Branch Breaker

Definition

A switch that stops the flow of current by opening the circuit automatically when more electricity flows through the circuit than the circuit is capable of carrying. Resetting may be either automatic or manual.

Purpose

Branch breakers protect electrical circuits from overloads and short circuits by automatically shutting off the flow of electricity when a fault is detected. This prevents potential damage to electrical systems and reduces the risk of fire.

Examples of Use

• Installing branch breakers in residential electrical panels to protect wiring and appliances from overcurrent.
• Using branch breakers in commercial buildings to ensure the safety of electrical systems and prevent equipment damage.
• Applying branch breakers in industrial settings to protect machinery and prevent electrical fires.

Related Terms

• Circuit Breaker: A device designed to interrupt the flow of electricity in a circuit when a fault is detected.
• Overcurrent: A condition where more current flows through a circuit than it is designed to handle, potentially causing damage or fire.
• Short Circuit: An electrical fault where a low-resistance connection forms between two conductors, causing excessive current flow.

Notes

Branch breakers should be selected based on the specific requirements of the electrical system they are protecting. Regular testing and maintenance are important to ensure their proper function.
