The primary function of an electrical panel is to distribute electricity to multiple circuits. This central hub manages the distribution of electrical power received from the utility service or from a generator, directing it to various circuits throughout a building or facility. Along with distributing power, the panel serves an important role in ensuring safety by providing circuit breakers or fuses that protect the electrical circuits from overload and faults.

In many residential and commercial applications, the electrical panel also allows for the organization of the electrical system, making it possible for electricians to easily access and manage electrical circuits. By having this centralized point, it enables straightforward troubleshooting and maintenance.

The other options do describe various aspects of electrical systems but do not define the primary purpose of an electrical panel itself. For instance, increasing voltage is typically accomplished through a transformer rather than a panel. Converting AC to DC is achieved through rectification processes, not through an electrical panel. Reducing power loss can be a concern in designed electrical systems, but the direct function of an electrical panel focuses on distribution rather than loss minimization.
