Final answer:
The correct term for the first point of disconnect for conductors from the utility company is the service panel or the main panel. The closest option provided in the question is the distribution panel. Grounding is a safety measure where a conductor is connected to the earth to establish a zero volt reference point.
Step-by-step explanation:
The first point of disconnect for the conductors from the utility company is called the service panel or main panel. The correct answer is not explicitly listed in the provided options, but the concept closest to the service panel mentioned in the question's choices would be the distribution panel (B). It's important to clarify that a subpanel (A) is a panel subordinate to the main panel, a circuit panel (C) could refer to any panel with circuit breakers, including a main panel, and a satellite panel (D) is not a standard term in this context.
Regarding grounding, it's key to understand that grounding is the process where a conductor is connected to the earth, establishing a reference point of zero volts. This is an important safety measure in all electrical systems, including the main service panel.
As for the high-voltage wires, the statement about them being insulated is false (B). Those high-voltage wires that you see connected to tall metal-frame towers are indeed held aloft by insulating connectors, but the wires themselves are not wrapped in an insulating material. They are bare and rely on the air and distance for insulation.
