Question

A 240 volt transformer with a primary current of 13 amperes will have a primary overcurrent protections only of a largest of?

a) 13 amperes
b) 15 amperes
c) 20 amperes
d) 30 amperes

Answer 1

The primary overcurrent protection for a transformer should be at least the maximum primary current. In this case, the correct answer is option a) 13 amperes.

Step-by-step explanation:

The primary overcurrent protection for a transformer is determined by the maximum current the transformer can handle without damaging itself. In this case, the primary current of the transformer is given as 13 amperes. Therefore, the primary overcurrent protection should be at least 13 amperes, as the transformer will not exceed its primary current rating of 13 amperes. So the correct answer is option a) 13 amperes.
