Electrician A says that to ensure proper ventilation, the required clearances aren't found on the transformer nameplate markings. Electrician B says that exposed live parts on a transformer require the installation of a sign that indicates the operating voltage. Electrician C says that exposed live parts on a transformer don't require the installation of a sign that indicates the operating voltage. Electrician D says that to ensure proper ventilation, the required clearance must be checked on the transformer nameplate and in the manual. Which of the following statements is correct? A.
