Final answer:
The conductor from the meter base is connected to individual circuit breakers in a junction box, which is connected to separate circuits for distribution in a structure.
Step-by-step explanation:
The appropriate answer to the given question is b) Junction box.
The junction box is where the conductor from the meter base is connected to individual circuit breakers, which are then connected to separate circuits for distribution to various locations throughout the structure. It helps organize and protect the electrical wiring connections.
For example, in Figure 20.25 (a), a fuse is shown to have a metal strip with a low melting point that breaks the connection of a circuit to a voltage source when overheated by excessive current. On the other hand, (b) shows a circuit breaker with a bimetallic strip that bends if overheated, breaking the electrical connection.
