A 50-ampere, 120/240-volt branch circuit is supplying a vending machine. What is the minimum size of the overcurrent protection required for this circuit?
- A25-ampere
- 50-ampere
- C75-ampere
- D100-ampere
Exam tip
Ensure you understand the requirements for overcurrent protection based on the type of load.
Why B is correct
According to 210.11(B), the overcurrent protection for a vending machine must be not less than the rating of the branch circuit. Therefore, the minimum size of the overcurrent protection required is 50 amperes.
