When installing a 200 amp service, you will need at least 3/0 AWG copper wire or 4/0 AWG aluminum or aluminum copper-clad wire. The National Electrical Code (NEC) requires a minimum of 2/0 AWG for copper wire or 4/0 AWG for aluminum or copper-clad wire. The correct wire size for a 200-amp service according to the NEC is 2/0 AWG for copper wire or 4/0 AWG for aluminum or copper-clad wire. The 250 KCMIL wire is the perfect size wire for 200 amp service because it has 255A ampacity (a minimum of 250A ampacity requirement is satisfied) . At 400 feet, the gauge wire for 200 amp service should either be 350 MCM copper or 500 MCM aluminum. To summarize, the wire size for a 200 amp service should be at least 2/0 AWG for copper wire or 4/0 AWG for aluminum or copper-clad wire, but the size may need to be adjusted based on the distance from the main service and other factors. It is recommended to consult with a licensed electrician to determine the appropriate wire size for your specific situation.
