Question

1. One
2. Three
3. Four
4. Six

Answer 1

The number of disconnects that can be utilized before a main disconnect switch is required depends on the electrical code regulations.

Step-by-step explanation:

In electrical systems, a main disconnect switch is typically required to safely shut off power to a building or facility. The number of disconnects that can be utilized before the main disconnect switch is required depends on the specific electrical code regulations in the jurisdiction where the system is being installed.

For example, in the United States, the National Electrical Code (NEC) requires a main disconnect switch for any building or facility that has more than six service disconnects or six sets of service entrance conductors. Therefore, the correct answer to your question would be 4, as four disconnects can be utilized before a main disconnect switch is required according to NEC.
