An electrical sub panel, also known as a sub distribution board or sub circuit breaker panel, is a smaller secondary panel connected to the main electrical panel in a building. It serves as an extension of the main electrical panel to distribute power to different areas or circuits. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. A feeder usually begins with a feeder breaker at the distribution substation. Many feeders leave substation in a concrete ducts and are routed to a nearby pole. It helps organize, protect, and control electrical connections in residential, commercial, and industrial electrical systems. You lower the chance of circuits getting too hot or overloaded when you pick the right box for your needs.

Rural distribution is mostly above ground with utility poles, and suburban distribution is a mix. Closer to the customer, a distribution transformer steps the primary distribution power down to a low-voltage secondary circuit, usually 120/240 V in the US. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. A feeder usually begins with a feeder breaker at the distribution substation. Many feeders leave substation in a concrete ducts and are routed to a nearby pole. These systems differ in voltage levels, power capacity, and infrastructure requirements, making. Understanding the fundamental distinction between Primary and Secondary distribution in electrical systems is pivotal for designing efficient and reliable electrical distribution systems tailored to specific needs across various domains.

Regulations differ widely from country to country. A single RCD installed for an entire electrical installation provides protection against shock hazards to all circuits, however, any fault may cut all power to the premises. A solution is to create groups of circuits, each with an RCD, or to use an RCBO for each individual circuit. In Australia, residual current devices have been mandatory on power circuits since 1.
