Identify one common method of disconnecting loads safely.

Using a circuit breaker is a common method of disconnecting loads safely because it is designed to interrupt the electrical circuit when an overload or short circuit situation occurs. Circuit breakers automatically cut off the power supply when they detect an anomaly, providing an essential safety measure to prevent overheating, fire hazards, or damage to electrical equipment. They are also user-friendly and can be manually operated to disconnect loads for maintenance or troubleshooting, ensuring that technicians can safely work on electrical systems without the risk of accidental energization. This combination of automatic and manual operation capabilities makes circuit breakers a reliable choice for safe disconnection of loads in electrical systems.
