The spelling of the word "service panel" is straightforward, with each word being spelled phonetically. "Service" is pronounced /ˈsɜːrvɪs/, with the stress on the first syllable and the "e" in the second syllable pronounced like "u" in "hurt." "Panel" is pronounced /ˈpænəl/, with the stress on the first syllable and the "a" pronounced like "ae" in "cat." Together, the phrase refers to a component in an electrical system that controls the flow of power between the main power source and individual circuits.
A service panel, also known as an electrical panel or breaker box, is an essential component of the electrical system found in residential, commercial, and industrial buildings. It serves as the primary control center for distributing electricity throughout the structure.
The service panel acts as a junction point where the incoming electrical supply from the utility company is received and then distributed to various circuits throughout the building. It typically consists of a metal enclosure or cabinet that houses multiple circuit breakers or fuses. These breakers or fuses act as protection devices, preventing excessive current flow and potential electrical hazards such as short circuits or overloads.
The service panel is usually located in a readily accessible area, such as a utility room, basement, or garage. It connects to the main electrical service entrance, typically through a meter, where the utility company measures the consumed electricity.
Within the service panel, the branch circuits are divided and individually protected by circuit breakers or fuses. These circuits supply power to various areas and devices within the building, such as lighting, outlets, appliances, and heating/cooling systems.
Proper maintenance and regular inspection of the service panel are crucial to ensure safety and efficient operation of the electrical system. Upgrading or replacing a service panel may be necessary when additional circuits are required or to meet the electrical demand of modern appliances and technologies.
The word "service panel" originates from the combination of two words: "service" and "panel".
1. Service: The word "service" comes from the Old English word "sērfe" which means "act of serving" or "duty". It can be traced back further to the Latin word "servitium" meaning "slavery" or "servitude". Over time, "service" developed various meanings related to performing a task, helping others, or providing assistance.
2. Panel: The word "panel" has its roots in Old French, derived from the Latin word "pannellus" meaning "small cloth" or "piece of material". It referred to a piece of wood or other material used in constructing something, such as a door or a cabinet. Later, "panel" evolved to mean a flat and usually rectangular surface within a larger structure, often used for displaying information or controlling systems.
