50 mm or 2 inch will handle the 3/0 wires for a 200 amp service.
30 amps will require the use of AWG #10 wire. You can easily run one #10 wire in a 3/4" conduit.
120mm
For new 200 amp services the conduit size should be 3 inch PVC.
2 inch Rigid or IMC conduit if it's on a structure. 2 inch schedule 80 PVC conduit if it's on a wood pole.
Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
A 200 amp service panel with a 60 amp sub-panel.
Depends on the size of the service. 100 amp service will require 3 gauge, 150 amp service will require 1/0 gauge, and 200 amp service will require 3/0 gauge.
4 inch rigid conduit
4 inch rigid conduit
For new 200 amp services the conduit size should be 3 inch PVC.
Three number three wires can be installed in an inch and one quarter conduit.
A #6 copper conductor is used to bond a 200 amp distribution.
You do not use a ground wire in the connection from the meter base to the distribution panel. A bonding wire may be required if the service is using PVC conduit.
No, each size service needs its own meter base.
2 inch Rigid or IMC conduit if it's on a structure. 2 inch schedule 80 PVC conduit if it's on a wood pole.

Your service provider will give you that information The size will depend on: A) how close to the transformer are you. B) copper or aluminum C) Yes, you have a 400amp service but what will your actual peak amp usage be. D) Underground or overhead.
