, reducer - bushings that reduce the size of a conduit to allow connection to a smaller size conduit, expansion joints - to allow the expansion and contraction in the conduit system.
For a 200 amp service over a 400 foot run, you would need to use at least a 2-inch conduit to accommodate the size of the aluminum wire required. You would typically use 3/0 aluminum wire for this setup to ensure efficient power transmission and meet code requirements for voltage drop. It's recommended to consult with a licensed electrician to determine the exact specifications for your specific setup.
4 inch rigid conduit
For a 100A subpanel, a minimum of 1.5-inch Schedule 80 PVC conduit or 1.25-inch rigid metal conduit is recommended. As for the aluminum wire, for a 100A feeder, you would typically use 1/0 AWG aluminum wire for a 3-wire setup or 2/0 AWG aluminum wire for a 4-wire setup. Always consult local electrical codes and a licensed electrician for precise specifications for your installation.
Actual hole size for 1 inch conduit is 1.362"
The size of conduit is based on the size of the wires in it. The size of the wires depends on the load connected in the house. Without these other two values an answer can not be given.

For new 200 amp services the conduit size should be 3 inch PVC.
