What standard breaker is designed to protect a single branch circuit?

A. Single-pole, 40 amp

B. Single-pole, 30 amp

C. Double-pole, 15 amp

D. Single-pole, 15 or 20 amp

Answer:

A single-pole breaker is designed to protect a single branch circuit.

Explanation:

A standard breaker is an electrical device used to protect electrical circuits from damage caused by excessive current. It automatically interrupts the flow of electricity when the current exceeds a certain level, preventing overheating and potential fire hazards.

In the case of a single branch circuit, which supplies power to a specific area or appliance, a single-pole breaker is typically used. A single-pole breaker is designed to handle a maximum current of either 15 or 20 amps, depending on the specific model.

It is commonly used in residential and commercial applications to protect individual circuits. Understanding the type of breaker designed for a single branch circuit is important for ensuring the safety and proper functioning of the electrical system.
