To determine the power consumed in watts when a load of 20 amps is connected to a 120-volt circuit, you can use the formula for electrical power:

[ \text{Power (P)} = \text{Voltage (V)} \times \text{Current (I)} ]

In this case, the voltage is 120 volts and the current is 20 amps. Plugging those values into the formula gives:

[ P = 120 , \text{volts} \times 20 , \text{amps} ]

[ P = 2400 , \text{watts} ]

This calculation shows that the power consumed when a 20 amp load is connected to a 120 volt circuit is indeed 2400 watts. This answer highlights the direct relationship between voltage, current, and power, which is a fundamental concept in electrical theory relevant to a Limited Licensed Electrician's understanding of circuits and load calculations.

Other answer choices represent different calculations or misunderstandings of the formula but do not align with the correct application of the power calculation in this scenario.
