How many watts can run through 10-2 wire?

The 10-2 wire is typically rated for a maximum of 30 amps. To calculate the wattage that can run through this wire, you can use the formula: Watts = Volts × Amps. For a standard 120-volt circuit, this equates to 3,600 watts (120V × 30A). In a 240-volt circuit, it would be 7,200 watts (240V × 30A).
