What should be verified before starting a DC motor to ensure safety?

• A. It is properly oiled
• B. It securely connects to a substantial load
• C. It is the correct size for the application
• D. It is operating at the right voltage

Answer: (B)

Before starting a DC motor, it is crucial to verify that it securely connects to a substantial load. This step is essential for safety and operational efficiency. A motor designed to operate with a specific load is optimized for its intended application. If the motor is started without a proper load, it may run at high speeds, leading to excessive wear, overheating, or even mechanical failure. Additionally, connecting the motor to a substantial load prevents the possibility of it running unloaded, which can create hazardous conditions, including potential damage to the motor or surrounding equipment. Ensuring that the motor is securely connected to the load allows for safe operation while minimizing the risk of accidents or component failure, making it a critical step before initiating operation.
