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.
250 MCM aluminum minimum
50 mm or 2 inch will handle the 3/0 wires for a 200 amp service.
For Service Entrance Cable 600 kcmill (Thousands of circular mils).
For new 200 amp services the conduit size should be 3 inch PVC.
The recommended conduit size for a 200 amp service is typically 2 inches in diameter.
4 inch rigid conduit
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.
The wire to conduit chart provides information on the maximum number and size of wires that can safely fit inside a conduit based on the conduit size.

A conduit size chart for wire provides information on the recommended conduit size based on the wire gauge and the number of wires being used. It helps in determining the appropriate conduit size for safe and efficient wire installation.
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.
The conduit size chart in the National Electrical Code (NEC) provides information on the maximum number and size of conductors that can be safely installed in a specific conduit size. This helps determine the appropriate conduit size for electrical installations to ensure compliance with safety standards and prevent overheating or other hazards.
The NEC PVC conduit fill table provides information on the maximum number of conductors that can be safely installed in a PVC conduit based on the size of the conduit and the size of the conductors.
According to the NEC, a minimum of 1.5-inch conduit is required for a 100 amp service. It is important to follow local codes and regulations which may vary. Consulting with a licensed electrician is recommended for proper installation.
For a 400 amp service, you would typically use a minimum of 3-inch rigid metal conduit (RMC) to accommodate the large conductors required for that amperage. It's essential to consult local electrical codes and regulations to ensure compliance with sizing requirements for your specific installation.
50 mm or 2 inch will handle the 3/0 wires for a 200 amp service.
