It'd help if you used a 300A ampacity wire or higher. The 350 KCMIL wire is ideal for 100 feet distance, 200-amp service, as seen from the KCMIL list.For 200 amp panel that's 300 ft from the main service, you'll need to adjust the wire size for 266 amps (with the 83% standard considered). We got it with the following equation: 200 x 160% = 320A. 320A x 83% = 266A. Checking Table 310.16 again, that means you need at least to use 300 MCM copper or 400 MCM aluminum.The ground wire, often referred to as the grounding electrode conductor, is the link between the ground rod and the service ground connection. Ground wires for residences typically are made of copper and are #6 (6 AWG) or larger. For 200 Amp services, a #4 grounding electrode conductor (ground wire) is required.Above the 800 amp breaker, the ratings hold at the 380 rating.
