Question

In a typical home electrical panel installation the main ground wire is connected directly from ground rod driven into the ground to the _? a) case of distribution panel b) main breaker switch c) live bars d) electric meters

Answer 1

a) case of distribution panel

Step-by-step explanation:

It is connected to the case of the distribution panel. This is because, the distribution panel case serves as a neutral for the circuits in the electrical wiring. This neutral is also the ground since the ground wire is connected to it. It is connected thus incase there is an excess current in the circuit, it will thus flow to the ground through the distribution board case, thereby preventing electric shock. The ground or earth serves as a reservoir of charge so, all excess charge flows into it.

Answer 2

The correct answer is A) case of the distribution panel

Step-by-step explanation:

In compliance with the provisions of Article 250 of the National Electric Code of the United States, the ground wires of the distribution panel must be connected back to the neutral electric wires.

This helps to minimize electrical shock risks.

If there is a malfunction with respect to connections from the line to the case, the resulting current from the flaw will be transmitted through the ground wire of the appliances to the distribution panel where it connects to the neutral line, running straight back to the mid-tap of the service transformer from through the main neutral.
