Quizplus · Accepted Answer

The overcurrent protection at the beginning of the tap is greater than the ampacity of the smaller conductor. This is because the overcurrent protection device is sized based on the larger conductor to which the smaller one is tapped, allowing for the protection of the system while accommodating the larger conductor's capacity.
