Firstly, lets get the terminology straight because it is confusing. A 200 amp service has a 200 amp meter base that is rated 160 amps for continuous load but rated 200 amps for non-continuous loads. A 400 amp meter base is rated 400 amps non- continuous loads and 320 amps (80%) for continuous loads.

200 amp x 100% / 80% = 250 amps (to account for the 80% rule) Next, determine how long your wire run is. Add 20% for 100 feet and 10% for 50 feet. So, if your run is 150 feet, you’ll need to increase the amperage of the wire by 30%. Hence: 250 amps x 1.3 = 325 amps. The conduit size should be able to carry 325 amps.
