Gas Heat ESCO Practice Exam

The correct answer is 12-14 AWG. This size of conductor would typically be used for an electrical circuit connected to an 80,000 BTU gas furnace with a 3-ton cooling system and a fan motor rated at 1/3 HP @ 120 VAC. The size of the conductor is determined by the electrical load of the equipment being connected, as well as factors such as the voltage and allowable voltage drop. In this case, the 12-14 AWG conductor is appropriate for the given equipment specifications and electrical requirements. Option A (14-16 AWG), Option B (16-18 AWG), and Option D (10-12 AWG) are not the correct choices for this scenario as they do not align with the electrical needs of the gas furnace and cooling system described in the question.
