Aluminum 4/0 wire car carry 180 amps at at 75 degrees Fahrenheit or 205 amps at 90 degrees. .
3/0 gauge
At the service entrance you will need AWG 1/0 gauge.
As a service entrance wire you need AWG # 3/0 gauge copper.
There are two distinct questions here. To determine the wire size to carry 15000 volts the circuits load amperage must be stated. The wire size for a 550 amp service is, an 800 MCM copper conductor with an insulation factor of 90 degrees C. This conductor is rated at 555 amps. Parallel 250 MCM will give you a total capacity of 580 amps. A triple run of 2/0 will give you a total capacity of 585 amps.

3/0 gauge
Each hot leg to the neutral wire of the service has the ampacity of 200 amps, that is why 3/0 wire is required. A 3/0 copper wire with an insulation factor of 90 degrees C is rated at 210 amps.
To carry 300 amps of current, you would need a very large wire size, likely in the range of 3/0 or 4/0 gauge wire. It's important to consult with an electrician to ensure the wire size meets building codes and safety standards for such high amperage.

A zero gauge wire can typically handle up to 300 amps of current. However, the exact capacity may vary depending on the specific wire material and insulation used in the wire. It is important to consult the manufacturer's specifications for the wire you are using to determine the exact ampacity.
Service wire required is AWG # 3/0 copper.
A 4/0 copper wire can typically carry about 230-260 amps of current. The actual ampacity can vary depending on factors such as installation method, temperature, and insulation type. It is important to consult the National Electrical Code (NEC) or a licensed electrician for specific ampacity ratings.
The maximum amperage of a 0 gauge wire typically ranges from 150 to 200 amps for automotive applications. However, it is important to consult the specific manufacturer's guidelines and consider factors such as temperature and installation conditions to ensure the safe use of the wire.

No, you cannot run two 60 amp sources in parallel to get 100 amps out because each source will still provide a maximum of 60 amps. When you connect them in parallel, the total current output will remain the same as the output of a single source, which is 60 amps in this case.
