What is the primary purpose of a panelboard?

• A. To protect against cyber threats
• B. To distribute electrical power to various branch circuits
• C. To serve as a backup power source
• D. To monitor energy usage

Answer: (B)

The primary purpose of a panelboard is to distribute electrical power to various branch circuits. A panelboard serves as a central point where the electrical supply enters and is then distributed to different circuits throughout a building. This is essential for the effective management of electrical energy, ensuring that power is safely and efficiently routed to different areas that require it, such as lighting, outlets, and machinery. By providing this distribution, the panelboard allows for the regulation of circuit capacity and aids in the protection of electrical equipment and appliances by using circuit breakers or fuses. It is fundamental in residential, commercial, and industrial electrical systems, making it a critical component for maintaining orderly and effective power distribution.
