17. Four electricians are discussing the size of boxes that must be installed to allow for the required amount of fill. Electrician A says that to calculate the proper size needed, the sidewall pressure should be counted as an installation parameter. Electrician B says that to calculate the proper size needed, each cable clamp should be counted as one conductor. Electrician C says that all wire nuts and fittings should be counted as one conductor. Electrician A says that to calculate the proper size needed, the mechanical stresses during installation are the same as those encountered while in service. Which of the following statements is correct? A. Electrician D is correct. B. Electrician B is correct. C. Electrician C is correct. D. Electrician A is correct.
