If by "depth" you mean the working space about a 200 amp service, it would be at least 30 inches wide or the width of the equipment (whichever is greater), by 36 inches out from the front and 6 1/2 feet high or to the top of the equipment (whichever is greater).

The minimum depth requirement for a 200 amp electrical service conduit is typically 24 inches deep in non-freezing soil conditions. However, local building codes may vary, so it's important to consult with your local building department for specific requirements in your area.
No, it is not safe or recommended to connect a 200 amp service to a 125 amp panel. The panel must be rated to match the amperage of the service to avoid overloading the panel and potential fire hazards. It is important to upgrade the panel to match the service amperage.
No, each size service needs its own meter base.
Currently, there is no manufacturer that makes a main breaker 200 amp service with built-in 200 amp ground fault circuit interrupter (GFCI) protection. GFCI protection is typically provided through individual GFCI outlets or circuit breakers installed within the electrical system.
For a 200 amp service, it is recommended to use 3/0 copper or 4/0 aluminum wire. These wire sizes are suitable for handling the electrical load of a 200 amp service with the appropriate safety margin. It is important to consult with a qualified electrician and adhere to local electrical codes when determining the wire size for a 200 amp service.
Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor. From the 200 amp feeder panel you will require a 100 amp two pole breaker for each of the two 100 amp services. Keep in mind that if you run the 100 amp services close to maximum this will take away the capacity of the 200 amp service for other branch circuits coming off of it. Also keep in mind that if the panels are located, not in the same building as the 200 amp service that the 100 amp panels will be treated as separate services and will have to be constructed like a 100 amp service. This includes ground rods. Also the bonding screw will have to be removed that connects the neutral buss to the panel enclosure.
