With a 250 MCM copper conductor delivering 200 amps on a 240 volt system, a maximum distance of 278 feet will be allowed. This distance will hold the voltage drop to less than 3 percent.
For a 200 amp service with a 60 foot run, it is recommended to use 3/0 AWG copper wire or 250 kcmil aluminum wire to ensure proper voltage drop and capacity for the load. Be sure to consult with local codes and a licensed electrician for specific requirements and installation guidance.
Hire an electrician. Do not install your main service yourself. It must meet code, it must follow many regulations to the letter, it must be inspected, and it must be done my a licenced professional. You will not save money by trying to do it yourself, and it is illegal. Chances are your power company will not connect service if it is not installed by a licenced professional.
A 350 MCM copper wire with an insulation factor of 90 degrees C is rated at 325 amps. If the question is referring to maintaining a load of 300 amps then you have to up size the wire size because the conductor is only allowed to be loaded to 80%. A 500MCM copper wire with an insulation factor of 90 degrees C is rated at 395 amps x 80% = 316 amps.
At least 000 AWG copper or better yet, 0000 AWG copper. Another consideration is how far the 200 Amps are to be carried. Wire has resistance and 0000 copper has a resistance of .04901 Ohms per thousand feet. At 200 Amps, this means that over one thousand feet the voltage will be 9.8 Volts lower than at the starting point.
A 750 MCM wire with an insulation factor of 90 degrees C is rated at 500 amps. De rated to 80% will allow 400 amps on the wire. A 900 MCM wire with an insulation factor of 75 degrees C is rated at 520 amps. A 1500 MCM wire with an insulation factor of 60 degrees C is rated at 520 amps. Parallel 250 MCM will give you the same usage. A 250 MCM wire with an insulation factor of 75 or 90 degrees C are rated at 255 and 265 respectively. 255 x 2 = 510 x 80% = 408 amps. 265 x 2 = 530 x 80% = 424 amps.
A 200 amp service panel with a 60 amp sub-panel.
Minimum size grounding conductor for a 200 amp service entrance is #6 bare copper. The conductor connected to a metal water pipe, or whatever your primary grounding electrode is, is required to be #4 copper. This size requirement is often missed. The conductor connected to a ground rod is only required to be #6 regardless of the size of service. Typical installation is #6 bare solid copper.
For a 200 amp service with a 60 foot run, it is recommended to use 3/0 AWG copper wire or 250 kcmil aluminum wire to ensure proper voltage drop and capacity for the load. Be sure to consult with local codes and a licensed electrician for specific requirements and installation guidance.

A wire size of 250 MCM will limit the voltage drop to 3% over a distance of 200 feet.
A 750 MCM wire with an insulation factor of 90 degrees C is rated at 500 amps. De rated to 80% will allow 400 amps on the wire. A 900 MCM wire with an insulation factor of 75 degrees C is rated at 520 amps. A 1500 MCM wire with an insulation factor of 60 degrees C is rated at 520 amps. Parallel 250 MCM will give you the same usage. A 250 MCM wire with an insulation factor of 75 or 90 degrees C are rated at 255 and 265 respectively. 255 x 2 = 510 x 80% = 408 amps. 265 x 2 = 530 x 80% = 424 amps.
You'll need to use # 3/0 THHN or THHW. At 145-150 ft., you shouldn't experience any substantial voltage drop but you will have some. So, If you want to be prudent, you may want to step up to 4/0 gauge wire. 3/0 copper wire with a insulation factor of 90 degree C is rated at 210 amps. 250 MCM aluminum wire with an insulation factor of 90 degrees C is rated at 215 amps.
Yes. It ranges from $200 to $250 per line.
