What is number 2 Thhn wire rated for?
Type THHN-THWN-2 is permitted for new construction or rewiring for 600-volt applications. Applications requiring Type THHN or THWN-2, the conductor is appropriate for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C in oil or coolants.
How many amps can #2 copper wire carry?

What size wire do you need for a 100 amp service?
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)
What is the difference between Thhn and THWN 2?
The main difference between these two standards is their maximum temperature in wet locations. THWN has a maximum temperature of 90°C in dry and wet locations, whereas THHN wire can only be used in temperatures as high as 75°C in wet locations. However, most of these wires, so you can use THHN and THWN interchangeably.
