If flexible cords with attachment plugs are used, is a receptacle required?

The use of flexible cords with attachment plugs typically necessitates the presence of a receptacle to ensure safe and proper electrical connections. Flexible cords are designed for temporary wiring and often connect appliances and devices to power sources. The requirement for a receptacle ensures that there is a safe point for these cords to plug into, allowing for proper grounding and preventing direct connections to circuits that could lead to hazards.

Having a receptacle provides a designated interface that adheres to the National Electrical Code (NEC) standards, promoting safe practices in electrical installations. It helps prevent the risk of electrical shock or fire that could arise from improper connections or using flexible cords that are not intended for permanent wiring solutions.

In this context, the other options do not align with standard safety practices outlined by electrical codes and do not address the essential nature of maintaining a safe installation when utilizing flexible cords with attachment plugs. The clear guidelines indicate the importance of receptacles in such a setup, reinforcing safety and functionality in electrical work.
