10

Which state agency oversees the licensing board responsible for electrical contractor licensing in Ohio?

Question 11

11

16

A branch circuit supplies both a continuous load and a noncontinuous load on the same overcurrent device. How must the device rating be calculated under the NEC?

Question 17

17

Why must the equipment grounding conductor never be sized based on the ungrounded conductor's actual carried load current?
