For more advanced considerations, use the Wire Size Calculator or the Advanced Wire Size Calculator. Whether copper (no, just no) or aluminum, larger wire costs more. 200A requires either 4/0 aluminum (if the entire service feed to the main panel is 200A) or 250 kcmil. But you could power, typically, EV charging, a decent size heat pump, lighting and a whole bunch of power tools with a lot less.When looking for a 200 amp service entrance wire size, you should consider the 3% allowable voltage drop by NEC standards. As a result, you need to use a much bigger wire size than the one for short-distance setups. In this case, instead of using a 2/0 copper wire, you should use 300 kcmil copper with only a 2.78% voltage drop.The Wire Size Calculator below will calculate the proper wire size for a circuit based on circuit amps, preferred (or available) wire insulation, conductor type and installation specifications. For more advanced considerations, use the Wire Size Calculator or the Advanced Wire Size Calculator.The National Electrical Code requires a minimum of 2/0 AWG for copper wire and 4/0 aluminum wire or copper-clad wire when installing a 200-amp panel. However, …As we will see in the NEC ampacity chart, copper wires can handle more amps than same-size aluminum wires. That’s because copper has a lower resistivity (1.72 × 10 -8 Ohm×m at 68°F) than aluminum (2.65 × 10 -8 Ohm×m at 68°F). That means that the conductivity of copper is higher than the conductivity of aluminum. Temperature.Apr 10, 2021 · An often-used rule-of-thumb is to jump up one wire size for each 100 feet of a long run. SERVICE SIZE WIRE SIZE. 100 amp #4 and #3. 125 amp #2 or #1. 150 amp #1/0. 200 amp #2/0. 225 amp #3/0 or #4/0. The neutral wire is often one or two sizes smaller than the two hots. The correct sizing of the neutral depends on doing a calculation of the ... .
