8. Two electricians are discussing the requirements associated with two common household
items. Electrician A says that a 220-volt room air conditioner with a 10-foot
cord follows the NEC, as long as the load doesn't exceed 80 percent of the circuit
with which it will be used. Electrician B says that the cord for a household refrigerator
