What is the maximum length of a flexible cord connected directly to a busway plug-in device?

The correct maximum length for a flexible cord connected directly to a busway plug-in device is 6 feet. This limitation is established to ensure safety and prevent potential hazards associated with excessively long flexible cords, which could lead to damage or increased risk of tripping and electrical failures. The regulation aims to encourage proper cable management within electrical installations and maintain a safe working environment.

In practical terms, adhering to this maximum length allows for easier access and movement without compromising the integrity of the electrical connection. Longer cords could create complications, such as increased voltage drop and potential overheating due to excessive length, which is why they are restricted. This standard is part of broader electrical code requirements aimed at promoting safety in installations involving flexible cords.
